Ready Lift is the fastest, safest and least expensive way to lift, level, or raise the rear of today's most popular trucks and SUV's and add wheels and tires up to 37 inches in diameter. While other lift kits cost thousands to buy and hours to install, Ready Lift can be installed in as little as 1 hour, and can cost less than the price of a single custom wheel. Ready Lift recommends custom wheels no wider than 9.0 inches with 4.5 inches - 5.5 inches of backspacing on most applications. Using wheels wider than 9.0 inches may require a larger backspacing or a reduced tire height to minimize the chance of tire to fender clearance problems on some applications. Ready Lift states that it is the responsibility of the installer to verify correct and safe fitments. Ready Lift does not assume responsibility for any errors or misapplication contained within this guide.
