Developed in response to a strong request from GRK RACING driver TAKU, the highly anticipated “T Knuckle” has arrived.
Proven in competition with a perfect win in both Solo and Chase runs, the T Knuckle was developed to maximize front-end tracing performance while maintaining the high-speed characteristics that define TAKU’s driving style.
It can also be installed on the GS2MOD with an easy setup,* making it capable of delivering excellent driving performance across a wide range of configurations.
From top-level competition to beginner setups, the T Knuckle is a versatile knuckle designed to accommodate a wide range of driving styles and skill levels.
Important Notes
When upgrading from the Ver.Y or V1 Knuckle: When using this knuckle with our axles (R31S024 / R31S064 / R31S131), clearance adjustment is required.
For example, adding a 1mm GRK-R Replacement Idler Spacer (R31S123) may be necessary to achieve proper clearance.
When upgrading from the standard plastic knuckle: When replacing the standard plastic knuckle with the T Knuckle, 1050 bearings with a 4mm thickness must be purchased separately.
