Introducing the GMC K25 Suburban Suspension Lift Kit for the '77-'78 models by Rough Country. Elevate your ride with this robust 6-Inch Lift Kit complete with 56-Inch Rear Springs, designed to provide a balanced, powerful stance while maintaining exceptional performance on and off the road.

The Rough Country 6" GM Suspension Lift System is expertly engineered to offer your truck an impressive transformation from front to back. This easy-to-install lift kit ensures that the front of your vehicle aligns beautifully with the rear, creating a level and commanding presence. Not only does it enhance the ride height, but it also offers a more aggressive look without compromising ride comfort or performance.

This lift kit includes quality components such as front lifted leaf springs and rear leaf springs that maintain the efficiency of your vehicle's geometry for a factory-like experience, even after lifting. The addition of brake line brackets ensures all elements remain at optimum angles. The real piece de resistance is the inclusion of Rough Country's premium N3 shocks. These finely tuned 10-stage variable high-pressure Nitrogen charged shocks provide an optimal mix of off-road prowess and highway comfort, featuring a durable 18mm spring-loaded piston rod and a large 54mm shock body for faster cooling.

Features

• 6-Inch Lift Kit for an enhanced ride height and aggressive look
• Front and rear leaf springs for perfect alignment and stability
• Premium N3 series shock absorbers for balanced on and off-road performance
• Increased ground clearance
• Capability to fit up to 37" tires with proper wheel backspacing

Please note that this kit is compatible only with models featuring front and rear solid axles and 56-inch factory rear leaf springs. If your vehicle has a front sway-bar, we recommend using drop brackets for optimal results, and those with factory quad shocks can simply switch to a single aftermarket shock.
