0501 328 495 Spline Sleeve

Part No. 0501 328 495 is a spline sleeve, a key transmission component for the mainshaft gear shift of ZF 12-speed AMT transmissions. It connects mainshaft power and cooperates with the sliding sleeve to complete synchronous gear shifting.
Manufactured strictly in accordance with OEM process and tolerance standards, it features precise spline module and tooth pitch as well as high coaxiality, ensuring stable operation without eccentric wear.
Made of impact-resistant material that withstands long-term alternating loads, it is suitable for heavy-duty trucks and passenger vehicles equipped with ZF 12AS2330, 12AS2530, 12AS2730 and other models.
It effectively resolves faults such as spline wear, loose fit with sliding sleeve, difficult gear engagement, jumping gear and abnormal noise. After installation, it delivers reliable power transmission and smooth gear shifting.

This ZF 0501 328 496 spline sleeve is compatible with ZF 12AS series 12-speed AMT transmissions.

It is integrally precision-machined from high-strength alloy steel and strengthened by carburizing and quenching, featuring high overall hardness, excellent torsion and wear resistance, and resistance to tooth chipping and deformation.

The internal spline teeth are precisely formed with uniform fitting clearance, meshing accurately and smoothly with the mainshaft and sliding ring for jitter-free and rattle-free gear shifting.
It resists transmission oil corrosion and high-temperature fatigue, maintaining stable load-bearing capacity without looseness under heavy-duty and frequent shifting conditions. Made to precise OEM dimensions for easy alignment during installation, it is a high-quality core replacement part for the maintenance of transmission shifting and transmission mechanisms.
