Transform Your Truck's Capability: The GMC K15 Suburban Suspension Lift Kit by Rough Country is the perfect solution for enhancing the ruggedness and functionality of your vintage '77-'78 GM truck. This 2-inch lift kit not only refines the vehicle's appearance with an aggressive stance but also substantially boosts its off-road performance capabilities.

Engineered for superior ride quality, this lift kit includes front lifted leaf springs specifically designed for your application. They ensure increased ground clearance and maintain a comfortable, controlled ride without compromising quality. The inclusion of rear lift blocks and brake line brackets ensures that the factory geometry is preserved, promising a smooth ride post-installation. For a more complete suspension overhaul, consider opting for the available replacement rear lifted leaf springs, which provide consistent lift and eliminate the need for rear blocks altogether. The Rough Country kit is further enhanced by the N3 Series Shocks—valved for perfect compatibility with your vehicle. These premium shocks offer an optimal mix of on-road comfort and off-road control, thanks to features like a 10-stage variable valving system and a robust 54mm shock body with an 18mm piston rod.

Features

• Application-Specific Front Leaf Springs: Ensures perfect fit and ride quality.
• Clears 33-Inch Tires: Sufficient clearance for a 33" tire with the correct backspacing.
