4" SST Lift Kit - GM Full-Size SUV 2WD/4WD (with Cast Al Or Stamped Steel UCA) 2015-2020 (part number 69-3496).

Includes TCT free floating pivot bushings that are self lubricating and eliminates friction. ReadyLIFT offers a SST Lift Kit system for the 2015-2020 1500-series GM 6-lug 4WD SUV/SUTs with factory Aluminum suspension. This system significantly increases ground clearance while allowing for tire sizes up to 33" tire on an aftermarket wheel. The most common tire size for this application is 33x12.50 (max).

In order to install a 33x12.50 (305/55/20) with aftermarket wheels, some minor trimming of the inner fenderwell may be required. 22x9.5 with 5.5" backspacing requires no fender modifications. 17x9 +0 offset on a 285/70R17 will fit with no rubbing. The ReadyLIFT 4.0" SST Lift Kit will raise the 2015-2020 Chevy Suburban, Chevy Tahoe and GMC Yukon 1500 4WD SUVs 4.0" in front thanks to tough trail-proven 4.0" powdercoated steel strut extensions that bolt directly to the top of the factory strut.

Unlike some kits which require you to cut off your strut studs or break the top hat seal which are irreversible modifications, our rugged strut extensions require No Modifications to be made to the strut in order to install the extension. This guarantees the strut will maintain the factory integrity as well as drastically reducing installation time. Two key products were developed to make achieving 4" of lift without modifications a possibly.

At the heart of the system is our 100% DOM tubular upper control arm. This new heavy-duty control arm features OEM-style ball joints pre-pressed into a strong crown that retains OEM geometry throughout the suspension cycle and doesn't require any modifications to the spindle. That means no drilling or machining to make the ball joints fit the spindle. The new Control Arms include TCT polyurethane bushings.

The second important product that makes this kit possible is our Patent Pending CNC-machined 6061-T6 billet Aluminum differential drop brackets. ReadyLIFT has engineered a differential drop system that cuts installation time in half compared to other similar kits. Accompanying our patent pending differential drop brackets is a thick powder coat plate steel skid plate that utilizes the factory attachment locations for ease of installation while providing tough differential protection when off roading.

To lift the rear of the GM coil spring-equipped SUVs, this lift system includes 3.0" powder coat steel coil spring spacers. The strong coil spacers insert into and top of the factory spring which maintains the great factory ride! In addition, a slight rake is helpful for towing or hauling. New longer and stronger rear sway bar end links and bump stop extensions are also provided to keep the rear suspension working properly.

Completing this great new lift system are a set of steel rear shock extensions. No need to replace your comfortable factory rear shocks with inferior aftermarket shocks. These new shock extension brackets keep the rear shocks in the factory mounting position which means your truck will ride great! Like all ReadyLIFT products, the 69-3496 SST Lift Kit System is protected by our Limited Lifetime Warranty and ReadyGuard PowerTrain Warranty. Includes New Tubular Upper Control Arms

Fitment and Installation Notes

• For use with Factory ALUMINUM Knuckle Suspension or Stamped Steel Front Suspension.
• Not for use on cast steel suspension.
• Not for use on AWD vehicles.
• Will not work with rear airbag suspension. Will not work with Magneride applications.
• ReadyLIFT's goal is to provide a true 4.0" lift kit that is completely bolt-on; no drilling, cutting or welding required.
• With a 295/70r17 minor trimming/modification required.
• This kit is designed for use with aftermarket wheels.
• When raising the front suspension 4.0" the differential must be lowered to maintain front axle and CV angles.
• If you intend to run the stock wheels and tires, a wheel spacer is required to prevent the factory tire from touching the control arm at full locked turn.
• ReadyLIFT has developed a CNC-machined billet Aluminum wheel spacer 10-3485 for use with factory wheels which have the stud pockets cast into the wheel next to the lug holes on the back side of the wheel.
• Installation of these kits may cause rear axle shift and an adjustable rear track bar or drop bracket may be required.
• Will not work with rear airbag suspension.

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
