Rancho RS7MT 4″ Front Lift Shocks for 1999-2007 GMC Sierra 1500 4WD

Part Number: RS77268

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on vehicles equipped with a 4-inch lift. Utilizing a sophisticated monotube design, these shocks provide the precision and response necessary for both technical off-road maneuvers and stable highway cruising. By separating the gas and oil with a high-pressure nitrogen charge, the RS7MT eliminates aeration and shock fade, ensuring consistent damping performance in demanding environments.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a lightning-fast response rate to ensure maximum tire-to-road contact.
• Internal Floating Piston: The dedicated dividing piston isolates the oil from the gas to provide fade-free performance during repetitive cycling.
• Hardened Nitro-Chablis Piston Rod: A 14mm heavy-duty rod provides exceptional structural rigidity to ensure long-term durability under side-load stress.
• Sealing System: An integrated wiper seal and multi-lip oil seal provide a redundant barrier against contaminants to ensure a leak-free service life.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and length-tuned to be used on vehicles already equipped with a 4-inch suspension lift kit.

What is the benefit of a monotube over a twin-tube shock?
A monotube shock like the RS7MT reacts faster to small bumps and dissipates heat much more efficiently, which prevents the “fading” feeling during long drives or off-road use.

Do these include the mounting hardware?
Yes, these shocks come with the required bushings and mounting hardware for a direct installation into the factory mounting locations.
