Rancho RS5000X 2-3″ Rear Lift Shocks for 1953-1975 Jeep M38A1 4WD

Part Number: RS55113

Summary: The Rancho RS5000X Series gas-pressurized shocks are engineered to provide a significant upgrade in ride quality and durability for your Jeep M38A1 or FJ-9. Utilizing a sophisticated progressive engagement valving system, these shocks minimize harshness during initial impacts while maintaining firm control over rough terrain. This twin-tube design is specifically configured for vehicles with 2-3 inches of rear lift, ensuring the suspension maintains optimal travel and stability for both work and recreation.

Features

• Progressive Engagement Valving: A custom-tuned compression disk stack provides reduced harshness during initial movement to ensure a smoother ride on uneven surfaces.
• Gas Pressurized Twin-Tube Design: The 150 PSI nitrogen gas charge minimizes aeration and foaming to ensure consistent damping performance under heavy cycling.
• Heavy-Duty Body: A 2.25-inch diameter reserve tube provides increased oil capacity to ensure lower operating temperatures and reduced fade during extended use.
• Nitro-Carburized Piston Rod: The 16mm hardened rod construction provides superior scuff resistance and corrosion protection to ensure long-term seal integrity.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically sized and valved to accommodate vehicles that have already been modified with 2-3 inches of rear lift height.

What is the benefit of the nitrogen gas charge?
The 150 PSI nitrogen charge exerts pressure on the hydraulic fluid, which prevents the oil from foaming (aeration). This ensures that the valving remains precise even during rapid suspension movement.

Are the dust boots included?
Yes, this pair of shocks includes Rancho’s signature red protective boots to shield the piston rods from dirt, debris, and road salt.
