The genuine XCMG Shock Absorber with OEM number 800165306 is a heavy‑duty hydraulic damper engineered for XCMG articulated dump trucks, wheel loaders, and mining vehicles. Designed to control suspension oscillation and reduce chassis impact loads, this shock absorber ensures superior ride comfort, stability, and tire contact even on severely rough haul roads. Manufactured with a hardened chrome piston rod, multi‑stage valving, and high‑temperature resistant oil, it delivers consistent damping force under extreme loads, improving operator safety and reducing component fatigue in mining and quarry operations.

The XCMG Shock Absorber 800165306 is built with a heavy‑duty twin‑tube design that separates the working chamber from the reserve tube, allowing consistent damping even during continuous high‑frequency operation. The piston features a digressive valve stack that provides soft damping at low speeds (for comfort) and progressively firmer damping at high shaft speeds (for control over large impacts). This characteristic is critical for articulated dump trucks hauling loads over corrugated haul roads.
The piston rod is induction hardened to 55‑60 HRC and hard chrome plated to resist pitting from stone chips and corrosion. The rod guide is made from sintered bronze, providing low friction and excellent wear resistance. Each shock absorber is dyno‑tested at the factory to verify force‑velocity curves, ensuring batch‑to‑batch consistency. The unit is also leak‑tested at 15 bar for 30 seconds.
OEM 800165306 is the factory‑specified shock absorber for the front and rear axle suspension of AD45, AD60, and AD80 articulated dump trucks. The eyelet dimensions (25 mm ID) and bush widths match the chassis mounts perfectly. The included rubber boots and steel washer sets are pre‑assembled, reducing installation time. The extended length of 680 mm provides full wheel travel without bottoming out, while the stroke of 235 mm covers the full articulation range of the walking beam suspension.
When replacing worn or leaking shocks, using genuine 800165306 restores original ride height control and reduces pitch and roll during cornering. Aftermarket shocks often have incorrect damping rates, leading to harshness or inadequate control, which accelerates tire wear and chassis cracking. Protect your operator comfort and structural integrity with XCMG original shock absorbers.
A 24‑month study on 40 XCMG AD60 trucks in a Western Australian iron ore mine compared genuine Shock Absorber 800165306 against aftermarket units. The genuine shocks showed no damping loss or oil leakage after 11,000 hours, while aftermarket shocks failed at an average of 2,500 hours due to seal extrusion and rod scoring. The mine reported a 76% reduction in cab vibration levels and a 22% decrease in tire wear. Annual savings in shock replacements and tire costs exceeded $94,000.
In a Peruvian copper mine operating at 4,500 meters altitude, the genuine shocks maintained consistent damping performance despite temperature variations from freezing night to hot day. The synthetic oil formulation prevented aeration and cavitation, which had plagued aftermarket shocks. The mine also noted improved suspension articulation, reducing driveline stress and eliminating five differential failures attributed to uncontrolled axle hop.
The shock absorber uses a multi‑lip rod seal made of polyurethane (95 Shore A) with a double scraper edge, preventing mud and dust ingress while retaining high‑pressure oil. The seal is backed by a bronze‑coated piston rod bearing that eliminates metal‑to‑metal contact. The internal floating piston separates oil from gas (nitrogen at 5 bar), preventing cavitation and providing consistent damping even after repeated large impacts.
The hydraulic oil is a full‑synthetic, high‑viscosity index fluid with anti‑foam additives. It remains stable from -40°C to +110°C, with a viscosity change of less than 40% across the range. The oil also contains extreme pressure (EP) additives to protect the valve stack and piston ring. No maintenance or refilling is required during normal service life; the unit is sealed for life.
Replacing a shock absorber with OEM 800165306 takes approximately 30 minutes per wheel. Support the axle, remove the lower and upper mounting bolts (M20 grade 10.9). Compress the old shock absorber if needed. Install the new shock with new bushings (supplied). Torque the mounting bolts to 180 Nm for the lower eye and 150 Nm for the upper. Do not use impact tools on the piston rod nut as it may rotate the shaft and damage the seal.
After installation, bounce the suspension to settle the shock. Inspect for oil leaks or unusual noises. Re‑torque bolts after 50 operating hours. Check the rubber boots for cracking every 500 hours; replace if torn. If the shock shows visible oil misting or the damping force feels weak (excessive bouncing), replace as a pair (both sides of the same axle). Never attempt to disassemble or refill a gas‑charged shock absorber – it is pressurized and could cause injury.
All XCMG genuine shock absorbers, including 800165306, are manufactured in IATF 16949 and ISO 9001:2015 certified facilities. Each unit is 100% force‑velocity tested on a computerized dynamometer, and a unique serial number is laser‑etched on the reservoir tube. The product is covered by a 24‑month warranty against manufacturing defects (excluding physical damage or off‑road abuse).
Using genuine XCMG shock absorbers ensures compliance with original suspension geometry and damping characteristics, protecting the vehicle’s handling and safety. Counterfeit shocks often use low‑grade oil, poor seals, and incorrect valve stacks, leading to premature failure and dangerous loss of control. Protect your equipment and operators – always insist on authentic OEM 800165306 from authorized XCMG distributors.
