Renault UN1 Gearbox Kit

These CNC machined parts are designed to allow the use of the Renault UN1 gearbox in your Volkswagen T3/T25.

The Renault UN1 gearbox in known for its strengths and has been used by builders of V8 powered kit cars for years. With some modification to your van, it is now possible to use this adaptor plate and drive flanges to mount any of the Volkswagen Transporter specific bell housings to the Renault gear box. This gives a very cost effective alternative to the use of other gear box upgrades. The UN1 transaxle has been fitted to many vehicles in the Renault range, with both front and rear engine designs. No problem if the gear box you source is from a front engine vehicle as the differential can be flipped over to the other side making it suitable for a rear engine set up

There is a good choice of bell housings available that will work with this adaptor plate:

The flat four Petrol bell housing
The four cylinder diesel bell housing (Ideal for use with a TDI conversion with the UN1 07 long ratios)
The South African bell housing (This allows for upright fitment of many of the VW Audi inline engines inc 4, 5 and 6 cylinder.
The Subaru specific bell housing. This is an option available for those wanting to use 4 and 6 cylinder Subaru boxer engines.

All of the above conversions will work with their own factory Volkswagen input shaft, making this a very easy upgrade.
