HD Gasser Straight Axle Chevy Spindle/Brake Kit 56-1/2 Hub-to-Hub

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.

• 48 Inch

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

• Recommended for off-road / drag race applications
