Rancho RS7MT 2.5-4″ Rear Lift Shocks for 1969-1986 GMC K2500 4WD

Part Number: RS77112

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on vehicles used for both daily driving and off-road excursions. Featuring a sophisticated monotube design, these shocks provide the precision response needed to maintain stability over uneven terrain. Specifically configured for 2.5 to 4 inches of rear lift, they ensure your suspension geometry remains optimized while eliminating the fade common in traditional twin-tube shocks.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a quicker damping response to ensure consistent control on washboard roads.
• Internal Floating Piston: The physical separation of gas and oil provides aeration-free performance to ensure fade-free damping during aggressive maneuvers.
• Hardened Nitro-Carburized Rod: The ultra-smooth rod finish provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
• OE-Style Mounts: Heavy-duty vulcanized rubber bushings provide vibration isolation to ensure a quiet and comfortable ride.

Why Choose This Product?

• Engineering Advantage: Unlike standard shocks, the RS7MT utilizes a high-pressure monotube architecture that reacts instantly to surface changes, preventing the “mushy” feel of aeration.
• Performance Benefit: Drivers will experience significantly reduced body roll and improved tire-to-ground contact, resulting in a more predictable and confident driving experience.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened to accommodate GMC K2500 models that have already been equipped with a 2.5″ to 4″ rear lift kit.

What is the benefit of a Monotube shock over a Twin-Tube?
Monotube shocks like the RS7MT dissipate heat more efficiently and use a dividing piston to prevent oil foaming, which ensures consistent performance even during heavy off-road use.

Are boots included with these shocks?
Yes, these shocks come with protective boots to shield the nitro-carburized piston rod from rocks, mud, and debris.
