E-ROM Race/CNC71 differential with quick gear ratio change

Introducing the E-ROM/CNC71 differential with a quick-change gear ratio option.

The E-ROM/CNC71 differential assembly, featuring a quick-change gear ratio system, has been specifically designed for high-level drift competitions, which demand the utmost durability from the gearbox and rapid gear changes.

This product features a modular design with a quick-fit system, combining a robust differential housing, an integrated differential core and a set of gears with a quick-change system, which effectively eliminates the inconvenience associated with differential adjustment and the complexity of changing gear ratios.

It is particularly suitable for vehicles that require rapid adjustment of the final drive ratio depending on track characteristics, enabling teams to optimise the vehicle’s acceleration characteristics and control wheel speed in the shortest possible time.

Thanks to the use of high-quality alloy steel and precision machining techniques, it ensures smooth and reliable power distribution, whilst offering excellent durability and quiet operation.

The accompanying diagrams show the available gear ratio combinations.

The set includes 2 sets of gears, allowing for 4 different gear ratios.

Gear ratios included in the set:

• 25T / 19T, giving gear ratios of 3.13 and 5.42
• 23T / 21T, giving gear ratios of 3.76 and 4.52
