The Stage 1 "Basic" Leveling Shock Extender is a simple fix to the first problem faced when adjusting your torsion bars on a Chevy/GM HD to add a mild amount of lift, commonly known as "Leveling" or "Cranking". If you are looking for a slight gain in height and need to do it on a budget, suggests you simply add these shock extenders and use with the adjustability in your factory torsion keys.

  • Complete hardware and instructions

Features & Benefits:

  • Allows a customer to level their truck stance without over-extending the factory shock.
  • DIY friendly


  • Over-Cranking the suspension will reduce the ride height drop travel. This will affect the ride quality and is not recommended.
  • The distance between the upper control arm and frame drop stop should be NO-LESS than 5/8" distance at ride height.
  • With this system you will be allowed to raise the front of a single wheel HD truck close to a level stance, without hindering the ride quality too much.


  • DIYer Install time including adjusting ride height - 45 min-1.0 Hours
  • Have the vehicle professionally aligned after installation.
