The REKUDO Front Sway Bar for your 1970-1981 GM F-body is suitable for street driving, autocross and weekend warrior track days. The 1-3/8" (1.375") diameter cuts body roll and stiffens up the front suspension. Polyurethane frame and end link bushings are used as an upgrade from 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" wall thickness and is tubular to reduce weight. It comes in a black powder coated finish and bolts in place of a factory Chevy Camaro or Pontiac Firebird anti-roll (stabilizer) bar. Installation hardware is included.
