Pro Comp Lift Shield, 5 Year / 60,000 Mile Powertrain Warranty

Pro Comp Suspension Systems are highly engineered and must pass rigorous quality, performance and endurance testing. The final product is what separates Pro Comp from other brands and we stand behind it. The Lift Shield Warranty goes beyond the product warranty and covers the vehicles powertrain components for 5 years/60,000 miles. Lift Shield protects you against the high cost of powertrain repairs in the event the vehicle manufacturer denies warranty coverage. Best of all, it is included FREE with your purchase of this kit!

2014 F150 Fitment: this kit will not have proper, bolt-on fitment to a 2014 F150 due to changes Ford made to the 2014's front suspension. Call 1-877-578-2433 for more information.

Wheel fitment and kit notes: This kit requires cutting your truck's subframe for proper fitment and will not fit factory 18" or 17" wheels. This kit REQUIRES at least an 18x9" wheel with a maximum of 4" to 5" of backspace. All 18x9" wheels should be test-fit prior to installation, due to design variations that can cause fitment issues. For all other fitment questions, please contact Stage 3 directly at 1-877-578-2433.
