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.

Worked perfect for my 2015 and 2021 Toyota Runner

We've installed 2 of these on our 2015 and 2021 Toyota 4 runners. If you upgrade from ugly factory no grip stock tires to larger such as 285/70R/17. You'll need this kit to keep the tires from rubbing on the vehicle. You should also install 1.25" wheel spacers. The final result is a very nice looking lifted 4 runner. Did not appear to change the driving performance of the vehicle either. You'll maybe want some side step rails as the vehicle as the kit will make your vehicle bit higher off the ground, which is a good thing. In most cases this kit is good for a 4 runner max tires size of 285 on 17" rims. Anything bigger and you'd have to do an expensive shock type lift. The two attached photos show before and after kit installation. Now we can drive our vehicles off pavement ;)
