Rancho RS5000X 2-3″ Front Lift Shocks for 1941-1963 Jeep MB, M38 4WD

Part Number: RS55119

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to significantly improve off-road handling and on-road comfort for your vintage Jeep. Engineered with a unique progressive engagement valving system, these shocks provide a smooth ride during normal cruising while instantly firming up to handle impacts on rough terrain. This gas-pressurized solution is specifically configured for vehicles with 2-3 inches of front lift, ensuring the piston remains in the optimal operating zone to prevent bottoming out.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a soft initial response to ensure maximum comfort during daily driving.
• Gas Pressurization: High-pressure nitrogen charging reduces aeration and shock fade to ensure consistent damping performance under heavy cycling.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased oil capacity and dent resistance to ensure long-term durability in harsh environments.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior scuff resistance and corrosion protection to ensure seal longevity.

Frequently Asked Questions

Will these shocks lift my Jeep?
No, these shocks do not create lift. They are specifically lengthened and valved to be used on vehicles that have already been equipped with 2-3 inches of suspension lift.

Are boots included with the RS5000X series?
Yes, these shocks come standard with red protective boots to shield the piston rod from dirt, mud, and debris.

What is the benefit of the Twin-Tube design for off-roading?
The twin-tube design is highly durable; if the outer body is dented by a rock, the inner cylinder (where the piston moves) remains unaffected, allowing the shock to continue functioning.
