Part Number: RS55114 / RS55116

Summary: The Rancho RS5000X series utilizes an innovative Cross-Tuning system to provide a significant upgrade in ride quality for classic 4WD applications. Designed as a high-durability twin-tube solution, these shocks feature a massive 2.25-inch body and gas-pressurization to maintain consistent damping on and off the road. This complete set is specifically configured for vehicles with 2.5 to 4 inches of suspension lift, ensuring the piston remains within its optimal operating range for maximum control.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother transition between damping forces to ensure a comfortable street ride without sacrificing off-road stability.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and shock fade to ensure consistent performance during extended cycles.
• Twin-Tube Body: A 2.25-inch outer reserve tube provides increased oil capacity and physical dent resistance to ensure long-term reliability in harsh environments.
• Nitro-Carburized Piston Rod: A heavy-duty hardened rod construction provides superior scuff and corrosion resistance to ensure seal integrity.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with a 2.5-inch to 4-inch suspension lift to ensure proper travel.

Why is the bushing fitment tight on the Dodge W100?
The inner diameter of the bushing is intentionally snug for a secure fit; we recommend using a silicone-based lubricant and a press or vice for easier installation over the mounting pins.

Are boots included with these shocks?
Yes, this set includes Rancho’s signature red protective boots to shield the piston rods from debris and contaminants.
