A leveling kit primarily raises the front of a truck or SUV to reduce the factory rake. A suspension lift raises the vehicle farther and may raise both the front and rear, depending on the system. ReadyLIFT SST kits sit between a basic level and a full big lift.

Start with your goal. If you mainly want a level stance, stay mild. If you want more tire clearance and a visibly lifted truck without going extreme, an SST system is often the middle ground. If maximum height and tire size are the priority, look at a complete big-lift system.

Tire fitment is vehicle-specific. Lift height is only part of the equation—wheel width, offset/backspacing, tire width, trim level and available clearance all matter. Use the tire recommendation listed on the exact product page and review the ReadyLIFT Tire/Wheel Sizing Guide before purchasing wheels and tires.

Yes. Two trucks with the same tire diameter can have very different clearance depending on wheel width and offset. Too much positive or negative offset can create contact with suspension components, fenders or liners. Follow the vehicle-specific wheel and tire guidance for the kit you are installing.

Any suspension modification can change how the vehicle feels. The amount of change depends on the kit design, lift height, springs, shocks, tires and application. If ride control is a major priority, consider a ReadyLIFT Performance Series system with premium Falcon damping.

Not on every vehicle. Some applications benefit from or require upgraded upper control arms to maintain proper geometry, alignment range or component clearance at the intended lift height. If a ReadyLIFT system includes UCAs, they are there as part of the application-specific suspension solution—do not substitute or omit components without verifying fitment.

Yes. A professional wheel alignment should be part of the installation process after suspension ride height is changed. Follow the instructions supplied with your exact ReadyLIFT kit and verify steering, suspension, brake-line and tire clearance before regular use.

It can increase clearance at the body, frame and suspension areas depending on the design. However, the lowest point of a solid axle or differential does not automatically move farther from the ground just because the suspension is lifted. Larger tires are what increase axle/differential ground clearance.

A properly selected suspension system can be used on trucks that tow and haul, but installing a lift does not increase the vehicle manufacturer’s GVWR, payload or tow rating. Stay within the OEM ratings and choose a suspension/shock package appropriate for how the truck is used.

An aftermarket suspension modification does not automatically cancel the entire vehicle warranty. A warranty claim can be affected if the modification is determined to have caused the failure in question. ReadyLIFT also offers ReadyGuard supplemental powertrain coverage on qualifying products and vehicles, subject to program terms and registration requirements.

That depends on the kit and your experience. Some leveling systems are relatively straightforward; larger suspension systems can require more involved disassembly, torque procedures and alignment work. If you are not fully comfortable with suspension installation, use a qualified professional installer and follow the supplied ReadyLIFT instructions exactly.

Larger and heavier wheel-and-tire combinations can affect acceleration, fuel economy and braking feel. A significant change in tire diameter can also affect speedometer and odometer accuracy unless the vehicle is recalibrated where supported. Factor the complete wheel-and-tire package into the build—not just lift height.
