they are worth it if they are complete ie lever and drive gearfor rear of gear box and arent worn out inside teeth are usually worn and pitted making them whine

An overdrive is possiby THE best shiny bauble you will ever buy for a series vehicle (Apart from a Tdi and Lt77 obviously ;-))
Wont make it any faster on the motorway BUT will lower the revs to a slightly ear bleeding level AND improve the fuel consumption to a slightly less wallet bleeding level .
Great for occasions when 4th is too tall AND 3rd is too short especially when towing .
Make sure you buy a good un though (Ideally drive the vehicle it's coming out of ) because there are some epic mingers out there that howl like a banshee .

Before I had one my s3 was not motorway safe! Topped out at a low speed and was not pleasant even at 40mph. Overdrive made it more of a long range vehicle and more pleasant on dual carriageway or m4. Still scary mind! But much more useable with an od. I bought a whole box with an od all in perfect nick with no whines or issues for £350 so yes your od pictured is a rip off imho

£475 sounds about right for a good one, and certainly cheaper than a new "Roverdrive" at £1275..... is it worth having one???? I have one on my S3 2.25 diesel and I wouldn't be without it...makes a significant difference to comfort (Noise) and fuel economy on longer trips, plus combined with my 7.50 tyres enables me to keep up with most modern traffic.
If you only do short journeys then probably not???
Does give you an extra "gearstick" to confuse other drivers when they look in the cab, and does generally get a nod of approval when you speak to other Landy types

Looking at it, the front teeth did look in very good nick. I was tempted to offer £400, but it was still a lot to offer for somthing I have no real idea about.
This one looked to be all complete and had fitting instructions.
Apparently it came off a show vehicle that was written off.

the output teeth will look good its the inner ones onto box drive and high gears inside overdrive you need to think about

i was looking a few months ago - thinking of selling the one i got years ago and never fitted - c£500 seemed to be the going rate and as summer kicked in they seemed to drop a bit, saw one go for around £750 with all the gaskets washers etc.
guess it depends how many people are looking when you want one and whether there is a bidding war.
It also seemed that the fixed price listings for £450-£500 would stay up for a few weeks before going, yet the auction ones with the 99p start got bid up to over £500 always puzzles me why people will fight for one like that instead of just doing a bin on one that's in the right ball park
be interesting to see what the new fairey ones are priced at if they do start production later this year.
Whether having one is a good idea or not for me would depend on the payback period, i only potter about in my landy rarely get above 30 so it wouldn't be worth me getting one not for £500 anyway. If the car is ones' daily drive and dual carriageways and motorways feature a lot i would say £500 on a good one is money well spent.

If you have an engine in good nick you'll be able to get to a reasonable speed 70mph + in comfort. Cruising at 50mph is pleasant...
If you have the money a Roverdrive (now called Roamerdrive) is a much better option. It's a lot stronger so you can use it as a splitter and while towing and in low-range. All those hills where 3rd makes your ears bleed and it runs out of puff in 4th you can shove it in 3+OD for a comfortable drive. Also, if you get good at it you can get really set off by fancy footwork. I also found it useful off-road where 2nd/low was too slow and 3rd/low not quite enough to crawl up steep hills 2nd/low+OD was perfect. You don't need to **** around changing the oil either as its shared with the transfer box.

I must say, I had no idea they fetched £500 plus these days! They were £350 ish when i was looking a while back. As I said, buy one already on a box if you can and you effectively get the box for free!

Are the Ashcroft high range kits any good?
Ashcroft Transmissions
Seems to offer the benefits of an overdrive, none of the disadvantages of 3.54 diffs, and at a lower cost. Some more effort required for fitting tho... :crazy_driver:

It depends on how good your engine is, if its a weak petrol or a standard diesel you may find it lacks acceleration - same as 3.54 diffs. With Ashcroft kit the only advantage over 3.54's is you still get a really low low-range. You get the same gearing (roughly) in high as 3.54s
I've never used low range with 1st gear so can't see the point, even low 2nd+3.54's is pretty slow...maybe if you're doing a lot of careful RTV trials the super slow speed might be useful but does 0.76mph actually feel any different to 1mph?

Understood Dominic.
I would like to do some mild expeditions in mine when the time comes. At the rate that overdrive prices are going, I can't see it being a cost effective solution by the time I get round to it.
I don't think I would have a problem with 3.54 diffs as Keri low range as is isn't an issue fir me either. Is it a significant problem if you go with the diffs but don't bother with the Speedo correction?

When I fitted 3.5 diffs...I just removed the speedo...took off the glass and put a dot of white paint for every 10mph segment,
Works well for me...got the comparison speeds from a test drive with my GPS,
I had an o/d for over 35 years...never go back to one...bought it new in 75 and it was alwys noisy...they can leak a lot of oil as well so hs to be checked weekly which was a pain.

I've got used to having an uncorrected speedo - just got the main speeds remembered mine's not helped by having a 5mph offset as well as the ~33% error!
When I reckoned it up it wasn't just the saving in petrol and noise but the fact that it has made the Land Rover into something that I can use every day instead of just a noisy weekend toy, well worth the £1200 for the Roamerdrive. Certainly cheaper than buying another car. With the ACR engine stuff (2.1 head, hi-torque cams) and a new DMTL Weber carb it flies with 3.54s and is quietly rumbling along going up hills in 4th at 40-50mph more noise from the diffs and overdrive than the engine
