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

Part Number: RS55113

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to provide exceptional durability and ride quality for your classic Jeep. Engineered with a unique progressive engagement valving system, these shocks effectively manage impact energy during off-road excursions while maintaining smooth street manners. This configuration is specifically valved to accommodate vehicles with 2 to 3 inches of rear lift, ensuring the suspension remains controlled under various load conditions.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between damping forces to ensure consistent comfort on uneven terrain.
• Gas Pressurized Twin-Tube: High-pressure nitrogen gas charge provides a reduction in aeration and foaming to ensure fade-free performance during sustained cycling.
• Glass-Filled Fluoro-Ethylene Band: A specialized piston seal provides a friction-reducing interface to ensure long-term durability and smooth rod stroke.
• Double-Welded Mounts: Reinforced loop-style end treatments provide increased structural integrity to ensure reliability in demanding environments.

Frequently Asked Questions

Will these shocks lift my Jeep?
No, these shocks do not create lift. They are specifically sized and valved to function correctly on vehicles already equipped with a 2-3 inch lift kit.

Are the dust boots included?
Yes, this pair includes Rancho’s signature red protective dust boots to shield the shock rods from debris and corrosion.

Is the twin-tube design better for my classic Jeep?
The twin-tube design is ideal for these applications as it provides excellent dent resistance; if the outer tube is dinged by a rock, the inner working cylinder remains functional.
