The ReadyLIFT 8" Lift Kit gives the truck a tall stance and room for a large tire package. Every major component is designed for this truck's chassis and suspension layout. ReadyLIFT kit 44-3985 is engineered for the 2019-2022 Chevrolet Silverado 1500, Silverado 1500 LD and Silverado 1500 LTD and GMC Sierra 1500.
Wheels, tires, alignment, headlamp aiming, ADAS recalibration and any trimming labor are not included.
Features
Tall stance, big tires
A big lift raises the truck well beyond leveling height and clears a large tire package. ReadyLIFT lists the tested tire size for each kit.
Geometry relocated, not stretched
Instead of only spacing parts apart, the kit moves suspension mounting points down with heavy-duty brackets, crossmembers, knuckles or springs to keep angles workable.
Heavy-duty steel construction
Brackets and crossmembers are fabricated from heavy steel plate sized for the loads of a lifted truck on large tires.
Driveline and steering addressed
Big lifts change driveline and steering angles, so ReadyLIFT includes the drops, spacers or brackets this platform needs at the new height.
Complete system per truck
Each kit is engineered around one truck platform and ships with the components listed in its kit contents.

Installation
Type: full suspension lift · Install: involved, per-vehicle install sheet · Afterward: alignment, headlamp aim, ADAS check
This kit installs using the steps in ReadyLIFT's instructions for this truck, including any trimming the instructions call for. Plan on a wheel alignment after installation and have headlamp aim checked. Vehicles with camera, radar or sonar driver-assistance systems need those systems checked and recalibrated, which can require dealer tools. ReadyLIFT recommends installation by a certified mechanic and says to read the full instructions before starting. Tire sizes are ReadyLIFT guidance based on specific wheel and tire brands, so test fit every combination. Larger E-rated tires have stiffer sidewalls than stock C-rated tires and can make the ride feel firmer.
ReadyLIFT estimates about 11 hours for this kit, give or take 1 hour, not counting the alignment or mounting wheels and tires.

About ReadyLIFT
ReadyLIFT Suspension started in 2006 with one goal: give truck and SUV owners more tire clearance and a better stance while keeping the ride and handling their vehicle had from the factory.
What began as a practical option to traditional big lifts now spans front leveling kits, SST mild lifts, full big lift systems, premium coilover packages, upper control arms and Falcon shocks for popular trucks and SUVs.
Wheel Pros bought ReadyLIFT in 2018, and in August 2026 the brand joined Bestop Premium Accessories Group, which plans continued investment in engineering, product development, manufacturing and customer support.
