Zone Offroad D175N Nitro Shock Absorber Twin-Tube Nitrogen Gas Charged

The Zone Offroad D175N Nitro Series shock absorber delivers confident on- and off-road performance through a precision-engineered twin-tube design with fully displaced valving. Vehicle-specific nitrogen gas charging ensures split-second damping response and greatly reduces aeration for consistent, fade-free performance mile after mile.

Key Features:

• Twin-Tube Design — Nitrogen gas-charged internal construction for reliable, consistent damping
• 10-Stage Velocity-Sensitive Valving — Automatically adapts to changing road conditions for a smooth, controlled ride both on- and off-road
• Heavy-Chromed 5/8" Rod — Double-chromed hardened steel shaft resists corrosion, pitting, and road debris damage
• 1-3/8" Fluon-Banded Piston — Reduces internal friction for smoother, more consistent piston travel
• Full Displaced Valving — Optimizes both compression and extension travel for improved ride quality
• Self-Lubricating Seals — Extends service life with reduced maintenance requirements
• Dual Welded Ends — Reinforced construction for maximum strength and durability
• Matte Black Finish — Durable coating protects against corrosion and trail wear
• Sold Individually — Includes bushings and sleeves for straightforward installation

The Zone Offroad D175N Nitro shock is engineered for trucks and SUVs running lifted suspension systems, offering a performance upgrade over factory dampers without sacrificing everyday drivability. Backed by Zone Offroad's limited lifetime warranty covering defects in materials and workmanship.
