Lowering a torsion-bar truck
On torsion-bar trucks, the front ride height is set by the key at the back of the torsion bar. Drop keys have a different index, so you can turn the adjuster down past the stock limit and lower the front 1-3" with adjustable height.
- Pair with drop shackles or hangers for a matching rear drop.
- Use drop shocks for 2"+ drops.
- Trim bump stops or add low-profile bump stops.
- Always get an alignment after adjusting.
Lowering Torsion Keys and Drop Keys FAQ
How do I know if my truck has torsion bars?
Look under the front for long bars running from the lower control arms back to a crossmember. Many 2WD and 4WD GM trucks from 1988-2006, and many 4WD Ford and Dodge trucks, use them.
Are lowering torsion keys adjustable?
Yes. You set the height with the adjuster bolt, usually anywhere in a 1-3" range.
Do torsion keys ride rough?
They reduce downward travel, so pair them with drop shocks and don't max them out for the best ride.
