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.
