ARR21800-LCA Installation Instructions
1. Raise the vehicle to a safe and comfortable working height. Let the rear suspension hang
freely.
2. Remove the bed.
3. Raise the axle a couple inches and support it so that it cannot rotate. Remove the trailing
arms, coil springs, shock absorbers, and panhard bar. Refer to the factory service manual
for proper disassembly procedures. Note: This kit is designed for use with a 1-piece drive
shaft.
4. The factory trailing arm frame
cross member will be replaced with
the tubular one supplied. To remove
the factory cross member, the rivets
must be removed. The easiest
method is to chisel them off with an
air hammer. Then use a hammer
and punch to drive the rivets out.
Note: On each side there is one rivet
in front of the cross member and one
behind that must also be removed for
the new cross member.
5. Install the new cross member with
the trailing arm flanges towards the
rear. The cross member is bolted to
the bottom side of the frame rails
using 10 - 7/16” x 1” bolts, 10 - 7/16”
Nylok nuts and 20 - 7/16” flat
washers. It may be necessary to
enlarge some of the holes with a
7/16” bit.
Note: On short bed trucks you may
have to raise the cab to remove the
factory cross member.
