Dongfeng KL truck parts Rubber bushing for stabilizer bar 2906039-T38V0

Crafted from a specialized EPDM (Ethylene Propylene Diene Monomer) rubber compound with 15% carbon black reinforcement, the bushing delivers exceptional elasticity and vibration absorption. With a Shore A hardness of 65±5, it balances rigidity (to maintain stabilizer bar position) and flexibility (to cushion shocks from road bumps), reducing vibration transfer from the suspension to the chassis by 40%. The rubber compound’s high rebound rate (≥80%) ensures it quickly recovers shape after compression, preventing permanent deformation even under continuous stress (e.g., long drives on uneven roads). Unlike hard rubber bushings that transmit excessive vibration or soft ones that allow bar misalignment, this optimized compound maintains stable performance across temperatures from -40°C (freezing winters) to 120°C (hot engine bay heat), ensuring consistent handling in all weather

Engineered to withstand harsh automotive environments—UV radiation, oil, grease, and road chemicals—the bushing integrates anti-aging additives and chemical-resistant properties. The EPDM rubber is infused with UV stabilizers and antioxidants that prevent cracking, hardening, or brittleness, passing 1,500 hours of xenon arc testing (simulating 6 years of sun exposure) without degradation. It also resists swelling or softening when exposed to engine oil, transmission fluid, or road salt (swell rate ≤5% after 72 hours of immersion in oil), maintaining structural integrity for 5+ years. Unlike natural rubber bushings that deteriorate within 1–2 years, this EPDM construction ensures long-term reliability, reducing the need for frequent replacement and lowering maintenance costs

Designed to protect the stabilizer bar and bushing inner hole from dust, gravel, and moisture, the bushing features an integrated sealed flange design. The top and bottom flanges (8mm thick) extend outward by 5mm, creating a tight seal against the mounting bracket’s surface—blocking debris from entering the gap between the bushing and bar. Additionally, the inner hole is coated with a low-friction silicone layer (0.1mm thickness) that reduces sliding friction between the bushing and stabilizer bar, minimizing wear caused by bar movement during steering or suspension compression. This dust-proof and low-friction design prevents abrasive particles from accelerating wear, extending the bushing’s service life by 30% compared to non-sealed alternatives and ensuring smooth stabilizer bar operation

Designed for hassle-free replacement by technicians or DIY owners, the bushing simplifies installation and works seamlessly with the truck’s original hardware. It requires no specialized tools—installation involves removing the old bushing, applying a small amount of silicone grease (included with the bushing) to the inner hole, and pressing the new bushing into the mounting bracket until it seats firmly (audible “click” indicates proper installation). The bushing is compatible with the Dongfeng KL’s original stabilizer bar mounting bolts (M12×40mm) and lock washers, requiring no modifications to the bracket or bar. Its flexible yet durable structure allows for slight dimensional variations in older brackets (common in high-mileage trucks) without compromising fit. Each unit undergoes compression testing (10,000 cycles at 500N force), hardness testing, and seal integrity checks, backed by a 18-month warranty against defects (e.g., cracking, hardening, flange deformation)
