Product details
UMI Performance solid sway bars are designed to reduce body roll, understeer and increase cornering capabilities resulting in a more balanced suspension. The 1.250” front sway bar is more rigid than the factory 7/8” front sway bar and comes complete with new high quality end links and greaseable sway bar bushings. The rear sway bar is 1” solid and is supplied with new grade 8 mounting hardware. UMI Performance sway bars are manufactured from 4140 chromoly steel and formed as one piece to ensure maximum strength and performance. The rear sway bar is heat treated to maintain longer memory than a cold bent bar while the front sway bar is CNC bent for a precision fit. Kit is available powder coated bright red or gloss black for a durable long lasting finish. UMI Performance solid sway bars reduce body roll and improve cornering. Made from 4140 chrome moly steel, the 1.250” front and 1” rear bars include greaseable bushings, end links, and Grade 8 hardware. Available in red or black powder coat.
