ReadyLIFT AT4/Trail Boss Plus 2.0" SST Lift Kit for 2019-2024 GM 1500 4WD

The 69-3920 adds 2" of front lift to the 2" the GMC AT4 and Chevy Silverado Trail Boss already have from the factory. A traditional leveling kit causes problems on these trucks, such as binding of the factory control arm ball joint, so ReadyLIFT built this one specifically for them. See lift kits.

A CNC-machined billet aluminum top spacer and pre-load spacer work with heavy-duty tubular upper control arms that have 1-ton ball joints and TCT pivot bushings. The rear gets 3" OE-style cast iron lift blocks with new U-bolts. Browse full-size truck parts.

Why it works
Built for factory-lift trucksDesigned around the AT4 and Trail Boss factory 2" lift.
Billet spacersCNC-machined aluminum top mount and pre-load spacers.
Upper arm upgradeTubular arms with 1-ton ball joints and maintenance-free bushings.
Rear lift blocks3" OE-style cast iron blocks with longer U-bolts.
What's included
  • CNC machined billet aluminum top mount spacer and pre-load spacer
  • Tubular upper control arms with 1-ton ball joints and TCT pivot bushings
  • 3" tall OE-style cast iron lift blocks with longer U-bolts
