4.5 Inch Lift Kit

The Rough Country 4.5" M1 Suspension Lift Kit is engineered for Chevy Silverado and GMC Sierra 1500 2WD owners seeking aggressive lift without compromising ride quality. This kit combines front coil springs and rear lift blocks to achieve commanding ground clearance and a leveled appearance, eliminating factory rake for a balanced, trail-ready look. It is designed to accommodate up to 33-inch tires. The kit includes 3" Lift Knuckles to relocate the front spindle while preserving factory geometry, 2" Front Coil Springs for smooth suspension travel and comfort, and a 3" Rear Lift Block with U-Bolts to raise the rear axle and level the stance. Nitrogen-charged M1 Monotube Shocks are included for both front and rear, featuring velocity-sensitive damping for a balance of stock-like highway comfort and responsive off-road performance. Important fitment notes specify that this kit fits only 6-lug wheel models. It does NOT fit 2004–2006 models equipped with torsion bar front suspension. Minor trimming of the fender shroud may be necessary when installing tires larger than 33 inches, up to 35 inches. The installation process is 100% bolt-on, requiring no cutting or drilling to the vehicle's frame or suspension hardpoints.
