Summary: The Rancho RS5000X series features a patented progressive rebound and compression disc system that significantly improves ride quality on your Isuzu Ascender. Designed for vehicles at stock height, these twin-tube gas-pressurized shocks provide a perfect balance of durability and on-road comfort. By reducing harsh impacts and body roll, these shocks ensure a stable and controlled driving experience whether you are commuting or hauling light loads.

Features

• Cross-Tuned Technology: A unique valve system provides precise control at both high and low speeds to ensure a smooth, comfortable ride across varying road surfaces.
• Twin-Tube Design: The 2.25-inch diameter shock body provides increased fluid capacity to ensure cooler operating temperatures during extended use.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior corrosion resistance and durability to ensure long-term seal integrity.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in aeration and foaming to ensure consistent damping performance under load.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks are configured for a 0-inch lift and are designed to replace factory-length shocks without changing the ride height.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable; if the outer tube is dented by road debris, the inner working tube remains unaffected, allowing the shock to continue functioning.

Does this include both rear shocks?
Yes, this SKU (2xRS55387) includes a pair of rear shocks for a complete rear axle installation.
