ReadyLIFT is proud to introduce a new SST Lift Kit system for the 2007-2013 1500-series Silverado/Sierra 6-lug 4WD Trucks.
(NOTE: Does Not Work With AWD Denali Trucks - Will NOT work with 2013-UP Z71 4WD trucks with Rancho front struts - Does NOT work on 2014 model 1500 trucks). For all 07-11 Z71’s it is imperative that they measure vehicle prior to purchase. There must be a 2.25” to 2.5” difference between the front and the rear. If you have a Z71 truck you will want "69-3488" kit.
The 69-3486 4.0" SST Lift Kit features heavy duty fabricated box steel control arms with virtually indestructable PFT-lined Uniball Pivot Bearings that are vastly superior to traditional ball joints. The addition of these super strong arms allows you to use your truck off road like you want without ever having to worry about ball joint fatigue. Each arm includes an exclusive custom machined aluminum seal cap to keep dirt and debris out. This is ideal for those in snow or sandy areas. But that's not all! This kit also includes newly designed UCA inner bushings and new washer backing spacer sleeves which greatly prolong the life of the bushings. If you plan to off road your truck or drive in aggressive road situations, this is the kit you want! 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.

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" 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.
The second important product that makes this kit possible is our 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, our CNC-machined brackets cannot ever bend, break or cause any driveline problems when using 4WD mode. That is guaranteed! Accompanying our differential drop brackets is a thick powdercoated 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 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 .5" of rear to front rake. A slight rake is helpful for towing or hauling.
Completing this great new lift system are a set of steel rear shock extensions. No need to replace your great-riding 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! And that's important!
Like all ReadyLIFT products, the 69-3486 SST Lift Kit System is protected by our Limited Lifetime Warranty.
Not for use on AWD Denali Trucks.

At ReadyLIFT we design our lift systems for proper fit, and that includes tire and wheel fitment information. Our goal is always to provide the maximum tire size that will fit without any clearance issues. We do not recommend that you install a larger wheel/tire than what we recommend. However should you decide you want to run a larger tire such as a 305 or similarly larger, the fender lip (front fenderwell) will have to be modified. This image below illustrates how some customers have modified their fender lip and liner to provide necessary clearance for 305 tires.
