Product Overview
McGaughys Suspension is pleased to announce their all new GMC Sierra 3500HD 4" premium lift kit. Mcgaughys packed this kit with a lot of new features. First off they include their very own M84 controlled shocks that are finely tuned specifically for this truck. Its a true 4" drop crossmember and taller knuckle so factory steering & cv axle angles are maintained. A no torsion bar drop bracket is utilized to maintain maximum ground clearance. If you get in a tight spot the 3/16" thick skid plate will protect your differential. McGaughys also designed the knuckle to allow fitment of the factory 20" wheels with a 35x12.50 tire or up to a 37x12.50 tire on a 18x9 wide wheel with a 5.75" backspacing on the single wheel trucks. Dual rear wheel trucks can fit up to a 37x12.50 tire. This kit comes ready to install, 100% bolt on, NO welding and with a professional Satin Black Powder Coat finish.
