SST Lift Kits by ReadyLIFT: A gray lifted Jeep Gladiator with a ReadyLIFT decal on a dirt trail with pine trees at sunset.

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.

4” Ready Lift!!

For my budget this was the best option for me. I love the lift, and the ride is really good. Definitely better than past lifts that I have had that make you. It is stiff but not so stiff that it hurts when you hit a bump. I have not had any problems with a death wobble. I took it off road a few times now. It rides just as good off road. No complaints here.

Ready lift 4" lift

Extremely pleased with this kit thus far !! Only been installed for 3 days but it's night & day compared to stock , rides really nice and those Falcon shocks are plush! Install was straight forward but expect more than 4"s !!! And expect to replace at a minimum the rear brake lines cause they are stretched & I had to leave calipers removed until last minute because I was afraid that when the wheels were added the weight would break them !!!!
