Rancho RS7MT 1.5″ Rear Lift Shocks for 2019-2025 GMC Sierra 1500 New Body

Part Number: RS77269

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on the 2019-2025 GMC Sierra 1500. Utilizing a sophisticated monotube design, these rear shocks provide the precision required to manage the increased unsprung weight of larger tire and wheel packages. Configured for 1.5-inch rear lift heights, they eliminate the “floaty” feel often associated with stock dampers, ensuring a stable and controlled ride during off-road excursions or highway towing.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides rapid response times to road inputs to ensure consistent damping performance under aggressive use.
• Internal Floating Piston: The physical separation of gas and oil provides zero aeration to ensure fade-free performance during high-frequency cycling.
• Hardened Nitro-Coated Rod: A 14mm piston rod provides superior corrosion resistance and durability to ensure long-term seal integrity in harsh environments.
• Application-Specific Valving: Custom-tuned shim stacks provide optimized rebound and compression rates to ensure the vehicle remains composed over uneven terrain.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to accommodate vehicles already equipped with 1.5 inches of rear lift.

What is the benefit of a monotube over a twin-tube shock?
The monotube design features a single cylinder and a floating piston that prevents the mixing of oil and gas, which eliminates “shock fade” during heavy off-road use.

Are these shocks sold as a pair?
Yes, this SKU (2xRS77269) includes 2 shocks to complete the rear axle of your vehicle.
