NOTE   most comments refer to the Roverdrive, which was the brand name of our overdrive unit since it was first sold in 2004.  We recently changed the name of our overdrive to the ROAMERDRIVE, and our company name to Global Roamer Corporation.

The following are comments from GLOBAL ROAMER customers.

 

“I have been running a Roamerdrive for several months now in a variety of conditions in my 1963 Series II 109 Land Rover.  The kit is very well put together and comes with excellent documentation.

Roamerdrive is quieter than the Fairey overdrive it replaced. My Land Rover was converted to a Defender 2.5 diesel. With the Roamerdrive I get 8 liters/100km. [29.4 MPG] on the highway and cruise comfortably at 100 110 km/h [60-65 mph].  This fuel consumption would make some new SUV's jealous and is almost unbelievable for a vehicle with the aerodynamics of a brick wall.  Shifting is smooth.  Roamerdrive seems to handle the diesel's beefier torque with no complaints. Noise levels at speed are within the ambiance of all the other sounds series Land Rover owners know so well.

My circumstances combine 5-6 hour highway driving with off-road work and city driving at each end of the journey.  A crucial test is climbing and descending thousands of vertical feet through the mountains of British Columbia with a full truck bed weighing several 100 lbs.  I took the trip several times this summer and Roamerdrive performed flawlessly.  The old 109 actually behaved like it enjoyed the highway along with its usual grunt work.

My full thanks to Roamerdrive for an exceptional product.”

"I just recently had a Roverdrive fitted to my S-III and like Dr. Beast have gone from 17-18 mpg to 24-25 mpg. I am probably driving it a little faster than I used to just because you can but I expect to settle down eventually. Don't know how much that will change the mileage. I am planning on keeping it forever so the investment didn't seem to hurt quite as bad. I like that it gets better mileage, is quieter, doubles the gear selection options (especially nice is splitting the 3rd to 4th gear option on hills) and reduces wear and tear on the 2 1/4. The guys at Roverdrive are great and build a top-notch product. For me it wasn't just about the mileage so it is definitely worth it."

"I now use the Roverdrive SX, having sold this Fairey unit, as the older model would not cope for long with the torque of the TDI engine in my 109. So far, I’m very pleased with it   it’s quieter, and doesn’t need weekly topping up with oil. "

"Here's my pennies worth. BUY THE ROVERDRIVE!  Ok they are expensive BUT....  They are new. They carry a warranty. They have better cooling and should be quieter than any 2nd hand OD on the market. They will hold their value and if you swap your Landy just take it with you. Think of it as an investment. The only alternative is a 2nd hand unit who's history is dubious, possibly noisy, leaky, and not as thermally efficient, and everybody wants  300 or more for them. So add the extra and get the Roverdrive."

"Why haven't I got one  I was very lucky and got a Santana OD cheaply two years ago, they are supposed to be bomb proof and have a huge oil reservoir so they keep pretty cool too. Much bigger and very different to the Toro or Fairey units. But it does leak a bit of oil and it's a bit noisy. If I hadn't got it I would be saving for a Roverdrive."

"Get a Roverdrive. Though it costs more than a Fairey, it is quieter and I'm pretty much positive that it will last longer. The input splines WILL wear out on a Fairey and it will have to be rebuilt sooner or later."

"I like the smooth, positive shifting of the Roverdrive. Well done.  And the clean well-machined castings. Very thorough and professional. The body and guts of the unit are very well put together and were a nice clean fit. It will be a few days before I have the floor and the rest of the truck assembled, but then I'll take it out on the highway and see what it can really do."

"I have been using a Roverdrive for a bit over three years, with a TDI pulling the heavy 109 on auto routes and up 1:3 ski slopes and up to 10,500' glaciers in the Alps while fully laden, and it's running beautifully. I don't think the Fairey I had before it would have survived the TDI transplant and certainly not that trip."

"I've used a Roverdrive for well over 100K miles on my 88 and it’s a good piece of kit. Comparatively quiet and adds a lot of flexibility to your gear ranges for the hills."

"Downhill, about 88 mph on the clock maximum, 205 tyres, 88" 2  liter with Turner head, Roverdrive and Santana discs to stop it! "

“Seems everybody raves about the 200tdi and 300tdi, and lots of people convert to them, but I really like the simplicity of the 2.5. It may not set the road on fire, but hey, it's not supposed to!  I imagine I might feel different if I'd ever ridden in a 300tdi, but my 2.5 in combination with the Roverdrive does just fine. Of course I don't have to deal with too many hills here in Texas either.”

"My '66 109 hardtop with Roverdrive does 15.7 mpg on LPG and 17.1 mpg on petrol."

