Product Description
The B-body's rear sway bar options from the factory were never built with performance in mind, leaving these full-size GM sedans with more body roll and understeer than their chassis can really handle. The UMI 3634-B replaces it with a beefy 1.125" solid steel bar, heat-treated and formed as one piece, that noticeably tightens up cornering and keeps the car flatter and more composed under hard driving.
It bolts directly to UMI's own control arms using GM's original mounting location, and pairs with the optional 3636 bracket kit if you're running factory arms without built-in sway bar provisions. It's a straightforward handling upgrade for Caprice, LeSabre, Roadmaster, Bonneville, and Catalina owners - just note it's not compatible with wagon body styles.
