SPL Pro Suspension SPL RLCB E9X Rear Lower Control Arm Knuckle Bushing

The SPL RLCB E9X Rear Lower Control Arm Knuckle Bushing replaces the rubber factory bushing attaching the lower control arm to the knuckle with a low friction teflon-lined spherical bearing. This upgrade allows for less deflection under heavy load, and less bind as the arm travels through its suspension.

Key Features:

• Uses the largest possible FK bearing in this location for increased longevity and lower NVH
• Housing machined from 6061-T6 aluminum and CNC cut to +/- .001" tolerance to ensure proper fitment
• Sold as a pair
• Made in the USA
• Direct replacement for BMW part numbers 33326775552 and 33326756249

SPL Parts sources certified materials from the USA and utilizes CNC machining by experienced local machine shops to meet exacting tolerances. All parts are hand-fitted to ensure proper fit and smooth threading. These bushings provide improved handling performance and reduce deflection during aggressive driving while maintaining acceptable noise, vibration, and harshness levels.
