Rancho RS5000X Series Rear Shock Absorber for 2007-2018 Jeep Wrangler & Wrangler JK RS55330

Fits 2007-2018 Jeep Wrangler and Wrangler JK (Rubicon, Sahara, Sport, X, and Unlimited models).

The Rancho RS5000X Series Rear Shock Absorber (RS55330) is engineered to deliver a smooth on-road ride while maintaining the high-speed control required for off-road environments. Utilizing an exclusive Progressive Engagement Valving (PEV) system, this shock minimizes initial impacts at low speeds and reduces ride harshness across varying terrains. The nitrogen gas-pressurized twin-tube design is specifically tuned for the Jeep Wrangler's suspension geometry to prevent fluid foaming and damping fade during extended use.

• Progressive Valving: Custom-tuned PEV system reduces harshness and improves handling on and off-road.
• Heavy-Duty Construction: Features a 16mm nitro-carburized piston rod for scuff resistance and a 35mm sintered iron piston for enhanced structural integrity.
• All-Weather Performance: Large twin-tube body filled with fluid rated for internal operating temperatures from -40°F to 248°F.
• Gas Pressurized: Charged to 150 PSI to minimize aeration and maintain consistent damping performance without disc flutter.
• Protective Components: Includes a polyvinyl protective boot and polyurethane rebound bumpers to absorb impacts and protect internal seals.
• Technical Specs: 16mm rod diameter, 35mm piston, nitrogen gas charged, part number RS55330.

This rear shock installs directly to factory mounting points, providing a durable upgrade for stock or leveled Jeep Wrangler JK platforms. Backed by Rancho’s Limited Lifetime Warranty.
