4" SST Lift Kit - GM Silverado / Sierra 1500 4WD 2007-2013 (part number 69-3485).

Includes TCT free floating pivot bushings that are self lubricating and eliminates friction. ReadyLIFT offers an SST Lift Kit system for the 2007-2013 1500-series Silverado/Sierra 6-lug 4WD Trucks. This system significantly increases ground clearance while allowing for tire sizes up to 33" on aftermarket wheels. The most common tire size for this application is 33x11.50. 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 2007-2013 Silverado/Sierra 1500 4WD trucks 4.0" in front thanks to tough trail-proven 4.0" powder coated 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 is 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 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 coated plate steel skid plate that utilizes the factory attachment locations for ease of installation while providing tough differential protection on rough terrain. To lift the rear of the Silverado/Sierra pickups this lift system includes 3.0" OEM-style cast iron rear lift blocks and u-bolts. Our 3.0" rear lift blocks include the correct pinion angle correction and axle locating ears for perfect fit and performance.

This block replaces the factory 1.25" rear block for an increase of 1.75" which will provide approximately 0.5" of rear to front rake. A slight rake is helpful for towing or hauling. Completing this great new lift system is 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 69-3485 SST Lift Kit System is protected by our Limited Lifetime Warranty. Upper control arms with heavy-duty ball joints. Max Lift - 4.0"F/1.75"R - Max Tire: 33". Solid Mount and even load distribution Press in 10.9 grade Hardware OEM Style Cast Blocks Will not deform or change shape No Cutting of OEM Parts or Welding Maintains Factory Ride

• The ReadyLIFT 4" SST Lift Kit is designed for use with Aftermarket Wheels with a backspacing of 5.25".
• If you intend to run the stock wheels with an aftermarket larger tire, a wheel spacer is required to prevent the 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.
• To run the OE/Factory wheels AND tires, you will need to use the ReadyLIFT 1/2 Billet Wheel Spacers for use with OE/Factory wheels and tires".
• Does NOT work with 2013 Z71 4WD trucks with Rancho front struts. For all 2007-2011 Z71's it is imperative that installer measure vehicle prior to purchase. There must be a 2.25" to 2.5" difference between the front and the rear.

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.