"I would personally choose Roverdrive.  I think they've got a good reputation and I've had a Roverdrive for 4 years with no problems. Very good quality stuff."

"I would go with a really late S3 box and the Roverdrive; for those longer slogs you've got a nice strong overdrive to act as a splitter."

“I now use the Roverdrive SX, having sold the Fairey unit, as the older model would not cope for long with the torque of the TDI engine in my 109.  So far, I’m very pleased with it - it’s quieter, and doesn’t need weekly topping up with oil.”

“Although I don't have an overdrive in my vehicle I have driven a Series III shorty which had a Roverdrive installed.  Cruising at 100 km/h with little or no fuss and noise was quite easy.  The owner swore by the Roverdrive and I have heard stories about Fairey not being the best product to install.  When I have the means then I will definitely go with a Roverdrive overdrive.”

“I have had a Roverdrive installed on my truck for about 4 years and love it!  Absolutely dead quiet and very smooth shifting.  I have run it pretty hard behind a strong 3.0l turbo diesel and have had no issues.  Actually we just returned from a trip to Alaska and I couldn't begin to even dream of ever doing a trip like that without one.”

“Nick came over to install a Roverdrive with me. It took just under 2 hours to complete, and was a pretty logical process. Why a Roverdrive and not one of the other types of overdrives that are out there   Local connection to parts.  Good self oiling system. And a rather creative methodology - using a planetary gear set meshed to one end of a Series III sychro hub, from the look of it.”

"So far I'm impressed with the way it lowers the RPM, but I think, with my 33 inch tires and 2.25 petrol engine, I'll have a bit of a strain actually maintaining speed on the highway due to lack of power. I'm planning an engine replacement at some point anyway, or I'll just have to tickle some more horsepower out of this one. Ray says a bit of port and polish and shaving the head to increase compression will do the trick nicely. It may be worth the effort before going to a full engine swap, as the cost of head tweaks will only be a couple of hundred bucks, a head gasket and my time... 

 In the meanwhile, it s pretty quiet, with a slight whine, which will disappear as the new main gear wears in with the old idler. This is very minor compared to what I heard - that overdrives could be rather noisy beasts. 

“This unit literally makes it possible to run a Land Rover in the Great Race with a chance of getting good scores. With the 4.70:1 axle gears and short 6.00 x 16 tires, top cruising speed was around 55, and that's winding it pretty good. Not only does the Roverdrive provide better top end cruising, it's selectable in any ratio, so that we can sustain speeds of 35 or 40 up the steepest hills by using third/overdrive. Keeping the low overall gearing greatly improves acceleration, and at speeds up to 35 mph it's as fast as anything on the road. The unit is mounted on the back of our own rebuilt trans and t-case. We now have 16 forward speeds and 4 reverse! What we lack in power we make up for in gears.”

“I'd also like to say thanks for the Roverdrive. Trouble free for the last 5 five years I've had it.”

“Roverdrives are a great piece of kit and very reliable. For a while I was doing 1000 miles a week thundering along on the freeway. It held together very nicely, was comparatively quiet and kept the rpm down to around the 3000 to 3200 rpm for Freeway speeds. I have a lot of miles on my unit.”

“Well on my 71 IIA 88 with 30 X 9.5 rubber and a Roverdrive the speedo tells me I can push her up to 70 mph. I think that given the realms of scientific measurement error in a Rover speedo that it is more likely to be 65 mph in reality. The engine was mildly breathed on with Turner head, 2.5 cam, Rochester, K&N and electronic ignition.”

“I used to do 1K miles a week like this on the I10 between Phx and Tucson. I wouldn't say I could beat any land speed records but it was fast enough that I could happily rumble along with the big rigs in the inside lane. You still slow down on long climbs. If you stay on top of your maintenance and your revs below 4K the engine should be just fine on the freeway - if anything giving it a good blast helps blow out any carbon build up”.

“My airportable was bought almost sight unseen with a turner 2.5 (I think) and a Roverdrive that ran like a raped ape. I picked it up in Jacksonville, FL and drove straight back home to CT. On the way back I distinctly remember seeing the speedometer pass 85 mph for a short while as I was passing some big rigs and an irate Jeeper that I had just cut off.”

“Although I enjoy doing business with RDS I don't believe the Fairey OD is as good as the Roverdrive. Just one man's opinion. Not trying to start a war here.”

