Rear lift and alignment
When the front is raised with torsion keys, the rear is usually lifted too so the truck sits level. The rear add-a-leaf changes the leaf pack, so the rear springs carry load differently after installation. Look at the shackles, U-bolts and leaf clamps while the rear is apart, and replace any worn bushings before reassembly.
Because the front torsion bars are adjusted, the wheel alignment will change. Check the steering for play and inspect the front shocks, since they work at a different angle after the change. Re-tighten all fasteners after the first few trail runs or highway trips, and check tire pressure against the load the truck is carrying.
- Inspect shackles and U-bolts
- Check rear leaf clamps and bushings
- Verify alignment after the torsion key change
