The FABTECH Upper Control Arm system raises ride height by 1.5" while maintaining full droop travel to avoid suspension bind. Lift is achieved with spacers that use the factory coil-over shocks to preserve a stock-like ride. The system corrects front suspension geometry for proper alignment at the new ride height. Heavy-duty upper ball joints provide extended travel to eliminate binding. Rear lift is provided by 1.5" blocks and new U-bolts.
Made in the USA.
