What is the purpose of the nitro-carburized piston rod?

The 16mm nitro-carburized piston rod is designed to resist scuffs and corrosion. This helps ensure the longevity and smooth operation of the shock absorber over time.

How does the all-weather fluid help?

The all-weather fluid allows the shock absorber to operate cooler, even under extreme temperatures ranging from -40 to 248°F. This helps maintain consistent performance and vehicle control.

Does this shock absorber come with a protective boot?

Yes, this Rancho RS55393 shock absorber includes a polyvinyl protective boot. This boot helps shield the piston rod from dirt and debris, contributing to its durability.

Product Details

The 16mm nitro-carburized piston rod on this Rancho RS55393 shock absorber is built to resist scuffs and corrosion, which is a solid detail for your 2000-2004 Nissan Xterra. This rear shock is designed to improve your vehicle's handling both on the pavement and when you venture off-road.

Rancho uses a large twin-tube body filled with all-weather fluid that can handle temperatures from -40 to 248°F, helping to keep the shock cooler during operation. Inside, a 35mm sintered iron piston and a Progressive Engagement Valving system work together to absorb impacts smoothly and maintain control over the shock's motion, reducing harshness at low speeds. The nitrogen gas charge, pressurized to 150 PSI, helps prevent the oil and gas from mixing, which reduces damping performance fade and foaming during heavy use.

You'll also find double-welded loops at stress areas for added strength and a polyvinyl protective boot to shield the rod. The fluon-banded piston enhances responsiveness to changing road conditions, contributing to an overall smoother ride.
