SPL Parts FKS Series Rear Knuckle Monoball Bushings (RKB) for Camaro / Cadillac ATS

Upgrade your Camaro or ATS with SPL Parts Rear Knuckle Monoball Bushings, designed to eliminate unwanted bushing flex and improve suspension precision. These bushings replace the factory rubber units with low-friction spherical bearings, maintaining ideal suspension geometry under load for sharper handling and better driver feedback — without significantly increasing NVH.

The factory rubber bushings allow unwanted deflection during hard launches or cornering, resulting in unpredictable toe and camber changes, wheel hop, and reduced stability. SPL’s Monoball Bushings eliminate these issues, ensuring consistent and repeatable performance on track or street.

Key Features:

• Replaces soft OEM rubber bushings with precision FK spherical bearings

• Eliminates bushing flex and suspension bind for improved geometry control

• CNC-machined T6061 aluminum bearing shells (machined to 1/1000th inch) for perfect fitment

• Self-lubricating Teflon-lined bearings for long life and quiet operation

• Reduces wheel hop, enhances stability, and sharpens handling response

• Sold as a complete kit for one car

• Made in the USA
