UMI Performance solid sway bars are designed to reduce body roll and understeer and to increase cornering capability for a more balanced suspension. The 1.250 inch front bar is more rigid than the factory 7/8 inch front bar and comes complete with new high-quality end links and greaseable sway bar bushings. The 1 inch solid rear bar is supplied with new grade 8 mounting hardware. Both bars are manufactured from 4140 chromoly steel and formed as one piece for maximum strength. The rear bar is heat treated to hold its memory longer than a cold-bent bar, while the front bar is CNC bent for a precise fit. The kit is offered in bright red or gloss black powder coat for a durable, long-lasting finish. UMI Performance manufactures this kit in the USA.
