1940-1946 Chevy Pick-up Truck Crossmember Kit Installation Instructions

Truck Crossmember Kit installation for Chevrolet Pick-up
1. Start by supporting the truck on 4 jack stands. The truck should be sitting at approximately the same angle as it does on the ground or slightly lower in front.
2. Remove all the old suspension components from the frame. The front spring shackle mounts riveted in the frame are used for a measuring point. The top of the frame rail should also be flattened in the area where it is turned up for the old steering box mount.
3. The radiator support crossmember will need to be modified next. Figure 1 shows the rear section that will need to be removed to provide clearance for the rack and pinion. The front section of the crossmember re- mains in place to support the radiator.

1955-1959 Chevy Pick-Up Crossmember Kit Installation

Remember the basic rule for a successful installation:
1. Start your installation by supporting the truck on 4 jack stands. The truck should be sitting on the approximate angle that it does on the ground, or slightly lower in front.
2. Begin by removing all the stock suspension components from the frame. The front crossmember should be left in place.
3. Boxing the rails is next. The flange on the left rail should be flattened where the old steering box was mounted and made straight and true. The boxing plates are to stand square on the lower rail flange. The frame rail top edges should be ground straight so the boxing plates fit tight to the rail edges. Do not grind too much off the rails. The boxing plates are then clamped in place, with the front end of the plates against the back of the stock crossmember. Weld in short sections at a time in alternating locations to minimize warpage. It is also a good idea to clamp a bar across the rails to hold them in place during welding. Grind smooth when done.
