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

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.
• Integrated Dirt Wiper Seals: The sealing system helps keep moisture, dirt, and debris from entering the shock and contaminating the oil or internal seal.

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.
