The front suspension on a Chevrolet Silverado 2500HD sits slightly lower than the rear of the truck. This is to ensure that when the bed of the truck is weighed down, it doesn't sag lower than the front end and make the truck difficult to drive. But if you want the truck to sit higher in the front, you can install a torsion key leveling kit to the front end to raise the suspension anywhere from 1-1/2 to 2-1/2 inches. This takes about four hours to do.
Things You'll Need
- Jack stands
- 1/2-inch ratchet and socket set
- Torsion key leveling kit
- Torsion bar removal tool
- Paint marker
Park the truck and put on the parking brake. Lift the front end on the 2500HD with the jack and put jack stands underneath the frame.
Locate the torsion bar cross member, which runs the width of the truck and sits under the cab. Install the torsion bar removal tool onto the torsion bar key, just outside of the torsion bar adjuster bolt on the cross member. Tighten the tool with the 1/2-inch ratchet and socket.
Make a vertical line across the torsion key and the torsion bar with the paint marker. Remove the torsion bar bolt with the 1/2-inch ratchet and socket. Slowly loosen the torsion bar removal tool with the 1/2-inch ratchet and socket. Push the torsion bar towards the back of the truck to remove the bar from the lower control arm, then push it forward and under the lower control arm to remove the torsion key from the torsion bar.
Transfer the mark you made in step 3 to the replacement torsion key in the torsion key leveling kit using a paint marker. Install the replacement torsion key onto the torsion bar, lining up the marks in the process.
Install the torsion bar removal tool and tighten it in place with the 1/2-inch ratchet and socket. Reinstall the torsion bar bolt with the 1/2-inch ratchet and socket, then remove the torsion bar tool with the 1/2-inch ratchet and socket. Lower the truck off of the jack stands using a jack.
