Introduction

The 1701030 Fast Input Shaft is a core high-precision transmission component specially designed for heavy-duty truck gearbox systems. As the front power input core of the gearbox, it undertakes the key task of transmitting engine power into the transmission assembly, realizing high-speed power output and gear shifting transmission. Adopting high-grade alloy steel and integral forging and precision grinding process, this input shaft features high overall strength, excellent torsion resistance and stable high-speed operation performance. It effectively avoids common gearbox faults such as power transmission lag, abnormal noise, shaft shaking and shaft breakage caused by worn, deformed or fatigued original shafts. It ensures smooth gear shifting and stable power transmission of heavy-duty vehicles during long-distance driving and heavy-load operation, serving as a reliable OEM replacement part for truck gearbox maintenance and overhaul.

Key Features

✅️100% OEM Exact Matching Manufactured strictly in accordance with original factory technical standards with standard part number 1701030. The overall shaft length, gear tooth parameters, spline size and installation tolerance fully conform to original gearbox specifications. No modification or adjustment is required for direct assembly, perfectly matching heavy-duty truck gearbox installation standards.

✅️High-Strength Alloy Forging Material Made of premium alloy steel with integral forging and multiple heat treatment processes including quenching and tempering. The shaft body boasts ultra-high hardness, strong torsion resistance and bending resistance, which can withstand long-term high-speed rotation and heavy-load torque impact, not easy to deform, twist or fracture.

✅️Precision Tooth Grinding & Stable Transmission Adopts advanced CNC precision tooth grinding and fine finishing technology. The gear teeth and spline surface are smooth with accurate meshing clearance, ensuring precise meshing and sensitive power transmission. It effectively eliminates transmission jitter, gear jumping and power loss, realizing stable and efficient gearbox operation.

✅️Excellent High-Speed & Fatigue Resistance Optimized structural design and professional stress relief treatment ensure outstanding high-speed operation stability and anti-fatigue performance. It adapts to long-term high-frequency shifting and continuous high-speed driving conditions, effectively delaying component aging and extending service life.

✅️Low Failure Rate & Improve Gearbox Performance Strict dynamic balance testing and precision size inspection ensure zero deflection during operation. It solves common problems such as gearbox abnormal noise, weak power output and unsmooth shifting caused by damaged input shaft, fully restoring the original transmission performance of the gearbox.

✅️Cost-Effective Aftermarket Solution Factory direct supply with full quality inspection, reaching OEM original quality level with competitive price. Widely applicable to various heavy-duty truck gearbox models, it is a high-cost-performance replacement part favored by repair shops, fleets and spare parts wholesalers in global overseas markets such as Middle East, Africa and Central Asia.
