The ReadyLIFT 69-3485 4.0" SST Lift Kit for the 2007-2013 1500-series Silverado/Sierra 6-lug 4WD Trucks is the result of extensive product development followed by rigorous on and off road testing.
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. With a 295/70r17 minor trimming/modification required.
Note: This kit is designed to be used with aftermarket wheels.
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, these 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 ReadyLIFT's 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 their Patent Pending CNC-machined 6061-T6 billet Aluminum differential drop brackets. When raising the front suspension 4.0", the differential must be lowered to maintain front axle and CV angles. ReadyLIFT has engineered a differential drop system that cuts installation time in half compared to other similar kits. Unlike other differential drop brackets made from steel plate that bend and can cause CV failure, ReadyLIFT's CNC-machined brackets cannot ever bend, break or cause any driveline problems when using 4WD mode. That is guaranteed!
Accompanying their 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. The 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 lift system is a set of steel rear shock extensions. No need to replace your OEM rear shocks with aftermarket shocks on this kit. These new shock extension brackets keep the rear shocks in the factory mounting position which means your truck will maintain factory ride quality!
Like all ReadyLIFT products, the 69-3485 SST Lift Kit System is protected by their Limited Lifetime Warranty.
NOTE: The ReadyLIFT 4" SST Lift Kit is designed for use with Aftermarket Wheels with a backspacing of 5.25".
NOTE: 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".
NOTE: Does Not Work With AWD Denali Trucks
NOTE: Does NOT work with 2013 Z71 4WD trucks with Rancho front struts.
NOTE: 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.
NOTE: Not designed for off-road use.
