Bilstein B8 Control Arms are a direct-fit upgrade for the factory upper control arms on the Lexus GX460/GX470, Toyota 4Runner, and FJ Cruiser. They correct caster alignment for better straight-line stability on lifted suspensions, and improved pivot angles increase wheel travel while reducing stress on the joints. Built from black powder-coated 4130 chromoly tubular steel, with greasable polyurethane bushings and heavy-duty ball joints. Includes hardware and instructions; compatible with all Bilstein shocks and coilovers.
