GRK5 Aluminum Gearbox

The aluminum gearbox used on the GRK5 is now available as an optional part for other GRK models.

• Optimized design:

This model adopts a more robust design, inspired by differential cars in real cars. Its weight has been increased compared to previous aluminum gearboxes (R31W279/R31S310) to improve load balance on the rear axle, essential for a Drift RWD machine.

• Improved material:

To replace the resin gearboxes of the series GRK Global, this aluminum component improves overall traction and performance, even on vehicles equipped with traditional aluminum versions such as the GRK4.
