SPL Rear Knuckle Monoball Bushing Set for GT1R 15″ drag spindle. This kit will only work with the GT1R small rear brake kit.
Made in the USA.
This monoball set is engineered exclusively for the GT1R 15-inch drag spindle conversion. It must be paired with the GT1R small rear brake kit to function correctly.
Rubber bushings deflect under load, causing alignment changes. Monoballs eliminate this deflection, ensuring precise suspension geometry and consistent traction during high-power drag launches.
No. These bushings are part of a specialized 15-inch wheel conversion package. They are not compatible with standard knuckles or large factory Brembo brake calipers.
While durable, spherical bearings transmit more noise, vibration, and harshness (NVH) than rubber. They are race-oriented components designed for performance over comfort.
These bushings are proudly Made in the USA by SPL Parts. They are machined to aerospace tolerances to ensure they withstand the abuse of competitive drag racing.
