Info

One for show, One for go. Speedway brings to market a heavier duty application of their popular gasser axle selection. When your gasser tribute car has gotten a bit out of hand on your quarter-mile slips, you may want the added assurance that a stronger 3/8” thick wall axle provides. These axles are ideal for serious drag cars and heavier vehicle applications like 1955+ trucks and 1955-63 Chevy’s. A 28% improvement in strength will give you the added insurance that when the light turns green you can hang your hoops without worry.

These kits include our gasser straight front axle, semi-elliptical springs, spindles, king pins, steering arms, tierod kit, brake kit, and hardware. Choose either 5 on 4-1/2" or 5 on 4-3/4" bolt pattern with standard brake kit or Wilwood brake kit. Standard brake kits use new rotors and GM metric style calipers. Wilwood brake kit includes dual-drilled hub. Brake lines not included. Shocks not included, but shock mounts are included. Assembly required.

  • 50 Inch

Note: Wilwood brakes increase hub-to-hub width by 1".

  • Recommended for off-road / drag race applications

Item Details

49-54 Chevy Spindles w/ o/e style rotors/calipers, Specify bolt pattern,
44" Wide axle - 52 1/2" hub to hub.

46" Wide axle - 54 1/2" hub to hub.

48" Wide axle - 56 1/2" hub to hub.

50" Wide axle - 58 1/2" hub to hub.

Wilwood brake kit adds 1" to hub to hub widths above.

 

Notes

  1. If using steel wheels with Wilwood kit, you will also need to purchase (2) steel shims part 835-3007500. These shims will prevent steel wheels from galling the aluminum hub.
  2. Rubber brake hoses generally cannot be adapted to Wilwood calipers. The caliper inlet fitting is a 1/8-27 NPT. The preferred method is to use steel adapter fittings at the caliper, either straight, 45 or 90 degree and enough steel braided line to allow for full suspension travel and turning radius, lock to lock.
