The ReadyLIFT 1.5" Leveling Kit raises the front end so the vehicle sits level instead of nose down. It is the simplest way to change the stance without lifting the rear. ReadyLIFT kit 66-39150 is engineered for the 2019-2026 Chevrolet Silverado 1500, Silverado 1500 LD, Silverado 1500 LTD, Suburban and Tahoe and GMC Sierra 1500 and Yukon.
Wheels, tires, alignment, headlamp aiming and ADAS recalibration are not included.
Features
Removes the factory rake Most vehicles leave the factory sitting lower in front. A leveling kit adds front height so the body sits even from bumper to bumper.
Front lift only The kit works on the front suspension and leaves the rear at its factory height, so the change is focused and the parts count stays low.
Method matched to the suspension Strut spacers suit coil-over struts, forged torsion keys suit torsion bar fronts and replacement springs suit coil front axles. ReadyLIFT uses the method each platform calls for.
Clearance for bigger tires The added front height opens the wheel wells for a larger tire. ReadyLIFT lists a tested tire size for each application.
Designed around factory geometry ReadyLIFT engineers each kit to its vehicle so the suspension works close to its original design after the lift.

Installation
Type: front leveling · Install: per-vehicle, see each kit's install sheet · Afterward: alignment, headlamp aim, ADAS check
This kit installs using the steps in ReadyLIFT's instructions for this vehicle. 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 3 hours for this kit, give or take 0.5 hours, not counting the alignment or mounting wheels and tires.
ReadyLIFT's installation instructions for this part number are linked under Resources. Read them fully before starting.

About ReadyLIFT
ReadyLIFT Suspension started in 2006 with one goal: give vehicle 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 vehicles 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.
A level stance, front to back
A leveling kit lifts the nose so the vehicle stops looking like it is leaning forward. The added front height also opens space for a larger tire without a full lift kit.
Everyday truck, better stance
The vehicle keeps doing daily work while it looks more purposeful in the driveway and fits a bigger set of tires.
Frequently Asked Questions
Straight answers on specs, fit and support
Does a leveling kit lift the rear too?
No. It raises the front only so the vehicle sits level. For height at both ends, look at ReadyLIFT's SST lift kits or add a rear block or spacer kit.
What is the largest tire it clears?
The tire size ReadyLIFT lists for this exact vehicle is in the specifications on this page. Tire dimensions vary by brand, so test fit your wheel and tire combination before mounting.
Will I need an alignment after installing it?
Yes, plan on one. ReadyLIFT notes the vehicle may need an alignment after installation, and headlamp aim should be checked at the same visit.
Does it affect driver-assistance cameras and radar?
Changing ride height can shift camera, radar and sonar aim. ReadyLIFT says to check and recalibrate these systems after installation, and some vehicles need dealer tools to do it.
Can I install it myself?
ReadyLIFT recommends a certified mechanic and says to read the instructions fully before starting. The install sheet and ReadyLIFT's estimated install time for this exact kit are on this page.
Will the vehicle still tow and haul?
Leveling removes the factory rake, so the rear can sit lower than the front under a heavy load. ReadyLIFT's rear block and spacer kits add back rear height if you tow often.
