Are B8 Upper Control Arms Compatible with Non-BILSTEIN Shocks?

BILSTEIN's B8 Upper Control Arms (UCA) can be paired with other brand name shocks.

BILSTEIN B8 Upper Control Arms will work with other brand name direct fit replacement shocks and coilovers for trucks and SUVs. However, we recommend pairing them with BILSTEIN shocks and coilovers for optimum performance.

CAUTION: BILSTEIN Upper Control Arms are not compatible with lift spacers and may not be compatible with some aftermarket spindles. If using aftermarket spindles, installer must check clearance between control arm and spindle throughout full suspension travel. BILSTEIN is not responsible for any damages caused due to insufficient clearance with aftermarket spindles.


The kit contains a pair of control arms which correct the caster alignment for better straight line stability with lifted suspensions, and the improved pivot angles increase wheel travel and reduce stress on the joints. These strong black powder-coated 4130 chromoly steel arms are a tubular design which allows for more spring and shock clearance and feature greaseable polyurethane bushings and heavy duty ball joints for the ideal combination of ride quality and durability with minimal maintenance needed. They come with detailed instructions and all necessary hardware for easy installation and are compatible with all Bilstein shocks and coilover kits. All components are replaceable.
