SPL Pro Suspension SPL RKB F3X Rear Traction Arm Knuckle Bushings

The SPL RKB F3X Rear Traction Arm Knuckle Bushings replace the rubber factory bushing attaching the lower control arm to the knuckle with a low friction teflon-lined spherical bearing. Replacing the OEM component with this bushing will allow 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 insure proper fitment
• Sold as a pair and made in the USA
• Replaces BMW Part Number 3336792551

These precision-engineered bushings eliminate the mushy feel of factory rubber bushings, providing improved suspension response and feedback during spirited driving. The self-lubricating teflon liner ensures long-lasting performance while the oversized FK bearings help maintain reasonable noise, vibration, and harshness levels compared to smaller alternatives.
