Enhance the cornering performance and lateral stability of your GM B-Body with this UMI Performance 3634-B rear sway bar. Designed to significantly reduce body roll, this solid 1.125-inch diameter bar provides a flatter, more controlled handling experience during spirited driving. The bar is engineered to mount in the factory location, maintaining the suspension geometry as originally designed by GM.

Constructed for durability and performance, this sway bar features a black powder-coated finish to resist corrosion and includes high-quality mounting hardware for a straightforward installation. This bar is a direct bolt-on for vehicles equipped with UMI rear control arms; if you are utilizing factory control arms, the optional 3636 bracket kit is required for installation.
