Rancho RS7MT 1.5″ Rear Lift Shocks for 1963-1972 GMC C2500 2WD Rear Leaf Spring

Part Number: RS77118

Summary: The Rancho RS7MT monotube shock absorber is engineered for high-performance handling and rapid heat dissipation on vehicles with 1.5 inches of rear lift. Utilizing a high-pressure nitrogen gas charge and a floating dividing piston, these shocks eliminate oil aeration and foaming during aggressive driving. This specific configuration is designed to provide precise control and consistent damping for the GMC C2500, ensuring a stable ride regardless of the terrain or load.

Features

• Monotube Construction: A 2-inch diameter body with a high-pressure gas charge provides rapid heat dissipation to ensure consistent performance during heavy-duty use.
• Internal Dividing Piston: The full-floating piston separates nitrogen gas from the shock oil to provide zero aeration and immediate response to surface changes.
• Hardened Nitro-Carburized Rod: The heavy-duty piston rod provides superior scuff and corrosion resistance to ensure long-term seal integrity.
• Polyurethane Bushings: High-density mounting material provides enhanced durability and road feedback to ensure a more connected driving experience.

Frequently Asked Questions

Are these shocks sold as a pair?
Yes, this SKU (2xRS77118) includes a complete pair of shocks for the rear axle.

Will these shocks lift my GMC C2500?
No, these shocks do not create lift. They are specifically valved and length-matched for vehicles that have already been modified with a 1.5-inch rear lift.

What is the benefit of the RS7MT monotube over a standard shock?
The monotube design dissipates heat much faster and uses a high-pressure charge to prevent the oil from foaming, which means your suspension won’t get “soft” or fade during long trips or rough roads.
