ReadyLIFT 4 in. SST Lift Kit

New – now includes ultra strong TCT free floating pivot bushings that are self lubricating and eliminates friction.

ReadyLIFT is proud to offer an SST Lift Kit system for the 2007-2018 1500-series Silverado/Sierra 6-lug 2WD Trucks. Increased requests from customers wanting a true 4.0″ Lift Kit for their Silverado trucks encouraged ReadyLIFT research and development to engineer the only 4.0″ completely bolt-on lift kit on the market today. The 69-3285 4.0″ SST Lift Kit, just like the 69-3485 4WD version, is the result of over six months 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 33×11.50. 22×9.5 with 5.5″ backspacing requires no fender modifications. 17×9 +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 2007-2016 Silverado/Sierra 1500 2WD 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.

At the heart of the system is our all-new 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 new polyurethane bushings. Our new trail-tested Control Arms will provide additional clearance and correct geometry to allow for increased suspension travel. 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 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!

Like all ReadyLIFT products, the 69-3285 SST Lift Kit System is protected by our Limited Lifetime Warranty.

NOTE: 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

NOTE: Some 2016 models are coming with a New Hydro Form (Stamped) UCA and LCA that is not allowing for installation of the 4” SST kits. These models can be identified with a build code of “AVV”. This lift kit is not recommended for these models with stamped steel Control Arms at this time. This kit fits 2007-2013 2WD AND 2014-16 2WD 1500 trucks that have the steel upper control arm ONLY. Not for use on 2014-up trucks with Aluminum upper Control Arms.

NOTE: Not for use for off-roading purposes.
