3MO 2WD ETV 6 speed sequential gearbox

3MO 2WD ETV 6 speed sequential gearbox with 8+8 LSD

Bestseller of 3MO 2WD range with more than 500 units all over the world, the ETV gearbox has nothing left to prove since it has won titles in every discipline : rally, rallycross, circuit, hillclimb, or in offroad. In offroad, the ETV gearbox is for example use on the Mitjet project with a rear transverse engine position. ETV gearbox is the standard private product which is based on the Citroën DS3 R3 gearbox and uses on the following one-make series : Lamera Cup, VW Polo cup India & China, GCC China, VW Ameo cup, etc.. Its high torque capacity (from 350 N.m with short final drive to 500 N.m with long final drive) makes the ETV naturally qualified for lots of applications, whereas its modularity enables to offer a specific solution for every new project.

To optimize your speedness diagram according to your application and your technical datas (engine, tyres, etc), there are dozen of ratios for each gear ratio and more than 10 different final drives are in stock.

According to the technical need of your project, the lubrication is ensured by a mechanical oil pump with internal lubrication system or with splash lubrication technology. A 4+4 discs version (16 friction faces) of the self-locking differential is available fot the most demanding projects on this matter. The 3+3 discs standard LSD (12 friction faces) with 40°/60° ramps (or 30°/60°) offers a high end differential which meets 90% of the project needs. Since 2019, our differential benefit of molybdenum friction discs. The molybdenum is a high performance friction material. It has a high level of elasticity and improves the characteristics of steel at high temperatures : smoother, higher coefficient of friction, better life-time.
