The REKUDO Front Sway Bar is suitable for street driving, autocross, and weekend warrior track days. The 1-3/8-inch diameter reduces body roll and stiffens up the front suspension. Polyurethane frame and end link bushings are used as an upgrade over rubber, offering superior durability and function. Polyurethane bushings allow the bar to come into action immediately, unlike rubber bushings that must compress first before the bar becomes functional. No need for concerns about polyurethane squeaking. The frame bushings are easily greaseable via Zerk fittings in the bushing frame brackets.This cold-rolled carbon steel bar has a .156-inch wall thickness and is tubular to reduce weight. It comes in a black powder-coated finish and bolts in place of the factory anti-roll (stabilizer) bar. Installation hardware is included.
