SPL Parts Rear Upper Control Arms (RUA) provide the expanded rear camber adjustment range necessary for lowered BMW F2X and F3X chassis. Factory eccentric washers are often insufficient for reaching proper alignment specifications on performance-oriented or lowered vehicles. These links offer the precision required for both dedicated track use and high-performance street applications.

The center links and clevises are constructed from gun-drilled 2024 Aluminum for maximum strength and minimal unsprung weight, secured with Blue Anodized Titanium socket head cap screws. SPL's 360-degree rotating clamp system allows for quick and easy alignment changes using a 3/16" Allen key, eliminating the need to fumble with traditional jam nuts while trying to maintain bearing orientation.

To ensure consistent handling, these arms feature FK Spherical Rod Ends with a chemically bonded PTFE/Teflon liner. These eliminate the deflection found in factory rubber bushings, reducing alignment changes during hard cornering, acceleration, and braking. The liner provides quiet, low-friction operation with high load capacity across a wide temperature range.
