What to know before buying
ReadyLIFT 69-3920 is the useful premium comparison beside 66-3921 because it is a different kit family, not a duplicate seller row. The buyer is comparing a front-and-rear SST lift with upper control arms against a front-only level and a budget spacer. Amazon and Walmart currently sit well below the direct reference price, while ReadyLIFT direct and eBay preserve fitment, manual, MPN, and seller-quality context. Keep the recommendation careful: this product should appear for Trail Boss and AT4 shoppers who want the added rear-block package and can pass the late-model U-bolt, mono-leaf, tire, wheel, alignment, headlamp, and ADAS checks before checkout.

Use ReadyLIFT direct as the fitment authority; it describes the kit as Trail Boss/AT4-specific, excludes AT4X/ZR2, and calls for alignment and headlamp aim after install.

Why we carry it
This sits at the premium end among similar leveling kits products, with checked pricing near the top of the $69.95 to $529.88 range and 4 seller options for this product. The expensive option earns a closer look when it brings control arms, better shocks or coilovers, clearer instructions, or a wider margin for ride quality and long-term wear. If the goal is simply to get a compatible part for less, compare it against ReadyLIFT 66-3921 1.75 inch GM AT4 and Trail Boss leveling kit before paying the premium.
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 Amazon, Walmart, eBay, and ReadyLIFT direct while checking exact SKU, U-bolt notes, tire guidance, and installer requirements.

Use these as quick checks before paying more or chasing the cheapest listing. Some cards are category benchmarks when same-vehicle choices are thin; the right answer still depends on the exact truck, seller fitment note, and install plan.

Specs to verify
Front lift
2 inches front with 1 inch rear package
Install type
SST lift kit with upper control arms, front spacers, rear blocks, and U-bolt checks
Core fitment
2019-2025 GM AT4 and Silverado Trail Boss factory-lift 1500 trucks in current public evidence
Tire guidance
Use ReadyLIFT direct and installation notes for tire-size, wheel-offset, and test-fit limits
Install caution
Certified mechanic recommended; alignment, headlamp aim, ADAS checks, U-bolt selection, and hardware recheck remain required
Compatibility by model year
Year range is only the first pass. The final answer still depends on model, trim, body style, drive, suspension package, and current seller fitment data.
2019-2025 Silverado 1500 Trail Boss, excluding ZR2
Use on Silverado 1500 Trail Boss factory-lift trucks when the current ReadyLIFT or seller selector confirms the exact year, cab, drive, trim, and rear-block hardware. This is not a normal-height Silverado spacer kit.
Checked trim pages
LT Trail Boss 4x4 Crew Cab
Trim and body style
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.
Engine and powertrain
ReadyLIFT and marketplace fitment rows are not engine-only for this route; final checkout should still confirm the buyer's 2.7L, 3.0L Duramax, 5.3L, or 6.2L configuration in the live selector.
Model-year notes
The 2019 Silverado/Sierra redesign created a distinct fourth-generation GM 1500 platform. Keep this product on factory-lift Trail Boss/AT4 applications and do not reuse older K2, LD/Limited, ZR2, or normal-height kit assumptions.
What to double-check
The public evidence set is strongest through 2025 because current ReadyLIFT and seller pages vary between 2019-2024 and 2019-2025 wording; refresh before carrying it into 2026.
Included
- Silverado 1500 Trail Boss factory-lift candidates
- Buyers comparing a front-and-rear SST lift package
- Trail Boss tire planning after ReadyLIFT and installer checks agree
Excluded
- Silverado ZR2
- Normal-height Silverado trims using different leveling geometry
- Aftermarket lift struts or additional lift components stacked with this kit
Check before buying
- Exact 69-3920 SKU and UPC 804879610472
- Trail Boss trim and current seller selector
- U-bolt or mono-leaf note, wheel/tire test fit, alignment, headlamp aim, ADAS calibration, and recheck
2019-2025 Sierra 1500 AT4, excluding AT4X
ReadyLIFT direct names GM AT4 trucks for 69-3920, but this branch promotes the checked Silverado Trail Boss route first. Add a public Sierra AT4 route only after seller pages and vehicle copy are checked without duplicating identical seller rows.
Checked trim pages
AT4 Crew Cab 4x4
Trim and body style
AT4 factory-lift trucks are inside the official product family, while AT4X, Denali adaptive ride paths, normal-height Sierra trims, older-body overlap, and aftermarket lift systems need separate checks.
Engine and powertrain
Treat engine coverage as selector-confirmed rather than engine-specific until a Sierra AT4 public route captures current seller tables for the buyer's exact engine.
Model-year notes
Keep Sierra AT4 compatibility tied to the 2019-2025 public evidence set and factory-lift suspension. It is not evidence for older K2 trucks, LD/Limited models, AT4X, or normal-height Sierra kits.
What to double-check
ReadyLIFT direct carries AT4 wording while marketplace rows can lag or omit GMC language, so Sierra promotion should refresh direct, seller, and installer evidence together.
Included
- Sierra 1500 AT4 factory-lift candidates after live seller confirmation
- AT4 shoppers comparing front-and-rear SST lift kits
- AT4 tire planning after ReadyLIFT and installer checks agree
Excluded
- Sierra AT4X
- Normal-height Sierra trims
- Aftermarket lift struts or additional lift systems stacked with this kit
Check before buying
- Exact Sierra AT4 trim and current seller selector
- AT4X/adaptive-ride/lift-system exclusions
- U-bolt, wheel/tire, alignment, headlamp, ADAS, and recheck workflow
