Advanced AMT Performance: The OE Volvo I-Shift Clutch Assembly Advantage
This OE Volvo I-Shift Clutch Assembly (Part # NMU359-280-12) features a robust 430mm x 50mm stamped-steel, single-plate design specifically calibrated for the unique actuation cycles of Volvo and Mack automated systems. Engineered to eliminate the sluggish engagement and "clutch drag" often found in worn-out units, this assembly ensures consistent, lightning-fast gear changes and optimal fuel efficiency. Note: With a massive torque rating of approximately 1,850 lb-ft, this kit is built to handle the immense pulling power of the Volvo D13 and Mack MP8 engines without premature slippage.

This unit serves as a direct professional-grade replacement for Volvo part numbers 85003114, 85003973, and assembly number 24157502.
