ReadyLIFT 69-3920 2 inch front with 1 inch rear GM AT4 and Trail Boss SST lift kit

Is the ReadyLIFT 69-3920 2 inch front with 1 inch rear GM AT4 and Trail Boss SST lift kit the leveling kits pick here, or just one of three?

Best fit for factory-lift GM 1500 shoppers who want a front-and-rear SST lift package rather than a front-only spacer level.

The ReadyLIFT 69-3920 2 inch front with 1 inch rear GM AT4 and Trail Boss SST lift kit is on this shortlist for a specific truck and use, not because it beats the Rough Country leveling and lift kit and the ReadyLIFT SST leveling and lift kit on every line. The rows below keep included hardware, the fitment, and install effort in view before any seller price, so the trade stays yours to make.

Verify first

Use on Silverado 1500 Trail Boss factory-lift trucks when the current ReadyLIFT or seller fitment tool confirms the exact year, cab, drive, trim, and rear-block hardware. This is not a normal-height Silverado spacer kit.

Choose it, pass, or verify

A higher-content ReadyLIFT SST kit for Trail Boss and AT4 shoppers who want more than a front-only level and can verify rear-block and late-model hardware notes.

Choose it if

  • Best fit for factory-lift GM 1500 shoppers who want a front-and-rear SST lift package rather than a front-only spacer level.
  • Use the narrower current 2019-2025 public range until ReadyLIFT and seller tables are refreshed for later model-year claims.
  • Compare Walmart, eBay, and ReadyLIFT direct while checking exact SKU, U-bolt notes, tire guidance, and installer requirements.
  • Use on Silverado 1500 Trail Boss factory-lift trucks when the current ReadyLIFT or seller fitment tool confirms the exact year, cab, drive, trim, and rear-block hardware. This is not a normal-height Silverado spacer kit.

Pass if

  • The ReadyLIFT 69-3920 2 inch front with 1 inch rear GM AT4 and Trail Boss SST lift kit is not the right choice when your truck falls outside 2019-2025 Chevrolet Silverado 1500 Trail Boss factory-lift trucks, or its trim, engine, and package cannot be matched to the documented application.
  • Pass when this exclusion applies: Silverado ZR2
  • Choose another kit when the truck needs more height, rear-load support, adjustable damping, or hardware this package does not include.

Verify

  • Exact 69-3920 SKU and UPC 804879610472
  • Trail Boss trim and current seller fitment tool
  • U-bolt or mono-leaf note, wheel/tire test fit, alignment, headlamp aim, ADAS calibration, and recheck
  • The checked public route is a 2024 LT Trail Boss 4x4 Crew Cab. Custom Trail Boss, other cabs, late-model hardware changes, older overlapping body styles, dealer-lift trucks, aftermarket lifts, and ZR2 need current seller and installer checks before inheriting this answer.
