Four bar suspensions allow your front axle to travel freely, thus providing better ride and handling than traditional radius rods. Plus, their polished stainless construction will keep your front end glowing forever! Speedway kits feature bat wings and tapped bar ends, complete with nylon rod ends. For axles with 2" or 2-1/4" boss - use spacers 916-35003 if necessary.

We strongly reccommend the use of a front panhard bar with four bar front suspensions. Four bar suspensions increase suspension travel over original wishbones or radius rods, which increases the need for side-to-side axle control. If using a Vega cross steering system, the panhard bar becomes mandatory as any side-to-side movement will cause bump steer.
