The 801970528 Shock Absorber Assembly is a genuine XCMG cab suspension component designed for GR series motor graders. This heavy-duty shock absorber reduces cab vibration, improving operator comfort and reducing fatigue during long shifts. The 801970528 shock absorber assembly features a nitrogen-charged cylinder and a chrome-plated piston rod, providing consistent damping performance. For all your heavy equipment needs, trust genuine Howo Truck Parts as well as XCMG original components. It is a critical component for maintaining operator well-being and machine control on GR series graders.
The 801970528 Shock Absorber Assembly is manufactured to OEM specifications, with an extended length of 420 mm and a compressed length of 280 mm. The damping force is 1800 N at 0.3 m/s, providing optimal vibration isolation for the cab mounting system. The cylinder is made from seamless steel tube with a black e-coat finish, and the piston rod is hard chrome-plated for corrosion resistance. As a genuine XCMG part, it matches the original mounting eye diameters, stroke, and damping curve exactly.
Engineered for extreme durability, the 801970528 Shock Absorber Assembly has an operating temperature range of -40°C to +100°C and is filled with high-viscosity index hydraulic oil. The nitrogen gas charge prevents cavitation and ensures fade-free performance. Each assembly is 100% tested for damping force, gas pressure, and leakage. Using genuine XCMG shock absorbers prevents cab bounce, reduces wear on cab mounts, and ensures a comfortable ride quality for the operator.

Genuine XCMG shock absorber assemblies are essential for operator comfort and long-term cab structural integrity. Their precision valving and robust construction outlast generic replacements, ensuring a smooth ride for thousands of hours.
Aftermarket cab shocks often use low-quality oil and seals that leak or fade after a few months of heavy use. The genuine 801970528 Shock Absorber Assembly from XCMG is built with high-viscosity index hydraulic oil and double-lip polyurethane seals. Independent tests show that OEM shocks maintain 90% of their damping force after 5,000 hours of operation, while generic shocks may lose up to 50% of their performance. This reliability keeps the cab stable and comfortable, reducing operator back strain and fatigue.
Each 801970528 Shock Absorber Assembly is traceable to its production batch, with records of damping force curves and gas pressure checks. The shock is stamped with the XCMG part number and date code for easy identification. XCMG’s quality control includes 100% dynamometer testing for both rebound and compression forces, plus random sampling for endurance cycling (1 million cycles). Only shocks that meet all specifications are shipped, ensuring perfect performance.
Installing the 801970528 Shock Absorber Assembly requires lifting the cab or accessing the mounting points from below. Use a jack to support the cab if removing the shock from a cab suspension system. Remove the old shock by unbolting the upper and lower eyelets (12 mm bolts, torque 50 Nm). Install the new shock with the rod facing upward (as marked). Do not compress the shock before installation; it will extend naturally.
Inspect the 801970528 Shock Absorber Assembly every 1,000 hours for oil leaks, rod pitting, or worn bushings. If any oil mist is visible or the shock feels spongy, replace it immediately. When replacing one shock on a multi-shock cab system, replace all units on the same axle to maintain balanced damping. Store spare shocks horizontally in a cool, dry place. Keep a spare shock in your parts inventory, as a failed unit can cause cab bounce and premature wear of other suspension components.
A worn or leaking cab shock absorber allows excessive cab movement, causing operator discomfort and reducing control precision. The genuine 801970528 Shock Absorber Assembly restores proper damping, keeping the cab stable even on rough terrain. Operators report less back pain and higher concentration levels after replacing old shocks. The nitrogen gas charge also prevents foaming, ensuring consistent performance during long shifts.
In a fleet study of 20 XCMG GR215 graders, those fitted with genuine 801970528 Shock Absorber Assemblies had 80% fewer operator complaints about cab bounce and 50% longer life of cab mount bushings over 4,000 hours. The improved ride quality also reduced fatigue-related errors. For contractors who value operator retention and productivity, OEM cab shocks are a wise investment.
XCMG’s shock absorber plant uses automated assembly lines with precision valve tuning. The 801970528 Shock Absorber Assembly cylinder is drawn from seamless steel tube and e-coated for rust protection. The piston rod is centerless ground, polished, and hard chrome-plated to a surface finish of Ra 0.2 µm. The piston valve is laser-welded for consistency. After assembly, each shock is filled with nitrogen and tested on a computerized shock dyno. Random samples are subjected to 1 million cycles on a test rig to verify durability.
All 801970528 Shock Absorber Assemblies are individually boxed with protective plastic caps on the rod. Bulk orders of 10 or more are shipped in reinforced cartons. XCMG’s global distribution centers maintain stock of this common wear item, with same-day shipping available for urgent orders. For fleet operators, consignment stock and scheduled replacement programs are available via the contact buttons above.
The 801970528 Shock Absorber Assembly directly replaces original part numbers 801970527 and 801970529. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders with factory cab suspension. This shock is used on the front cab mounts. For the rear cab mounts, use part 801970530. Always verify your cab model year and suspension configuration before ordering.
When replacing a shock, also order new mounting bushings (part 801970531) and bolts (801970532). XCMG recommends replacing shocks every 4,000 hours or at the first sign of leakage. Keep one spare 801970528 Shock Absorber Assembly in your service truck for quick replacement. For fleet operators, bulk orders of 10 or more include a 10% discount and free shipping.
For custom valving (e.g., heavier damping for severe terrain), use the buttons above to contact our technical sales team. Always provide your grader’s serial number and a photo of the original shock when ordering the 801970528 Shock Absorber Assembly to ensure perfect fitment.
