Ohlins POS5N21 Road & Track Front Coilover Strut Kit Porsche 911 Carrera 4 Turbo 996

The Öhlins POS5N21 is a Road & Track front coilover strut assembly engineered specifically for the Porsche 911 (996) Carrera 4, Carrera 4S, Turbo, and Turbo S. Drawing on Öhlins' decades of motorsport heritage, this front strut delivers a precise balance between track-day performance and everyday road comfort.

At the heart of the POS5N21 is Öhlins' patented Dual Flow Valve (DFV) technology, which simultaneously controls low- and high-speed compression and rebound damping with a single adjustment. A simple clockwise turn of the signature gold knob transitions the damper from street to race mode, giving drivers full control over chassis behavior without tools or complicated setup procedures.

Key Features:

• DFV (Dual Flow Valve) Technology — Patented Öhlins system that adjusts all four damping characteristics simultaneously
• Single-knob adjustment — Quickly switch between street and track damping modes
• Individual ride height adjustment — Fine-tune front stance to suit driving conditions
• Rebuildable construction — Serviceable design for long-term value and performance maintenance
• Corrosion-resistant finish — Salt spray tested to ISO 9227 standards for lasting durability
• Reuses OEM upper mounts — Retains stock front upper mounts for straightforward installation
• 2-Year limited warranty — Backed by Öhlins' worldwide warranty program

The POS5N21 front strut is a direct component of the Öhlins Road & Track coilover system for the Porsche 911 (996) platform, designed to deliver measurably improved bump absorption, traction, and cornering precision. Compatible with Carrera 4, Carrera 4S, Turbo, and Turbo S variants of the 996-generation 911.
