Rancho RS7MT 5-6″ Lift Shocks for 1999-2004 Chevy Silverado 2500 4WD

Part Number: RS77055 / RS77056

Summary: The Rancho RS7MT Monotube series is engineered to provide high-performance damping for lifted heavy-duty trucks and SUVs. Designed with a high-pressure nitrogen charge, these shocks eliminate oil aeration to maintain consistent control during aggressive off-road use or heavy towing. This complete set of four shocks is specifically valved to improve handling and reduce body roll for vehicles equipped with 5 to 6 inches of suspension lift.

Features

• Monotube Design: A 1.97-inch (50mm) diameter body provides increased fluid capacity to ensure cooler operating temperatures during high-demand cycles.
• Internal Floating Piston (IFP): The nitrogen gas-charged dividing piston separates the oil and gas to provide rapid response times and zero aeration.
• Hardened Nitro-Churyl Rod: A 14mm piston rod thickness provides superior structural rigidity to ensure long-term durability in harsh environments.
• Hydraulic Rebound Stop: An integrated internal bumper provides a controlled deceleration at full extension to ensure protection of the suspension components.

These are designed as a direct bolt-on replacement for vehicles within the specified lift range, utilizing OE-style mounting points for a straightforward installation.

Do these shocks come with boots?
Yes, the RS7MT series includes protective boots to shield the piston rod from road debris, salt, and mud.
