ReadyLIFT 66-3921 1.75" Leveling Kit

The ReadyLIFT 66-3921 is a 1.75" leveling kit engineered for GM 1500 AT4 and Trail Boss trucks. It provides the required lift while maintaining proper strut geometry and clearances on trucks that already have a factory 2" front lift. The kit is designed to avoid binding and contact issues that can occur when combining traditional leveling components with the factory lifted AT4/Trail Boss suspension.

Includes tubular upper control arms with corrected ball joint cup angles.
Heavy-duty, replaceable ball joints for improved durability.
Terrain Control Technology (TCT) pivot bushings — maintenance-free with side-biter washers to improve alignment retention.
Provides required lift without interfering with factory strut/CV axle assemblies or control arm geometry.

*Note: The AT4 and Trail Boss have different front fender opening designs and do not accept the same maximum tire sizes. This kit is not compatible with Sierra AT4X or Silverado ZR2 editions. Refer to vehicle specifications for final tire and wheel fitment.

Applications	Front	Rear
AT4	Max tire 275/60-20	20x9 0 offset wheel
Trail Boss	Max tire 295/65-20	20x9 0 offset wheel