“After driving my rig for nearly 5 years constantly checking the transfer case fluid and cleaning (lol) my driveway, I bought an aluminum case cover from Roverdrive about 6 months ago. Holy S--T!! What a difference! No drips, no messes and the whole thing seems to be running cooler. So far it has been the best $100 I've spent. Does anyone else have any experience with this beauty ”

“I use my truck as a my daily driver, so an overdrive is a must. I've put on about 600km's this week on the Roverdrive.  It’s easy to forget its even there, which is very good thing.  The fairey was stupid loud.. earplugs were a must. It drowned out everything else completely. I’ll take a better look at it to see what’s wrong with it, but it was working perfectly then suddenly got VERY loud in a matter of seconds, so it’s not just that its worn out on areas due to use  there was a failure of some sort that caused it. I spoke to RDS and after determining that there was no way to determine what might be wrong with it, I'd have to send it down there for a hefty chunk of change then get it assessed and that could have cost as much as a new unit anyway.. even if it was deemed too worn to repair I would still be out the shipping. Just made more sense to switch to the Roverdrive and be done with it. Glad I did.  Money very well spent on this unit.  As they say, you never regret paying for quality.”

“Everything you need is included when you purchase it from Ray at Roverdrive Gear Corporation. If you have any questions give him a call, they are great to deal with and are super helpful. I love having one in my 1960 series II 109 sw... did 60 to 75 with no problem. Enjoy!”

“Man I want one of those Roverdrives!”

“I've never heard a negative word about the Roverdrive. But maybe I'm just not listening. If I was in the market today, I would probably go with the Roverdrive.”

“I also would push for the Roverdrive. I put one in last year and it has been great - quiet and reliable. Again, the highway is where you mostly use it, and splitting gears when climbing hills.”

“The Roverdrive is well worth the money. Not only do they work very well but Ray is easy to get in touch with if you do have any trouble.

I called him up a few weeks ago to help clarify something for a transmission rebuild I was doing. In the call I noted that one of the batwing washers inside my Roverdrive was getting loose and will probably need to be replaced soon. To this Ray said:   “Oh!  That sounds like a high mileage unit. If you don't mind sending it in when you get through with your travels, I'd love to show it to the boys and we can rebuild the unit for you. We don't get many units sent back to us.”  If that isn't telling about how robust they are, I don't know what is!”

“I installed a Roverdrive last fall after 6 months without any overdrive. (cringe) My Fairey disintegrated after 15+ years of use - I can't say that I didn't get some use out of it (including an Alaska-to-Argentina jaunt). But I will say that my new Roverdrive works better, is quieter and seems more robust than the Fairey. It has also actually made my transmission shift and hold gears better, maybe because the slop in my worn Fairey was facilitating it jumping out of gear. Now there's no more of that. I am aware of a slight whine while driving with it disengaged, but engaged it doesn't get any louder. Overall I'm very happy with it. It wasn't an absolutely effortless installation, but it worked OK, especially since I had already had an overdrive in there. I can recommend it highly.”

"I have/love my 110 mod 2.5 na and while I thought about a 200/300 tdi swap, I really like the simple mechanical fuel injection. My 110 came with a Roverdrive unit, similar to the old Fairy units. Seems bullet proof, really extends the top end (Got to 120 kph! and ran out of nerve). It’s another option to consider.”

“I have no personal experience with a Fairey unit, but have recent experience (last several weeks) with a new Roverdrive in my '63 SWB, 2.25 gas. I run a Rochester I recently rebuilt using a 50 main jet.  I also use the stock oil bath air filter. Before overdrive, and daily driving to/from work, etc., which here is about 19 miles each way on 2 lane roads, the Series averaged about 15 mpg without overdrive...this with fairly fresh engine (7:1). I checked fuel usage yesterday again after a couple months getting used to Roverdrive (splitting on hills, etc. as has been mentioned), and it gave just over 19 mpg. Point is not carb choice, rather the decrease in fuel usage. It is also quite smooth engaging/disengaging, and very quiet when engaged. So it is saving on fuel, wear & tear, and is far more pleasant to drive. I also drive about 55 when engaged. It will run 60-65 if called on, but not through hills. I am glad I put the Roverdrive in, it is doing what I was after.”

“I installed a new Roverdrive last year after my Fairey disintegrated. (I put over 100,000 miles on the Fairey unit, which was not new even when I got it in 1994.) I can't say enough good things about the Roverdrive unit - it's quiet, it was fairly easy to install since I had holes drilled for the Fairey anyway, it doesn't add any noise to the truck and it lowers the engine speed for highway cruising. It also offers some gear splitting capabilities and engages and disengages crisply. Their customer service is good. My Series IIA's tendency to slip out of third gear has also disappeared, making me think the old Fairey was so worn all the gears were a little sloppy. So I would recommend it.”

“I purchased my Roverdrive before I even took delivery of my series truck about a year ago...
fantastic improvement in drivability and really can’t imagine driving a series truck on the hwy without one..even around town in 40-45 mph zones the 3 1/2 gear is just perfect.”
