ReadyLIFT SST Lift Kit, full kit on a studio background: two black upper control arms, strut spacers, rear blocks, U-bolts, spacers and a black skid plate on white

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.

Over all great kit

Really pleased with quality of lift kit. I would have hoped for better install instructions as the instructions that came with kit are not as descriptive as I hoped far. Better help was achieved through videos found on line.

Plug n play not so much.

Don't get me wrong, I am very pleased with the kit. Just make sure if your a weekend mechanic like myself, you can reason through minor glicthes. The bolts provided to mount front diff back after inserting spacers weren't optimal. A quik trip to fastenal solved that. There was atear on the boot on one of the ball joints when I recieved kit, but the people at Readylift shipped one right out to me. Truck looks good. I've got all the redneck girls swooning over me now.

Seems Decent

The parts in this kit seem sturdy and of good quality, but... maybe the kit needs another design lookover. It did not level my truck even a little bit (2017 Sierra Denali). Now im in the process of saving for another brand of lift. Would not recommend if you want a level look.
