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.

As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize drivetrain components that offer "drop-in" OE reliability. This unit serves as a direct professional-grade replacement for Volvo part numbers 85003114, 85003973, and assembly number 24157502. By upgrading to this OE-level assembly, you maintain the precise spline count and actuation quality necessary for your I-Shift or mDrive system to operate at peak factory performance for hundreds of thousands of miles.
