This quality Upper Control Arm system for the Chevy Silverado 1500 & GMC Sierra 1500 provides a 3" increased ride height over stock without creating suspension bind at full droop. Lift is accomplished with spacers that utilizes the factory coilover shocks for a stock ride. The Fabtech Upper Control Arms address the geometry of the front suspension with the new ride height for proper align-ability. Heavy duty ball joints allow for extended travel to eliminate binding.Due to the GM suspension geometry there are no differential drop brackets required for the CV axles to operate properly. This 3" system features the legendary stainless steel Dirt Logic 2.5 Coilover shocks. These Coilovers are built of the highest quality materials and will surpass all shocks in corrosion resistance due to the stainless steel body and NitroSteel piston rod. They will provide an outstanding ride quality both on and offroad. Rear lift comes from 1.5" blocks and u-bolts with Dirt Logic 2.25 shocks for a balanced ride. Dirt Logic shocks are the only stainless steel body shock on the market that provide maximum corrosion resistance in harshest conditions.
