(R31S064)GRK RWD Lightweight Front Axle

Introducing a new lightweight axle shaft developed for GRKRWD!

 

This hard-anodized aluminum product is significantly lighter than the standard steel axle for GRK4/GRK5. The

 

newly designed axle shaft features a repositioned hub pin mounting hole to minimize any backlash that can cause rotational resistance.

 

While compatible with standard hexagonal hubs, pairing it with the GRK4/GRK5 aluminum brake rotor (R31W339) offers both the lighter axle's weight for quicker kickoff and the inertia of the brake rotor for smoother rolling.

New lightweight axle shaft developed for GRKRWD!

 

By making this hard anodized product made of aluminum, it has achieved a significant weight reduction compared to the GRK4/GRK5 standard steel product.

 

By changing the position of the hub pin mounting hole, it is a newly designed axle shaft that minimizes mounting play that can cause resistance during rotation.

 

Although it is compatible with general hexagonal hubs, by combining with GRK4/GRK5 aluminum brake rotor (R31W339), you can expect both speed of kicking due to the lightness of the axle body and rolling due to the inertia of the brake rotor.
