In the long-haul transportation scenario of MAN trucks, the stability of the seat shock absorption system directly affects the driving experience. Data shows that 75% of MAN trucks with more than 2 years of service have original shock absorption component failures, which manifest as "reduced shock absorption leading to seat bumps" and "adjustment cylinder jamming that cannot adapt to road conditions," increasing the driver's lumbar fatigue rate by 40% after long-haul driving. Recently, SW, a brand specializing in heavy-duty
Truck Seat Parts R&D, launched
Adjustment cylinder parts for MAN (MAN truck adjustment cylinder parts) — a three-model kit of
81623406036/81623846008/81623406035 — designed with
High performance truck seat shock absorber as the core, providing an upgrade solution for the MAN truck seat shock absorption system.
As
Adjustment cylinder parts for MAN specially designed for MAN, this
81623406036 81623846008 81623406035 truck parts comprehensively optimizes the "narrow adaptation and weak shock absorption" of the original shock absorption cylinder:
Different from single-model accessories, SW achieves "seamless coverage" of MAN models through subdivided models:
- Model Division: 81623406036 adapts to the MAN TGX series (produced after 2019), 81623846008 adapts to the MAN TGS series, and 81623406035 adapts to the MAN TGL light truck series. The cylinder mounting hole spacing and air pressure interface are completely consistent with the original, allowing direct replacement without hole expansion or pipeline modification;
- Function Compatibility: Retains the original "5-speed damping adjustment" and adds a "road condition adaptation" mode, which can automatically adjust the shock absorption strength according to road bumps (such as gravel roads, national highways). The adjustment flexibility is 60% higher than the original;
- Universality Verification: According to third-party testing, the three models can cover 98% of MAN's on-sale truck seats. A technician at a MAN truck 4S store commented: "Previously, we had to prepare 3 types of original cylinders to repair different series of MAN trucks. Now SW's three-model kit can handle it, reducing inventory pressure by half."

As the core component of High performance truck seat shock absorber, the product achieves a breakthrough in shock absorption performance:
- Cylinder Material: Uses 2.5mm thick 45# seamless steel pipe with a tensile strength of 600MPa. The impact resistance is 80% higher than the original cast iron cylinder, avoiding "cylinder deformation on bumpy roads";
- Damping Optimization: Built-in double-tube shock absorption structure, combined with high-viscosity shock oil (viscosity change ≤15% from -30℃ to 80℃), with a shock absorption stroke of 50mm, which can absorb 80% of high-frequency road vibrations. The vibration transmission rate is reduced from 60% (original) to 15%;
- Sealing Upgrade: Uses German imported fluororubber seals, which are oil-resistant and aging-resistant. The air tightness test shows a pressure drop of ≤0.01MPa after 2 hours of 1.0MPa pressure retention, completely solving the "3-month oil leakage" problem of the original rubber ring.
A test by a MAN TGX fleet showed that after installing this adjustment cylinder, the driver reported that "the seat bump feeling is significantly reduced when driving on gravel roads, and the waist does not ache after 6 hours of continuous driving."
To meet the needs of maintenance scenarios, Adjustment cylinder parts for MAN is fully optimized for installation convenience:
- Tool Simplification: Only basic tools such as wrenches and circlip pliers are needed. Remove 2 original fixing bolts and pull out the pneumatic plug to replace, no professional equipment required;
- Clear Positioning: The cylinder surface is printed with model marks and installation direction arrows to avoid shock absorption failure caused by reverse installation;
- Instant Effect: No air pressure calibration is required after installation, and it can be used normally after power-on and air supply, greatly saving vehicle downtime compared to the traditional "1-hour calibration" process.
To ensure the stable operation of High performance truck seat shock absorber in complex environments, the product is optimized for MAN truck usage scenarios in details:
- Dust-Proof Structure: The cylinder piston rod surface is hard chrome-plated (thickness 0.05mm), combined with a telescopic dust cover, which can block dust and gravel from mining areas and construction sites, avoiding seal failure caused by piston rod wear;
- Temperature Adaptation: The shock oil uses a wide-temperature formula, no solidification in -35℃ low temperature environment, no dilution in 85℃ high temperature environment, adapting to extreme temperatures in northern winters and southern summers.
- Overload Protection: When the cylinder bears a pressure exceeding 1.2MPa, the built-in pressure relief valve automatically vents, avoiding cylinder burst and damage to the seat shock absorption system;
- Status Prompt: A transparent oil level observation window is installed on the top of the cylinder, which can directly check the shock oil stock and replenish it in time when oil is insufficient, reducing sudden failures.
Produced by a factory certified by IATF 16949, each 81623406036/81623846008/81623406035 cylinder undergoes three tests before leaving the factory:
- Shock Absorption Performance Test: Simulate 100,000 bump impacts, damping force attenuation ≤10%;
- Air Tightness Test: 1.0MPa pressure retention for 2 hours, no air leakage, no pressure drop;
- Environmental Test: Static placement at -35℃ low temperature and 85℃ high temperature for 48 hours each, with normal functions.
III. Scene Adaptation: Covering Core Operation Scenarios of MAN Trucks
Whether for long-haul logistics or engineering mining, this 81623406036 81623846008 81623406035 truck parts can accurately match needs:
1. Long-Haul Logistics: Shock Absorption Protects Waist and Reduces Fatigue
The MAN TGX/TGS series is often used for inter-provincial long-haul transportation, with an average daily driving distance of over 800km. A logistics fleet reported that after installing this cylinder, the driver's lumbar fatigue complaint rate dropped from 40% to 12%, and the driving efficiency increased by 15%.
2. Engineering and Mining Transportation: Durable and Less Maintenance
Mining roads have many gravels and severe bumps, and the original cylinder needs to be replaced every 6 months on average. A test by a Shanxi MAN TGS engineering fleet showed that the SW cylinder still had no oil leakage or shock absorption attenuation after 12 months of use, and the maintenance frequency was reduced by 80%.
3. Old Vehicle Renovation: Low-Cost Performance Restoration
For MAN trucks with more than 3 years of service, replacing the SW three-model cylinder costs only 1/3 of the original parts, and the seat shock absorption effect can be restored. A used car dealer said: "After installation, the seat comfort is comparable to that of a new car, and the vehicle residual value increases by 8%."
