Description

The UMI Performance 3665-B is a 1-inch solid rear sway bar designed for 1965-1970 Chevy B-Body vehicles. It is manufactured from heat-treated high carbon steel to enhance performance by reducing body roll and understeer, thereby improving cornering capabilities and suspension balance.

This sway bar includes Grade 8 hardware for straightforward installation. It is compatible with factory control arms that have sway bar holes and with UMI Performance lower control arms part #3655. It is intended for use exclusively with stock GM axle housings and is not compatible with Ford 9-inch axle housings.
