2020-2025 Duramax 2" Front Torsion Key Leveling Kit (66-30200)

Description

Fits

Year Make Model
2020-2025 GMC/ Chevrolet HD 6.6L Duramax 

 

One of the best, most budget-friendly leveling solutions to come from ReadyLift; along with the new look, GM also updated the torsion bar system. These keys are specially designed for function and proper fitment on the 2020+ Duramax suspension design, fully adjustable to provide a comfortable ride and allow enough clearance for 35" tires.

Part Number: 66-30200

Features
  • 2 Torsion Keys
  • Model-specific indexing
  • Does not affect OEM ride quality
  • Budget-friendly

Tire Fitment: 

  • 20x9 +18 or 0 offset - 35x12.50" tire
  • Trimming may be required with some tire styles on 20x9 0 offset - 35x12.50 or 325/60R20
Notes
  • Silverado and Sierra have different fender-well opening sizes - some minor trimming may be required depending on the true tire size and design.
  • When setting the torsion key adjustment bolt, do not exceed 26” from the wheel center to the fender edge. Exceeding this will overlift the vehicle, creating a top-off condition, meaning the suspension has little to no down travel. The result is poor ride quality and premature wear of components.
  • Some fender well variance may be experienced between the Silverado and Sierra models.  66-30200 works with trucks equipped with either the OE #84461807 or OE #84634344 factory torsion keys and requires ReadyLIFT torsion key unloading tool 66-7822B or similar for installation. 
  • Does not work with AT4X or ZR2 models.
