Part Number: 66-30200

  • 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
  • Silverado and Sierra have different fender well opening sizes - some minor trimming my be required depending on 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 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.
