Product Information

For the Ser IIA & III we can offer a high ratio transfer case kit.

This kit was developed as a stronger alternative to the Series "overdrive." By using the High Ratio conversion the High range is raised by 31.8% (overdrive is 27.5%) whilst leaving Low range unchanged. This suits most users who like a higher gear for on road economy, retaining the stock low range for off road use.

Other advantages of this conversion, compared with fitting 3.54 diffs, are:- the speedo drive will not need re-calibrating, there is no loss of handbrake efficiency and most importantly there is no loss of strength.

Please note this kit cannot be used as well as an Overdrive but you can still use the rear PTO.

Sorry but we are not able to offer a fitting service on this kit,

The price for the kit is £270 exchange. There will also be an additional £75 core charge. To see an explanation of the core deposit please click here

This will be refunded on receipt of your old bare casing if this is returned to us.

Please note these kits are often out of stock, this is because we are not able to source the casings to supply with the kit, as they are often sent overseas the exchange units often dont get returned, if these are showing as out of stock you can send your bare casing in to us and we can machine and return it to you with the gears for £ 270 + V, ie no core charge, please note the casing must be stripped of all studs and dowels and clean. If you have any additional servicable casings you can send these in to us in the same condition and we will purchase these for £ 50,

High ratio Transfer kit in my Swb series Landrover

I had one of these kits fitted to my Series 3 landrover which has a 2a box in it. I can honestly say it is one of the best upgrades I have done. I used to have a overdrive which gave good gear selection flexibility but it was getting very warn and a new was massively expensive to purchase. I have a good condition 2.25 litre petrol engine which pulls well originally on 7.50x16 tyres. The kit was brilliant on long runs engine noise down and a more civilised experience. Around town was fine you have to get a bit used to the different gearing but its easily adaptable. I recently changed tyres to 225/75/16 and this has helped with acceleration and starting off in 1st gear on a hill. You will have to work out your preffered set up. Iam very impressed with the product and the service from Ashcrofts. I have been running this for about 6 years.

Hi ratio transfercase

I have had an Ashcroft high ratio transfercase installed behind a fuel injected Mustang 5.0L V8 for 16 years now and it has help up without any issues. If you have a higher than stock HP engine that wants to see lower revs this is THE product to have.

High Ratio Transfer case

hi dave, just finished fitted the case. i have the two cases ready to send back and will be with you next week. i was having some trouble getting the dowels out so i left them in as you obviously have better equipment than i do. i didnt want to risk any damage by using poor removing tools. i have been out on a test run and i have to say, i am very impressed. i am yet to give it a long run but i have given it a good test and its frankly exceptional. i had been told many bad things about fitting it to a 109" due to the extra gearing of the bigger tyres. so i have a test in mind that will put it through its paces in a few different situations. a real world test, as it were. i will be writing it up for the forum i am on, simple stuff about how it works with the 109" gearing. if you would like i can send you a copy should you want it. its just something you can point people to if they ask about the gearing and if it will work, as i did. anyway, just wanted to say thanks and well done on a superb modification. cheers chris ________________________________________
