Description

ReadyLIFT 66-3921 1.75" Leveling Kit for 2019-2026 GMC AT4 and Chevy Trail Boss

  • 1.75" front leveling lift engineered to restore balance on 2019–2026 GM 1500 pickups without interfering with factory strut geometry or causing binding with the control arm ball joint and lower CV/axle components.
  • Includes tubular upper control arms with corrected ball joint cup angles and heavy-duty replaceable ball joints for consistent alignment and long-lasting performance.
  • Terrain Control Technology (TCT) maintenance-free pivot bushings with side-biter washers to improve alignment retention.
  • Similar to ReadyLIFT’s proven 66-3086 design, offering a trusted upgrade path for retrofitting with modern GM trucks without the typical fitment issues.
  • Max tire size guidance: AT4 accepts up to 275/60-20 on 20x9 wheels with 0 offset; Trail Boss accepts up to 295/65-20 on 20x9 wheels with 0 offset.
  • Note on compatibility: Not compatible with Sierra AT4X or Silverado ZR2 Edition.
