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.
