Product Introduction

Structure

This rear air spring shock absorber integrates a reinforced rubber air bellows with a hydraulic damper, featuring a heavy-duty steel top mounting eye, multi-layered air spring, and bottom mounting hardware with rubber bushings.

Performance

It combines variable air-spring load support with stable hydraulic damping, resisting high internal pressures and operating reliably from -40°C to 120°C for leak-free, long-lasting heavy-duty performance.

Core Function

1. Restricts the resonant movement of the rear air spring suspension, preventing excessive vertical oscillation of the rear axle to maintain tire adhesion on rough and uneven road surfaces.

2. Mitigates the impact force transmitted from the rear wheels to the frame when driving over potholes, speed bumps or uneven terrain, protecting the rear axle, suspension links and frame from structural fatigue.

3. Stabilizes the vehicle’s rear end during high-speed driving, cornering and load shifting by reducing rear sway, ensuring consistent handling and responsive braking performance.

4. Serves as a key load-bearing and damping connection between the rear axle and frame, complementing the air spring system to maintain the designed ride height of the vehicle’s rear under varying load conditions.

Frequently Asked Questions — Air Spring Rear Shock Absorber 81.41722.6051

What symptoms indicate this air spring rear shock absorber needs replacement?

When the 81.41722.6051 air spring begins to fail, you will typically notice increased cab vibration at the rear, a sagging or uneven cab ride height, or audible clunking noises from the rear cabin mounts when driving over uneven surfaces. If the rubber bladder shows visible cracks or air leaks, replacement is necessary immediately to prevent further damage to surrounding cab components.

Is this air spring shock absorber an exact OEM fit for SHACMAN trucks?

Yes. The part number 81.41722.6051 corresponds directly to the SHACMAN original equipment specification. Bolt patterns, air fitting connections, and overall dimensions match the factory design, so installation requires no modification or adapters.

How long does this air spring rear shock absorber typically last?

Under normal operating conditions — regular highway and mixed-terrain use — this component is engineered to deliver reliable performance for at least 200,000 kilometers. However, extreme conditions such as persistent overloading, severe off-road use, or chemical exposure may reduce service life. Regular visual inspection during scheduled maintenance helps catch early wear.

Can I use this part on both the left and right sides of the cab rear suspension?

The 81.41722.6051 air spring rear shock absorber is designed for the rear cab suspension mounting point. Depending on your specific SHACMAN model configuration, confirm whether left and right positions share the same part number or require mirrored variants. Our team can verify compatibility based on your truck model and VIN.

What pressure should the air spring operate at after installation?

Operating air pressure should follow the SHACMAN workshop manual specification for your particular model, which typically falls within a controlled range managed by the cab leveling system. Over-inflating or under-inflating the air spring can lead to premature wear or poor ride quality. Always refer to the OEM service manual for exact pressure settings.
