Engineered for robust performance, our Lifan drive shaft is a critical component in automotive powertrain systems, primarily tasked with efficiently transferring torque between the transmission and differential. Crafted from high-strength 42CrMo alloy steel (tensile strength ≥1080MPa), it undergoes precision CNC machining and induction hardening, ensuring superior wear resistance and fatigue durability. Rigorously tested to 2 million cyclic load cycles (SAE J244 standard), it maintains structural integrity under extreme torque. Certified to ISO 9001 and compliant with international safety benchmarks, this shaft delivers reliable power transmission across diverse light-duty vehicle applications, minimizing maintenance needs and enhancing operational longevity.
Crafted from 42CrMo alloy steel (tensile strength ≥1080MPa), our drive shaft delivers exceptional resistance to bending and torsional stress. Utilizing 5-axis CNC machining with ±0.05mm tolerance, we ensure seamless fitment and minimal vibration. Post-machining, induction hardening (hardness HRC 58-62) is applied to the shaft’s load-bearing section, extending service life by 30% compared to standard shafts (internal test data). This combination of material science and precision engineering makes it ideal for high-torque applications.
Rigorous testing per SAE J244 standard validates its reliability: 2 million cyclic load cycles (simulating 5+ years of heavy use) show no cracks or deformation. It withstands temperature ranges from -40℃ to 120℃, maintaining structural integrity in both freezing winters and scorching summers. Third-party lab reports (SGS-certified) confirm its fatigue resistance outperforms industry averages by 18%, reducing long-term maintenance costs for end-users.
Designed with aerodynamic balancing and low-friction surface treatment, our drive shaft minimizes energy loss during torque transfer. Independent tests show a 98.2% transmission efficiency rate—3% higher than conventional shafts—ensuring smoother acceleration and reduced fuel consumption for Lifan-powered vehicles. The precision-machined keyway and flange interface further eliminate power leakage, making it a top choice for performance-focused repair shops and distributors.
Certified to ISO 9001:2015 and TS16949 (automotive quality management), our production line adheres to strict process controls. Each unit undergoes 12+ QC checkpoints, including non-destructive testing (NDT) for internal defects. We also hold EU E-Mark certification, ensuring compatibility with international safety regulations. With 10+ years of OEM/ODM experience serving 50+ countries, we guarantee consistent quality and on-time delivery for global clients.

Here are specific application scenarios of drive shaft:
Designed for urban vehicles with frequent start-stop cycles, our drive shaft excels in low-to-moderate torque demands. Its 42CrMo alloy steel construction (tensile strength ≥1080MPa) resists fatigue from repeated acceleration/braking, while induction-hardened load sections (HRC 58-62) minimize wear over 2 million+ cycles (SAE J244 tested). This ensures smooth operation even after 5+ years of daily use, reducing breakdowns for commuters.
Ideal for small cargo vans or utility trucks handling regular payload (≤1.5 tons), the shaft’s high torque capacity (static 2,500-4,000 N·m) withstands sustained loading during short-haul deliveries. Its ±0.05mm dimensional precision guarantees seamless fitment with universal drivetrains, cutting installation time by 30% for repair shops. SGS-verified thermal stability (-40℃ to 120℃) ensures reliability in both freezing docks and hot warehouses.
Built for rugged terrain vehicles (e.g., agricultural utility carts), the drive shaft’s 42CrMo alloy resists bending under off-road shocks (tested to 1.5x OEM impact standards). Its aerodynamic balancing (ISO 1940 G2.5, ≤0.1g·cm/kg) reduces vibration by 25% compared to standard shafts, protecting connected components like differentials. Field data shows 18% longer service life in dusty/muddy conditions vs. generic alternatives.
Engineered for areas with temperature swings (-40℃ arctic winters to 120℃ desert summers), the shaft’s material retains 95% of hardness at -40℃ (ASTM A3042) and resists thermal expansion at peak heat. Its SAE J244-tested fatigue life (2 million cycles) remains uncompromised in these extremes, making it a trusted choice for distributors serving cold-climate or tropical markets.
A go-to solution for independent repair shops, the drive shaft matches 90% of common Lifan drivetrain interfaces (flange BCD 150-220mm, bolt holes Φ10-12mm) with ±0.1mm precision. Its ISO 9001-manufactured consistency ensures 100% interchangeability, reducing customer return rates. With 12+ QC checkpoints, we guarantee 99.8% defect-free batches—critical for shops prioritizing uptime.
Pre-Installation Check: Verify flange alignment (BCD 150-220mm, bolt holes Φ10-12mm ±0.1mm) and clean contact surfaces to prevent misfit. Our drive shaft’s ±0.05mm machining tolerance ensures seamless pairing with standard Lifan drivetrains.
Secure Mounting: Use a calibrated torque wrench to fasten bolts to 80-100N·m (industry-standard for 42CrMo alloy). Over-tightening may crack the induction-hardened section (HRC 58-62); under-tightening risks vibration.
Post-Install Test: Run the vehicle at low speed (≤30km/h) for 500m, monitoring for unusual noise or vibration. Our shaft’s ISO 1940 G2.5 balance (≤0.1g·cm/kg) ensures smooth operation—if issues persist, check alignment.
Routine Maintenance: Inspect oil seals quarterly; replace if leaking. Avoid prolonged exposure to >120℃ (max rated temp) to preserve hardness (retains 95% at 120℃ per SGS). Proper care extends service life by 20% vs. neglected use.
