Q & A

What's in the Box

Universal rear sway bar fits frame up to 45" wide, which makes it ideal for many 1928-1948 street rod applications. Both the 1-1/4" diameter shaft and the 2" O.D. weld-in frame tube can be shortened for narrower frames. The billet aluminum arms are not splined - they are held on by drilling the shaft and inserting a bolt all the way through the end of the shaft.

Includes bushings, 3/8" adjustable rod ends and all hardware. Welding required.


  • Tube Diameter:  2" O.D.
