Like many of BDS's other IFS suspension systems for the GM trucks, this 4.5" system is packed with the same features and benefits of the current 6.5" kit but designed for a lower lift height for those looking for a more modest setup. Like the 6.5" system, the 4.5" includes one piece crossmembers, differential drop brackets, ductile cast iron steering knuckles and bolt-on no torsion bar drop brackets that keep the torsion bars in the factory location at the frame. Also included are stainless steel front brake lines, extended sway bar links and differential skid plates. The front replacement steel splash guard with the BDS logo finishes out the front of the clean, high clearance design. Rounding out the front of this kit are FOX 2.0 performance series IFP shocks or BDS NX2 shocks.
In the rear, the system comes with a 2" block and u-bolt setup that levels the vehicle perfectly. For those looking for a little more height in the rear, 3 and 4 inch block options are available to help you fine tune the amount of rake you want in the rear of the truck. All kits come finished in a durable textured black powdercoat and sent with all hardware packs to complete the install along with step-by-step installation instructions. All BDS kits include Factory Protection Plus for the ultimate extended warranty to include BDS's No Fine Print Warranty and a 5year-100k mile drivetrain warranty to match the dealer. Improve the look and capability of your Chevy/GMC 2500/3500HD truck with this new 4.5" lift system from BDS Suspension.
