With conventional steering stabilizers, turning in one direction creates an increase in pressure inside the stabilizer as the shaft occupies more volume in the body and displaces the oil. The repercussion is a push or pull steering force felt by the driver as the stabilizer attempts to return to its neutral state.
Key Features
- Adjustable Through Shaft Design: Enables easy rebuild service without full disassembly and provides balanced damping on compression and rebound for consistent steering response.
- Aluminum Body Construction: Dissipates heat faster than steel to prevent fade during extended use, ensuring reliable performance in demanding conditions.
- Collapsed length 10.55 inches, extended 18.65 inches for exact OEM geometry.
- External Reservoir with Compression Adjuster: 20-click adjustment increases oil capacity for better cooling and fine-tunes damping firmness to suit driving style or terrain.
- Black Anodized CNC Aluminum Components: Corrosion-resistant finish and precision machining deliver long-lasting durability and a factory-matched appearance.
- Direct bolt-on replacement for stock steering stabilizer with no modifications required.
