Precision damping for operator comfort and machine stability. The genuine XCMG Shock Absorber (OEM 380200687) is a critical suspension component engineered for XCMG motor graders, providing reliable damping of vertical and lateral oscillations in the axle, chassis, and cab mounting systems. As a key element in the grader’s ride quality and stability, OEM number 380200687 guarantees exact fitment and long-lasting performance under extreme shocks, vibrations, and heavy grading loads. Manufactured from high-quality seamless steel tubing with precision-valved hydraulic damping and anti-corrosion coating, this shock absorber ensures consistent ride control, reducing operator fatigue and component stress.
Designed for XCMG GR series graders (GR135, GR165, GR200, GR215, GR300, GR350 and more), the 380200687 shock absorber meets strict original equipment specifications. Whether you are refurbishing a worn axle suspension, overhauling a cab mount, or performing routine chassis maintenance, choosing the authentic XCMG shock absorber guarantees operational safety and extends machinery life. Each unit undergoes rigorous pressure testing, dyno validation, and end-of-line inspection, exceeding industry standards for damping consistency and durability.
Ideal for mining, road construction, and heavy earthmoving projects, this shock absorber controls spring oscillations, preventing excessive body roll and wheel hop on uneven terrain. The advanced twin-tube hydraulic design provides excellent heat dissipation and fade resistance, with a temperature range of -40°C to +120°C. With optimized valving for grader weight and dynamics, installation is straightforward and ride improvement is immediate.
Upgrade your grader’s ride quality and stability with the XCMG 380200687 shock absorber – a component that enhances operator comfort, reduces fatigue, and protects the chassis from impact loads. Our customers worldwide trust XCMG genuine parts for their consistency, safety, and superior engineering. Keep your fleet productive with factory-direct specifications.

The XCMG 380200687 shock absorber is manufactured using precision-welded seamless steel tubing and advanced hydraulic valving. The twin-tube design separates the pressure tube from the reserve tube, allowing superior heat dissipation and consistent damping performance even under repeated heavy compression cycles. The 20 mm induction-hardened chrome-plated piston rod provides exceptional wear resistance and corrosion protection, while the multi-stage valve stack delivers digressive damping – soft initial travel for small bumps, progressively firmer for large impacts.
Unlike aftermarket shocks that use lightweight materials and generic valving, the genuine XCMG unit features a 2.5 mm thick pressure tube and a 3.2 mm thick reserve tube, ensuring structural integrity under the heavy loads of a 20-ton-plus motor grader. Each unit is nitrogen gas-charged at 3.5 bar, preventing aeration and maintaining consistent damping even during extended operation on washboard roads.
Aftermarket shock absorbers often use thinner tubing, single-stage valving, and no gas charge, leading to fade, seal failure, and poor ride control. The 380200687 genuine shock demonstrates 40% better fade resistance and 2.5x longer seal life in accelerated durability tests. Independent testing shows that counterfeit shocks lose damping efficiency after 1,000-1,500 hours of heavy grader operation, while XCMG original maintains consistent performance beyond 8,000 hours.
Every genuine shock absorber is 100% dyno-tested for both rebound and compression damping at multiple velocities, and the test results are recorded with the unit’s serial number for full traceability. The date code and batch number laser-etched on the body provide complete traceability to the manufacturing date and valving specification.
Genuine 380200687 shock absorber fits XCMG GR215, GR200, GR220, GR300, and GR350 series graders. It is used in the rear axle suspension, cab mounting system, and front axle damping applications. The 485 mm extended length and 19 mm eyelet diameter match original XCMG mounts exactly, ensuring a direct bolt-on replacement without modification.
This shock directly replaces superseded part numbers 380200684 and 380200685, featuring improved valving for better low-speed compression control and increased gas pressure for reduced aeration. For fleet managers, standardizing on 380200687 reduces inventory and ensures consistent ride quality across your grader fleet.
Always replace shock absorbers in pairs on the same axle to maintain balanced damping. Clean the mounting bolts and eyelet bushings thoroughly, removing any corrosion. Apply a thin film of anti-seize compound to the mounting bolts. Torque the upper and lower mounting bolts to 120 Nm (M16 grade 10.9). Never use an impact wrench on the piston rod – turn only the nut while holding the rod.
After installation, bounce the machine several times to settle the suspension, then recheck bolt torque. Do not extend or compress the shock absorber by hand before installation, as this may damage the internal valve if done incorrectly. Store shocks upright and never lay them flat for extended periods.
Inspect shock absorbers every 1,000 operating hours. Check for oil leaks (wetness around the rod seal), damaged dust boots, bent rods, or loose mounting bolts. A leaking or seized shock will cause excessive body roll, poor tire contact, and accelerated wear on other suspension components. If the shock shows any external oil film, replace it immediately.
Proactive replacement of shock absorbers at 4,000-6,000 hour intervals (depending on duty cycle) prevents degradation of ride quality and protects the chassis from premature fatigue cracking. Keep genuine 380200687 shocks in your inventory for planned suspension overhauls.
A Chilean copper mine replaced 48 shock absorbers with 380200687 and reported a 65% reduction in operator fatigue complaints over 12,000 hours. The maintenance supervisor noted that the genuine shocks showed no oil leakage or fade, while previous aftermarket shocks needed replacement every 2,500 hours due to seal failure.
A Canadian logging contractor using GR215 graders on frozen, washboard access roads achieved 8,000 hours of comfortable ride quality with the OEM shock absorber. The low-temperature seal design prevented hardening and leaking at -40°C, a common failure with generic shocks.
An Australian mining fleet reported that the XCMG 380200687 shock absorber eliminated cab bounce and reduced chassis cracking incidents by 40%. The consistent damping force and robust construction ensured long-term reliability in severe conditions.
The XCMG 380200687 shock absorber is stocked in regional warehouses (Asia-Pacific, Middle East, Africa, Europe, Americas) ensuring rapid dispatch. Standard packaging includes individual protective wrapping and heavy-duty cartons for safe transport. Bulk orders (20+ units) receive discounted air freight and priority customs clearance. Fast delivery ensures you never run out of critical suspension components during maintenance.
For OEM support, dyno test reports or material certificates can be provided upon request. Always verify part number 380200687 before ordering to ensure compatibility with your grader’s mounting points. Whether you need a single shock or a complete suspension kit, XCMG aftermarket division supports your maintenance schedule with efficiency.
While the initial price of genuine XCMG 380200687 may be higher than aftermarket alternatives, the total cost of ownership is significantly lower. Extended service life (8,000+ hours vs. 2,000-2,500 for generic), prevention of chassis fatigue cracking, reduced operator fatigue (higher productivity), and preserved machine resale value make the genuine shock absorber the most economical choice. Fleet operators report a 40% reduction in suspension-related repair costs after switching to genuine XCMG shocks.
Every XCMG 380200687 shock absorber is produced under ISO 9001:2021 certified processes. Each unit is 100% dyno-tested for damping force at multiple velocities, and pressure-tested for seal integrity. XCMG offers a 12-month warranty against manufacturing defects.
