Fits the same truck
A mild lift, done right
An SST kit gives the vehicle more height at both ends and room for a larger tire package, while the parts stay matched to its factory suspension. It is the step between a simple leveling kit and a full big lift.
Parts matched to the platform
ReadyLIFT builds each SST kit around one suspension design, so spacers, brackets and arms locate where that vehicle needs them. The fit is specific rather than universal.
Ready for daily duty
A lifted stance with bigger tires still has to commute, tow and haul. SST kits keep a small rear rake so the vehicle sits right with weight in the bed or on the hitch.
Frequently Asked Questions
Straight answers on specs, fit and support
How is an SST kit different from a leveling kit?
A leveling kit raises only the front to cancel the factory rake. An SST kit lifts the front and the rear, so the whole vehicle gains height.
What is the largest tire it clears?
The tire size ReadyLIFT lists for this exact vehicle is in the specifications on this page. Tire dimensions vary by brand, so test fit your wheel and tire combination before mounting.
Will I need an alignment after installing it?
Yes, plan on one. ReadyLIFT notes the vehicle may need an alignment after installation, and headlamp aim should be checked at the same visit.
Does it affect driver-assistance cameras and radar?
Changing ride height can shift camera, radar and sonar aim. ReadyLIFT says to check and recalibrate these systems after installation, and some vehicles need dealer tools to do it.
Can I install it myself?
ReadyLIFT recommends a certified mechanic and says to read the instructions fully before starting. The install sheet and ReadyLIFT's estimated install time for this exact kit are on this page.
Is an SST kit covered for off-road use?
ReadyLIFT's warranty excludes damage from off-road abuse on its lift kits. Its Jeep SST and Terrain Flex kits are the exception and remain covered in recreational off-road use.

Not as simple or quick to
This is a good kit, but a few issues emerged during install that I did not see mentioned in a lot of the online content or instructions. First of all, the u bolts for the AT4 kit were roughly 6” taller than necessary. This is likely due to being used in multiple kits. But this was problematic due to the second issue: the nut and bolt fitment was extremely tight. So tight I had to use a large wrench to rotate the nut the entire length of the bolt, which created so much friction you could not touch the bolts. Maybe so have impact sockets deep enough to make this easy, but my deep socket set didn’t even get 1/3 of the way up the threads The reason these two issues were problematic is the longer bolts require cutting, and to cut you ideally get the nut higher than the cut first so you can use the remove the nut after the cut and ensure you have good threads for starting. This was virtually i
