Upgrade your Detroit Diesel Series 60 engine with the Kustom Truck Front Engine Upfit Kit, designed to convert from dual V-belts to a high-performance 10/8 groove serpentine belt configuration. This kit enhances power transmission, reduces belt slippage, and extends belt life, optimizing engine efficiency and performance. Commonly compatible with Kenworth trucks (e.g., T660, T800) and Peterbilt 386 models, it’s not chassis-specific, offering versatile fitment for Class 8 trucks. Engineered for a 12.00" fan mounting height (center of crank to center of fan hub) and designed for use with a top-mount pad-style AC compressor and pad-mount alternator, the kit includes a comprehensive set of components: alternator/AC compressor mounting bracket, 8-groove AC compressor clutch and alternator pulley, 10-groove crankshaft pulley, tensioners, accessory drive pulley, and mounting hardware. Ideal for mechanics and fleet owners, this kit ensures reliable operation in custom builds or fleet upgrades. Note: For engines with accessory drive P/N 23523996, replace the dual V-belt pulley with the provided 8-groove serpentine pulley; for P/N 23509200, the shaft is 1/4" too short and requires shimming or replacement to align the belt properly. Confirm compatibility with your engine and fan mounting height by contacting Kustom Truck.
