Genuine Hendrickson Genuine S-23566 Shock Absorber – INTRAAX / VANTRAAX Suspension

Shock Strap Kit S-23086-1

The Hendrickson S-23566 Shock Absorber is a premium, heavy-duty suspension component engineered specifically for Hendrickson’s world-class trailer systems. This genuine OEM shock is designed to provide maximum stability, reduce vibration, and protect your trailer’s cargo and air springs from excessive wear.

Unlike "universal" shocks, the S-23566 features specific bore diameters and stroke lengths tailored to the geometry of INTRAAX® and VANTRAAX® systems. Built with rugged inner metal bushings and a specialized seal design, this shock is designed to withstand high-torque mounting requirements and harsh road conditions, ensuring a longer damping life and lower overall maintenance costs.

Key Performance Features:

- Precision Engineering: Specifically tuned for Hendrickson air suspensions to optimize ride quality and load distribution.

- Superior Durability: Features solid inner metal bushings and a heavy-duty dust shield to protect internal components from road debris, moisture, and grime.

- Hydraulic Lock-Out: Includes a built-in recoil cutoff to prevent over-extension of the suspension.

- OEM Reliability: Designed to handle the high torque levels required for secure mounting on heavy-duty trailer axles.
