Product Details

This beefy 1” solid rear sway bar is designed to reduce body roll, understeer and increase cornering capabilities resulting in a more balanced suspension. Our sway bar is manufactured from 1” solid high carbon steel, heat treated and formed as one piece to ensure maximum strength and performance. Rear sway bar includes all new Grade 8 hardware to complete the installation. This item will work with the factory control arms that feature factory sway bar holes and the UMI Performance lower control arms, part # 3655. NOTE: The 3665 is intended for use only on stock GM axle housings. Interferes with Ford 9.
