Multi-Use Ver.2 rear knuckles

The GRK Multi-Use Rear Knuckle Ver.2 are an evolution of the R31S334 rear knuckles, with a revised design to meet current setups while providing more lightness and rigidity.

Manufacturing is now carried out in Japan to improve machining and assembly precision.

New positioning systems have been integrated into highly stressed areas, particularly at the extension plate and thelower arm adapter. This design allows for more precise assembly and makes it easier to achieve repeatable geometry settings.

The product is sold as a left and right set.
