Ashcroft Underdrive *Porn*

20 forward gears.

It bolts to the back of your transfercase just like an overdrive does.

Bolt on Land Rover Accesories just keep getting better!!!!!

The return of the now famous UNDERDRIVE Which was originally introduced for the hardcore "rock/glacier crawlers" but has since become the favourite for the serious challenge event competitor.

For those that are not familiar with the unit, this is an additional reduction unit fitted to the LT 230, which bolts onto the Power Take Off (PTO) flange. By installing the Underdrive we have created a four range transfer case, in addition to the stock high /low we have an intermediate range and a super low range. Typically the ratios could be 1.2/1.4/1.6 high, high x 2.69 intermediate, 3.32 stock low, 8.93 (2.69 x 3.32) super low. The intermediate range is a useful gear split between stock high and stock low
High and Low ratio will remain unchanged but when selected the underdrive will give an additional 2.69 reduction, this makes a low, low ratio of 8.93 (3.321 x 2.69). This gives the best of both worlds, high stays the same for road use, you have stock low for running about between sections and you have underdrive low for crawling over obstacles or winching.
The unit will only be supplied in the 26 tooth, suffix C onwards input gear format, if you have a 28 or 38 tooth input gear fitted you will also need to change the intermediate and the high range output gear at an additional cost of £175.
Please note, although the Underdrive will fit the Disco LT230 transfer case it will foul the rear footwell so the bodywork will have to be modified to clear.



Ya can't help but feel sorry for those that have to make adapters to join two transfercases together and the modify the hell out of everything to get it to fit :mrgreen: :mrgreen:

Bad and very boring video, but you get the idea:
