  • 48 inch

Note: Wilwood brakes increase hub-to-hub width by 1/2".

-Wilwood brake kit will not work with ET gasser wheel 91058673. The Wilwood kit only comes with 1/2" studs for both the 5x4.5 and 5x4.75 bolt pattern. If you would like to use the 5x4.75 pattern, you will need to source a set of screw in 7/16" wheel studs.

Features

  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.
