ReadyLift introduces a new SST lift kit system for the 1500-series Silverado/Sierra 6-lug 4 wheel drive trucks from 2007-2010.
The SST lift kit 4.0 inch is the result of over six months of extensive product development followed by rigorous on and off road testing.
ReadyLift's goal is to create a true 4.0 inch lift kit that is completely bolt-on; no drilling, cutting or welding required.
This system significantly increases ground clearance while allowing for tire sizes up to 33 inch 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 inch 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.
This kit is designed for use with aftermarket wheels.
The ReadyLift SST lift kit 4.0 inch will raise the 2007-2010 Silverado/Sierra 1500 4WD trucks 4.0 inch in front thanks to tough trail-proven powder coated steel strut extensions that bolt directly to the top of the factory strut.
Unlike some kits which require you to cut off the strut studs or break the top hat seal which are irreversible modifications.
The rugged strut extensions require no modifications to be made to the strut in order to install the extension.
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, which means no drilling or machining to make the ball joints fit the spindle.
The new control arms include 90-degree grease fittings to ensure the life of the new polyurethane bushings.
Our new trail-tested control arms will provide additional clearance and correct geometry to allow for increased suspension travel.
