Shacman X5000 Spacing Block Assembly is an OEM vibration isolation kit for chassis and cab mounting. It includes a rubber damping block bracket, absorber block, and hexagon head bolts.
Manufactured by Shacman, this assembly reduces transmitted vibration from the frame. The Shacman X5000 Spacing Block Assembly ensures smoother ride quality and protects sensitive components.
The Rubber Damping Block Bracket (Part DZ96259520474) is a precision‑stamped steel holder. It securely positions the rubber absorber block between chassis rails and the cab subframe. Made from 5mm thick HSLA steel with zinc‑nickel plating (500h salt spray). The bracket features two locating dimples and four bolt holes. It prevents lateral movement of the damping block while allowing vertical compression. Designed to withstand 25 kN static load without deformation. This component is essential for maintaining correct cab height and alignment. Direct replacement for worn or rusted brackets. It also acts as a protective cage for the rubber absorber. Install using the provided hexagon head bolts.

The Rubber Absorber Block (Part 81.96210.0379) is the core damping element of the Shacman X5000 Spacing Block Assembly. It is a natural rubber compound with a Shore A hardness of 65. The block measures 80mm x 80mm x 40mm and is molded with a central steel bushing. It absorbs vertical and lateral vibrations from the chassis. The rubber is ozone and oil resistant, with an operating range of -40°C to +100°C. The block compresses 5mm under rated load, providing progressive damping.

The Hexagon Head Bolt (Part Q150B0825TF3) is a grade 10.9 M8x25mm fastener. It is used to secure the rubber damping block bracket to the chassis rail. Supplied in pairs, these bolts feature a zinc‑flaky coating (Geomet 321) for corrosion resistance. The thread has a pre‑applied micro‑encapsulated locking patch (red). Torque to 35 Nm. The bolt head is 13mm across flats, with a captive washer design. It is tested to 1,500 Nm tightening torque without thread stripping. Each bolt can be reused up to 3 times if thread locker is reapplied. For the Shacman X5000 Spacing Block Assembly, use these bolts to attach the bracket through the rubber absorber block. Always replace bolts if they show rust or thread damage.

Remove old spacing block. Clean mounting surfaces. Insert rubber absorber block into bracket. Position assembly between chassis and cab subframe. Insert hexagon head bolts through bracket and rubber bushing. Tighten to 35 Nm, then angle torque +90°. Use new bolts each time. Re-torque after 500 km. Ensure rubber block is not twisted.
Apply anti-seize on bolt threads if reusing (though new bolts recommended). Inspect rubber for cracks annually. Replace if hardness change or visible damage.
Rubber absorber: Natural rubber (NR) / polybutadiene (BR) blend, carbon black filled. Vulcanized at 160°C, post‑cured 2 hours. Tensile strength 18 MPa, elongation 400%. Bracket: S420MC micro‑alloyed steel, stamped and deburred. Coating ZnNi 12μm with clear sealer. Bolts: B7 grade steel, rolled threads, locking patch nylon 11.
Every batch of rubber blocks is tested for durometer and compression set. Brackets are 100% checked for hole alignment. Torque retention test for bolts. Traceability via date code.
Worn spacing blocks cause cab rattles, cracked panels, and driver fatigue. Replacing with genuine Shacman X5000 Spacing Block Assembly reduces cab repair costs by 70% and improves driver retention. Lower maintenance compared to solid or homemade mounts.
Bulk orders (10+ kits) receive 10% discount. Download catalog or request quotation via buttons above. Quick shipping from regional distribution centers.
Excessive cab movement, clunking over bumps, visible rubber cracking or crumbling, rust on bracket, loose bolts, cab leaning to one side. Replace immediately with Shacman X5000 Spacing Block Assembly. Worn absorbers can lead to cab mount failure.
Inspect every 100,000 km. Check rubber hardness with durometer – replace if below 55 Shore A. Check bracket for cracks at weld points.
Generic rubber blocks often use reclaimed rubber with poor ozone resistance. They lack the steel bushing, causing bolt shear. Brackets are thinner (3mm) and not galvanized. Our genuine Shacman X5000 Spacing Block Assembly uses virgin rubber, full steel bushing, and 5mm bracket with ZnNi coating. Bolts have pre‑applied locker, not just standard bolts. Choose original for safety and longevity.
Final recommendation: Always replace the complete spacing block assembly as a set. The Shacman X5000 Spacing Block Assembly ensures proper cab isolation and chassis protection. Trust genuine Shacman parts for original fit and performance.
