Rancho RS7MT 2.5-4″ Rear Lift Shocks for 1981-1991 Chevy Blazer 4WD

Part Number: RS77112

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on lifted applications. Utilizing a sophisticated monotube design with a physical dividing piston, these shocks provide the precise response needed to eliminate aeration during aggressive off-road use. Configured for 2.5 to 4 inches of rear lift, they ensure your classic Blazer maintains stability and control across varied terrain.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a quicker damping response to ensure consistent control on rough washboard surfaces.
• Internal Dividing Piston: The physical floating piston separates gas from oil to provide fade-free performance and prevent aeration during high-frequency cycling.
• Hardened Nitro-Coated Rod: A 14mm heavy-duty piston rod provides superior scuff resistance to ensure long-term seal integrity in harsh environments.
• Application-Specific Valving: Custom-tuned shim stacks provide the ideal balance of street comfort and off-road firmness to ensure a predictable driving experience.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically long-travel units configured for vehicles already equipped with a 2.5-inch to 4-inch rear lift kit.

What is the benefit of the RS7MT monotube over a standard shock?
The monotube design features a larger piston for better damping and a separate gas chamber that prevents the oil from foaming, ensuring the shock doesn’t lose its “firmness” over rough terrain.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS77112_n24) includes two rear shocks for a complete axle installation.
