Rancho RS7MT 1.5″ Rear Lift Shocks for 1973-1990 Chevy G20

Part Number: RS77118

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on vehicles with a 1.5-inch rear lift. Utilizing a sophisticated monotube design, these shocks provide a precise, consistent response that eliminates performance fade during aggressive driving or heavy-duty use. This specific configuration is optimized for the Chevy G20, ensuring a stable ride height and improved control over factory-style twin-tube alternatives.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a faster damping response to ensure consistent control on various road surfaces.
• Floating Piston Technology: An internal dividing piston separates the gas and oil to provide zero aeration and prevent shock fade during high-frequency cycles.
• Hardened Nitro-Churyl Piston Rod: A heavy-duty 14mm rod provides maximum durability and corrosion resistance to ensure a long service life in harsh environments.
• Application-Specific Valving: Custom-tuned damping specs provide optimized stability for the Chevy G20 chassis to ensure improved cornering and towing performance.

Frequently Asked Questions

Do these shocks provide additional lift to my Chevy G20?
No, these shocks are specifically configured for vehicles that already have a 1.5-inch rear lift installed; they do not create the lift themselves.

What is the benefit of a monotube shock over a twin-tube?
Monotube shocks like the RS7MT use a single-cylinder design that dissipates heat more efficiently and uses a high-pressure gas charge to prevent fluid foaming (aeration).

Is any modification required for installation?
These shocks are designed as a direct-fit replacement for the rear position of 1973-1990 Chevy G20 models with the specified lift height.
