Rancho RS5000X 4.5″ Rear Lift Shocks for Hummer H2

Part Number: RS55297

Summary: The Rancho RS5000X series leverages advanced CrossTune technology to provide a significant upgrade for your Hummer H2’s rear suspension. Designed specifically for vehicles equipped with a 4.5-inch lift, these twin-tube gas-pressurized shocks utilize a unique valving system that balances on-road comfort with off-road durability. The increased fluid capacity and robust construction ensure consistent damping performance, effectively managing the heavy unsprung weight of larger tire and wheel combinations common on lifted H2 models.

Features

• CrossTune Technology: A proprietary progressive valving system provides a smooth ride during initial travel while increasing firmness during high-velocity impacts to ensure superior control on rough terrain.
• Nitrogen Gas Pressurization: A high-pressure gas charge minimizes aeration and foaming provides consistent damping force to ensure fade-free performance during spirited driving.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides increased structural rigidity and resists scuffing to ensure long-term seal integrity.
• Polyurethane Bushings: High-density mounting material provides improved vibration dampening and durability compared to standard rubber to ensure a quiet and stable ride.

Frequently Asked Questions

Will these shocks provide my Hummer H2 with 4.5 inches of lift?
No, these shocks do not create lift. They are specifically valved and sized to accommodate the travel requirements of a vehicle already equipped with a 4.5-inch lift kit.

What is the benefit of the twin-tube design for an H2?
The twin-tube design is exceptionally durable; the outer tube acts as a shield, meaning if the body is dented by a rock or debris, the inner cylinder and piston remain functional, ensuring you aren’t stranded on the trail.

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