Designed for Lifan powertrain systems, this drive shaft serves as a critical link in transferring engine torque to driven components, ensuring smooth and efficient power delivery. Crafted from SAE 1045 high-strength steel with precision machining (tolerance ≤0.05mm), it withstands torsional stress up to 850N·m and passes 100,000+ fatigue cycle tests (ISO 16130 standard). With electroplated anti-corrosion coating, it resists rust in harsh environments. Certified by ISO 9001, our shaft has supported over 15,000 aftermarket repairs globally, trusted by professional mechanics for its durability and precise fit.
Our drive shafts are crafted from SAE 1045 high-carbon steel, boasting a tensile strength of ≥600MPa—30% higher than industry-standard low-carbon alloys. Machined via CNC 5-axis centers with ±0.05mm tolerance, they eliminate vibration risks and ensure seamless power transfer. This precision engineering minimizes energy loss (efficiency ≥98%) and extends service life under heavy loads, making them ideal for high-stress aftermarket applications.
Engineered to handle peak torque up to 850N·m, our shafts outperform competitors’ average 700N·m limit. Validated through 100,000+ fatigue cycles per ISO 16130 standards, they resist cracking even under repeated shock loads (e.g., off-road acceleration). This performance is proven by 12,000+ units sold to European repair chains, with 97% customer feedback rating “zero failure in 2 years.”
Unlike standard single-coat options, we apply a zinc-nickel alloy base + epoxy-polyester topcoat, achieving 72-hour salt-spray resistance (ASTM B117) without white rust. Field data shows 40% longer service life in coastal regions vs. conventional shafts. This treatment also withstands chemicals (oils, brake fluids) common in garage workshops, reducing maintenance costs for end-users.
Reverse-engineered from Lifan’s original powertrain blueprints, our shafts replicate the exact spline count, length, and joint geometry of stock parts. This eliminates the need for custom modifications, reducing installation time by 50% for mechanics. Compatibility covers 90% of Lifan’s modern engines (2018–2025 production), ensuring broad market reach for distributors.
Each shaft undergoes 12 QC checkpoints, including 100% torque testing (±3% accuracy) and ultrasonic flaw detection. Our 0.3% defect rate (vs. industry avg. 2%) is validated by SGS audits. Backed by a 2-year warranty, we’ve served 80+ B2B clients globally, with 94% renewing orders for consistent quality.

Here are specific application scenarios of drive shaft:
Widely used by independent repair shops and fleet maintenance centers to replace worn or damaged original drive shafts. Its OEM-matched dimensional precision (±0.05mm tolerance) ensures 50% faster installation vs. generic alternatives, reducing workshop downtime. Field data shows 97% of repair clients report "zero rework needed" within 2 years, thanks to its 100,000+ fatigue cycle resistance (ISO 16130-tested), making it a top choice for cost-effective aftermarket solutions.
Ideal for commercial fleets (e.g., logistics trucks, utility vehicles) operating under frequent high-load conditions. With a max dynamic torque capacity of 850N·m, it withstands sustained heavy torque outputs (e.g., towing, loaded haulage) without deformation. Testing confirms it maintains structural integrity under 12-hour daily operation cycles, reducing replacement frequency by 40% compared to standard 700N·m shafts—critical for maximizing fleet uptime.
Adopted in industrial machinery (e.g., generators, hydraulic pumps, construction equipment) requiring reliable power transmission. Its zinc-nickel alloy + epoxy-polyester dual-coating resists chemicals (oils, solvents) and 72-hour salt-spray exposure (ASTM B117), ensuring 50% longer service life in dusty, humid, or corrosive factory environments. Precision machining (±0.05mm) guarantees seamless integration with industrial gearboxes, minimizing energy loss to <2% during power transfer.
Suited for non-paved terrain applications (e.g., agricultural machinery, off-road utility carts) subject to shock loads and vibration. Engineered to endure 100,000+ impact cycles (±300N·m amplitude), it resists cracking even under extreme jolts (e.g., rock crawling, uneven ground). Field feedback from outdoor equipment dealers shows 92% user satisfaction for reducing "vibration-related component wear," enhancing operational safety in rough conditions.
1.Pre-Installation Check: Verify dimensional compatibility (±0.05mm tolerance) with your Lifan powertrain interface using our included calibration gauge. Ensure no burrs or debris on connection points.
2.Installation Steps: Align the shaft’s spline with the gearbox/drivetrain hub, maintaining ≤3° angular deviation. Hand-tighten bolts first, then use a torque wrench to secure to 120N·m (per ISO 16130 recommendation)—over-tightening risks spline damage.
3.Post-Installation Test: Run the powertrain at low RPM (500–1,000) for 5 minutes to check for unusual vibrations. Our QC report confirms this reduces early wear by 60%.
4.Maintenance Tip: Inspect splines and coating quarterly; reapply anti-corrosion spray if exposed to harsh chemicals. Follow these steps to maximize service life (tested to 100,000+ cycles).
