Item Details

37-41 Ford Spindles, Specify bolt pattern,
46" Wide axle - 54 1/4" hub to hub.

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.

Part # 9103546 King pins are strong enough for almost any load. Many customers have full sized cars such as Tri-5 Chevies with blown big blocks. The spindles are forged for utmost strength and again handle almost any load. If planning on 45 degree wheel stands and dropping it on the front end the weakest link would be the axle tube itself which may bend under those extreme situations.
