The DZ95259591312 Right Suspension Mount serves as the primary physical link between the suspension system and the truck’s frame. Its core function is to securely anchor the suspension components, such as the spring or airbag assembly, to the chassis on the right side of the vehicle. This connection must be incredibly robust to handle dynamic loads that can exceed the truck’s static weight during cornering, braking, and traversing uneven terrain.
By providing a solid mounting point, the DZ95259591312 ensures that suspension forces are transferred efficiently to the frame, preventing excessive movement that could lead to misalignment or component failure. A secure mount is fundamental for maintaining the designed suspension travel and ensuring that the truck’s ride height and stability are consistent under all load conditions.
This mount is not a universal part; it is specifically engineered for SHACMAN truck models utilizing Cummins engines and a straight (non-drop) frame design. This specific application is crucial because engine weight, vibration characteristics, and frame rail dimensions vary between configurations. The DZ95259591312 is designed with precise bolt patterns, mounting hole locations, and a shape that clears the Cummins engine components and fits perfectly against the straight frame rail. Using the correct mount ensures there is no interference with engine accessories, exhaust systems, or other chassis components. This application-specific design of the DZ95259591312 guarantees optimal performance and longevity, as it accounts for the unique stresses and spatial requirements of this popular powertrain and chassis combination.
Beyond providing a rigid connection, the DZ95259591312 plays a vital role in isolating the chassis and cab from excessive vibration and shock. The mount is typically constructed with a combination of a strong metal bracket and a resilient rubber or polyurethane bushing. This bushing acts as a damper, absorbing high-frequency vibrations from the road and the engine before they can travel into the frame and, ultimately, the cab.
This dampening effect is critical for reducing driver fatigue, minimizing noise levels inside the cabin, and protecting sensitive electronic and electrical components from vibration-induced damage. A high-quality mount like the DZ95259591312 maintains this isolation throughout its service life, preventing the hardening or cracking of the bushing material that would transmit harsh impacts directly to the chassis.
The longevity of the DZ95259591312 is a direct result of its material composition and manufacturing process. The metal bracket is fabricated from high-tensile steel, often with reinforced gussets at stress points, and is treated with anti-corrosion coatings to resist rust from road salt and moisture. The bushing is made from a specially formulated rubber compound that retains its elasticity across a wide temperature range, from freezing winters to scorching summers.
This compound is resistant to oil, grease, and ozone, which can cause premature degradation. The entire assembly of the DZ95259591312 is engineered to resist metal fatigue and material breakdown, ensuring it can endure millions of stress cycles over the truck’s operational life without failing.

Proper installation of the DZ95259591312 is critical for its performance and safety. The process involves safely supporting the truck’s weight, removing the old, worn mount, and thoroughly cleaning the frame mounting surface. The new DZ95259591312 is then positioned, and the supplied or specified high-grade bolts are inserted. Crucially, these bolts must be tightened to the manufacturer’s specified torque values using a calibrated torque wrench. Overtightening can crush or distort the bushing, reducing its damping ability and leading to premature failure. Undertightening can cause the mount to loosen, leading to dangerous movement and accelerated wear. Following the correct installation procedure ensures the DZ95259591312 functions as designed and provides a secure, long-lasting connection.
Several clear signs indicate the DZ95259591312 mount may be worn and require replacement. A noticeable increase in cabin vibration, especially at idle or on rough roads, is a primary symptom. Audible clunking or banging noises from the right front or rear suspension area when going over bumps or during acceleration/braking can indicate excessive movement in a failed mount.
Visible inspection may reveal cracks in the rubber bushing, separation of the rubber from the metal, or severe corrosion on the bracket. Uneven tire wear or a slight change in vehicle ride height on one side can also be indirect signs of mount failure. Addressing these symptoms promptly by installing a new DZ95259591312 prevents further damage to suspension components and maintains vehicle safety.
A secure and intact DZ95259591312 Right Suspension Mount is fundamental for predictable vehicle handling. It maintains the precise location of the suspension components relative to the frame. A worn or collapsed mount can allow the suspension to shift slightly, altering the wheel alignment settings (camber and caster). This misalignment leads to uneven tire wear, causing the truck to pull to one side, and increases steering effort. It also reduces the effectiveness of the suspension, leading to a less stable and more floaty feel on the highway, especially during lane changes or in crosswinds. Replacing a faulty mount with the genuine DZ95259591312 restores proper suspension geometry, ensuring sharp handling, even tire wear, and confident driving dynamics.
