Product details
Our beefy 1" solid rear sway bar is designed to reduce body roll, understeer and increase cornering capabilities resulting in a more balanced suspension. This rear sway bar also works to keep your vehicle level and straight during those hard launches. Our sway bar is manufactured from 1" solid 4140 CrMo steel, heat treated and formed as one piece to ensure maximum strength and performance. The hot forming and heat treating process allows the bar to maintain its shape and memory longer than a cold bent bar. Rear sway bar includes new Grade 8 hardware to complete the installation. The bar is available powder coated Bright Red or Gloss Black. Fitment Note: When installing on a after-market Ford 9" the drain plug guard may create a fitment issue. 4034 - 1964-1972 GM A-Body 1" Solid CrMo Rear Sway Bar
