The ReadyLIFT 1.75" Leveling Kit (part 66-3921) is made for factory-lifted 2019-2026 GMC Sierra 1500 AT4 and Chevy Silverado 1500 Trail Boss trucks. Because the factory upper control arms run out of range when these trucks are lifted further, the kit includes tubular upper control arms along with billet strut spacers to level the truck without conflicting with factory strut geometry.

Part number: ReadyLIFT 66-3921

Key features

  • 1.75" of front lift for factory-lifted AT4 and Trail Boss trucks
  • DOM tube steel upper control arms with corrected ball joint cup angles and heavy-duty replaceable 1-ton ball joints
  • Terrain Control Technology (TCT) maintenance-free pivot bushings with side-biter washers to help hold alignment
  • CNC-machined billet aluminum top and bottom strut spacers
  • Avoids ball joint binding and strut/CV axle contact issues of traditional leveling kits on these trucks

What's included

  • Two tubular steel upper control arms with TCT pivot bushings and 1-ton ball joints
  • CNC-machined billet aluminum top and bottom strut spacers

Fitment

  • 2019-2026 GMC Sierra 1500 AT4
  • 2019-2026 Chevy Silverado 1500 Trail Boss
  • Not compatible with Sierra AT4X or Silverado ZR2

Tire fitment

  • AT4 and Trail Boss do not fit the same tire size because of different front fender openings
  • AT4: 275/60-20 maximum on a 20x9 wheel with 0 offset
  • Trail Boss: 295/65-20 maximum on a 20x9 wheel with 0 offset
  • Trail Boss on factory wheels: up to 285/75R18 with wheel spacers
  • ReadyLIFT bases its wheel and tire recommendations on specific wheel and tire brands, and sizes vary by manufacturer, so test-fit every wheel and tire combination before installation.

Install notes

  • Estimated installation time: 3.5 hours +/- 0.5 hours (excludes alignment and wheel/tire assembly).
  • Read the instructions completely before starting. ReadyLIFT recommends installation by a certified mechanic.
