Cab Rear Suspension Shock Absorber (Coil Spring Hydraulic Damper Assembly) DZ13241440150
1. The spring is responsible for bearing the weight of the cab, and the hydraulic damping cylinder absorbs the bumps and shocks from the road surface;
2. It suppresses the up-and-down bouncing, backward tilting, and nodding of the cab, and controls the shaking of the cab during braking/acceleration;
3. It attenuates the vibrations from the chassis and isolates the vibrations from being transmitted to the interior of the cab;
4. It protects the rear suspension bracket, bushing, and connecting bolts of the cab, preventing the fatigue cracking of the sheet metal;
5. It reduces the abnormal noise caused by bumps, significantly improving the comfort of long-distance driving and reducing driver fatigue.
1. Integrated structure of spring and hydraulic damping: The spring bears the load and the hydraulic cylinder provides damping and shock absorption, balancing both support force and shock absorption effect;
2. OEM original installation hole spacing, direct bolt replacement, no need to modify the bracket;
3. Both ends are vulcanized rubber sleeves, with built-in buffering and noise reduction, reducing hard metal impacts;
4. Cylinder body is phosphated black paint, resistant to sand and rust, suitable for harsh conditions in construction sites and national highways;
5. Heavy-duty reinforced spring, resistant to fatigue, not prone to deformation; bidirectional hydraulic damping, stable compression and rebound damping;
6. Factory-determined damping pressure detection, standard replacement parts for heavy truck cab suspension.
Solved fault problems:
1. The rear of the cab bounces excessively, causing a "clanging" impact sound when passing through potholes;
2. During braking and starting, the cab shows obvious nodding, tilting and shaking;
3. The original shock absorber leaks oil, the damping fails, the spring is weak and the rebound is uncontrollable;
4. The rear suspension bracket and bushings are frequently worn, and the screws are prone to breakage;
5. During high-speed driving, the cab shakes severely, the jolting sensation is strong, and the driver is prone to fatigue.
Which truck models does it fit?
Fits SHACMAN Delong F2000, F3000, M3000, X3000 cab rear mounting. It is the rear cab shock with integrated spring.
What is the function of this shock absorber?
It supports the cab weight by coil spring and absorbs road vibration & impact by hydraulic damper. It controls cab bouncing, pitching and shaking during braking or acceleration. Protect cab rear bracket and rubber bushings and improve driver riding comfort.
What material is this shock made of?
Alloy spring steel for coil spring, seamless steel cylinder, hard chrome plated piston rod, high quality hydraulic oil, oil-resistant seal, vulcanized rubber bushing on both ends.
What symptoms show the old shock needs replacement?
Oil leakage on shock body, weak damping, deformed/broken spring, obvious cab bouncing, knocking noise over bumps, cracked rubber bushes.
