  • Brand: OEM / Premium Aftermarket (Industrial-Grade Quality)
  • Product Type: Heavy-Duty Suspension Air Spring Assembly

Core Adaptation Information

  • Compatible Vehicle Types:
    • Medium/heavy-duty trucks (N2/N3 class), construction aggregate trailers, gravel transport vehicles, crushed stone haulage trucks
    • Off-road construction site material carriers, quarry logistics vehicles, and short-haul engineering transport fleets
    • All commercial vehicles equipped with air suspension systems matching the assembly’s mounting dimensions and off-road load requirements
  • Cross-Reference Models: CS-77 04 0801, CS-77 04 0811 (same-series off-road air springs)

Core Product Advantages

  • Robust Off-Road Load-Bearing Capacity: 5-ply reinforced structure with polyester cord reinforcement supports up to 9,500 kg per assembly, resisting deformation even under 120% overload or extreme off-road impact conditions—critical for aggregate and gravel transport.
  • Superior Shock Absorption for Rough Terrain: Optimized bladder geometry and medium-high pressure design effectively filter impacts from construction site ruts and quarry roads, reducing chassis vibration by 44% and preventing cargo spillage during transit.
  • Abrasion & Debris Resistant Durability: The anti-scuff coating on the CR rubber bladder protects against gravel and rock abrasion; galvanized fasteners resist rust from construction site mud and moisture, extending service life by 36% compared to standard aftermarket parts.
  • Fleet-Friendly Quick Installation: Standardized mounting interface enables direct bolt-on replacement, eliminating chassis modification and cutting maintenance time by 50% for construction fleet teams, minimizing vehicle downtime.
  • Wide Temperature Adaptability: Operates stably in extreme cold (-45℃) and high-temperature (+95℃) environments, suitable for cross-regional construction projects in frigid northern and high-heat southern regions.
  • Global Market Compliance: Meets ISO 16949 and ECE R134 standards, ensuring market access in Europe, North America, Southeast Asia, and other key regions for construction and off-road commercial vehicle parts.

Applicable Scenarios

  • Construction Aggregate Logistics: Ideal for gravel, crushed stone, and sand transport trucks and trailers, withstanding rough quarry access roads and frequent load cycles without bladder damage.
  • Off-Road Construction Site Haulage: Suitable for construction material delivery vehicles operating on job-site ruts and uneven terrain, improving suspension reliability in harsh working environments.
  • Special-Purpose Vehicle Retrofits: Used in the modification of off-road construction trailers and quarry logistics vehicles to enhance suspension load capacity and abrasion resistance.
  • Mid-Heavy Load Fleet Maintenance: Cost-effective replacement solution for construction and quarry fleets, reducing long-term maintenance costs and vehicle downtime.
  • Aftermarket Parts Distribution: Core product for auto parts dealers specializing in construction and off-road commercial vehicles, compatible with multiple models and meeting diverse customer demands.
