Product Information

For the Ser IIA & III we can offer a high ratio transfer case gear set. This gear set 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.

In order to fit this kit you will need to modify your existing transfer box casing in order to accept these gears. Full instructions on how to make this modification are available in the technical section.

Please note that we cannot be responsible for any noise issues that may arise caused by the incorrect machining of your casing.

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

Excellent product!

Bought the gear kit as the full kit was sold out. Ashcrofts kindly drilled my own transfer case (at cost). The modified case was excellent and the gear kit easy to assemble. A huge improvement on the Fairey overdrive, my Series 3 feels like it's been given a new lease of life, but above all the gearboxes are now so quiet as to barely be heard! Highly recommend - a modern, cost effective, high quality and robust upgrade to any Series. Makes the vehicle cope much easier with modern traffic.
