Introduction

AZ9716310615 is an original standard Inter-Axle Drive Shaft designed exclusively for SINOTRUK heavy-duty trucks, fully compatible with HOWO, A7 and other mainstream heavy truck models. As a core power transmission component of the vehicle’s chassis drive system, it is installed between the front and rear axles, responsible for stably transmitting engine power and torque to each drive axle. Equipped with high-precision universal joint and spline telescopic structure, this drive shaft can adapt to the angle displacement and distance change generated by vehicle bumping and body shaking during driving. Manufactured with high-strength alloy steel and precision integral welding technology, it features strong torsion resistance, stable power transmission and excellent fatigue resistance, effectively ensuring continuous and efficient power output of the whole vehicle, reducing power loss, and adapting to long-distance, heavy-load and complex road transportation conditions.

Key Features

✅️OEM Original Precision Matching: Produced in strict accordance with SINOTRUK factory original dimensional standards and technical parameters. The AZ9716310615 inter-axle drive shaft has accurate flange position, standard mounting holes and precise spline tolerance. It is a direct replacement for original parts without cutting, drilling or secondary modification, realizing quick installation and perfect fitting with SINOTRUK heavy truck inter-axle transmission system.

✅️High-Strength Alloy Material & Torsion Resistance: Adopts high-density alloy steel pipe and thickened integral flange structure, processed by precision forging and seamless welding technology. The overall body is solid with high structural rigidity and strong torsion resistance. It can withstand high torque impact during heavy-load start, acceleration and climbing, effectively avoiding shaft body deformation, distortion and fracture, solving the common failure problems of ordinary drive shafts under long-term heavy-duty operation.

✅️Stable Power Transmission & Low Energy Loss: Optimized universal joint and spline matching structure ensures flexible angle adaptation and precise power transmission. It effectively reduces power friction loss and transmission jitter during operation, makes power output more uniform and smooth, improves vehicle driving power and fuel economy, and avoids abnormal vibration and power insufficient caused by poor transmission performance.

✅️Flexible Telescopic & Strong Road Adaptability: Adopts standard spline telescopic structure, which can automatically adjust the shaft length according to vehicle body jitter and axle displacement during driving. It perfectly adapts to uneven road surfaces, bumpy mountain roads and complex working conditions, effectively relieving structural stress and preventing shaft body jamming and damage, ensuring stable operation of the transmission system in all road scenarios.

✅️Excellent Wear & Corrosion Resistance & Long Service Life: The surface is treated with professional anti-rust paint and anti-oxidation process, and the internal spline and universal joint parts are equipped with high-quality wear-resistant accessories. It effectively resists rainwater erosion, mud corrosion and long-term high-speed friction wear, avoids rusting, aging and abnormal noise problems, greatly improves overall durability and prolongs the service life of the drive shaft assembly.

✅️High Fatigue Resistance & Low Failure Rate: Undergoes professional dynamic balance calibration and repeated torsion fatigue testing. The whole shaft runs smoothly without eccentric vibration, adapts to long-term high-speed driving and frequent heavy-load operation. It has strong structural stability and anti-fatigue ability, effectively reducing maintenance frequency and vehicle failure rate, and improving the overall attendance rate of transport vehicles.

✅️Cost-Effective & Reliable After-Sales Support: All products pass strict dynamic balance test, torsion test and appearance quality inspection, meeting OEM and industry quality standards. With standardized production and stable quality consistency, it supports retail and bulk wholesale, providing high-quality and cost-effective original matching spare parts for SINOTRUK heavy truck daily maintenance and after-sales replacement.
