GRK Lightweight Aluminum Knuckle Ver.HRP (Blue)

Following the popularity of the knuckle commonly known as the “Y Knuckle,” the next evolution has arrived: the GRK Lightweight Aluminum Knuckle Ver.HRP.

Developed under the supervision of HAYATO, its carefully refined geometry and setup specifications were developed specifically for today’s drift scene.

The goal was to achieve a precise and responsive steering feel, along with improved front-end tracing performance, suited to modern drift setups.

Available in Black, Purple, Red, and Blue.

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.

Bearing:
Please use 1050 bearings with a 4mm thickness.
