Rancho RS7MT 1.5″ Rear Lift Shocks for 1967-1986 GMC C1500 2WD Rear Leaf Spring

Part Number: RS77118

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation, making it the ideal solution for 1967-1986 GMC C1500 owners looking to stabilize their rear suspension. Utilizing a sophisticated monotube design, these shocks provide the precision damping required to eliminate body roll and maintain tire contact on uneven surfaces. Configured specifically for 1.5-inch rear lift heights, they offer a significant upgrade in response over traditional twin-tube shocks for both daily driving and light hauling.

Features

• Monotube Design: A high-pressure nitrogen gas charge provides a lightning-fast damping response to ensure consistent control during rapid suspension cycling.
• Internal Floating Piston: The physical separation of gas and oil provides aeration-free performance to ensure zero fade during high-temperature operation.
• Hardened Nitro-Coated Rod: The heavy-duty piston rod construction provides superior scuff resistance to ensure long-term seal integrity in harsh environments.
• Application-Specific Valving: Custom-tuned shim stacks provide optimized resistance for the GMC C1500 chassis to ensure a balanced, firm ride quality.

Frequently Asked Questions

Will these shocks lift my GMC C1500?
No, these shocks do not create lift. They are specifically valved and sized to function with a vehicle that has already been equipped with 1.5 inches of rear lift.

What is the benefit of the RS7MT monotube over a standard shock?
The monotube design dissipates heat more effectively and uses a high-pressure charge to prevent the oil from foaming, which maintains consistent damping performance during heavy use.

Are these sold as a pair?
Yes, this specific SKU (2xRS77118_n602) includes two rear shocks for a complete axle installation.
