LAS Profender twin‑tube Nitro Gas shock absorbers are built for hard work and long miles. With a large 40 mm bore and a stout 20 mm shaft, they deliver confident control under load while smoothing out corrugations, ruts, and potholes. A low‑pressure nitrogen charge keeps the oil from aerating as temperatures climb, so damping stays consistent from the first kilometer to the last.

Why It Matters

• Big‑bore design improves heat capacity and fade resistance on rough roads.

• 20 mm hard‑chrome shaft adds strength for heavy‑duty and towing use.

• Nitrogen gas pocket prevents cavitation for reliable damping in sustained corrugations.

• Tuned valving targets a comfortable, composed ride without losing body control.

Construction & Materials

• Twin‑tube layout protects the working piston from stone strikes and offers generous oil volume.

• Precision piston with Teflon (PTFE) band reduces friction for smooth, long‑lasting performance.

• High‑quality steel components sourced from Sandvik, Sweden, for strength and durability.

• Tight manufacturing tolerances ensure accurate, repeatable damping force.

Performance Highlights

• Stable, predictable handling with improved bump absorption and rebound control.

• Consistent performance over long drives and changing temperatures.

• Suitable for daily driving, touring, towing, and commercial duty.

Installation & Setup

• Direct replacement for factory shocks when matched to the correct application.

• Pair with appropriate springs and ride height for best results.

• After installation, recheck all fasteners and perform a wheel alignment if other suspension components were changed.

Good to Know

• Shock tuning, spring rate, and tyre choice collectively influence ride and handling.

• Inspect shocks periodically for leaks, bush wear, and stone damage—especially after off‑road use.

• Allow a short bedding‑in period for seals and bushings to settle.
