The Big Block Chrysler (383–440 & 426 Hemi) All-Inclusive Style Track Serpentine System from March Performance delivers the perfect balance of performance, reliability, and visual appeal for Mopar engines. Designed specifically for Chrysler big block and Hemi applications, this 6 rib serpentine system features a precision-engineered one-piece alternator and A/C bracket that provides unmatched rigidity and alignment. Four strategically placed idlers maximize belt-to-pulley contact for true no-slip performance, even under high load. Each component is CNC-machined in the USA from 6061-T6 billet aluminum, ensuring aerospace-level strength and precision fitment. The included belt tension adjustment tool simplifies setup and maintenance, while the maintenance-free powder coat finish—available in clear, black, black onyx, or chrome—eliminates the need for polishing. With a 140-amp chrome alternator, Sanden 7176 A/C compressor, and a larger diameter crank pulley for improved accessory drive, this serpentine kit enhances both form and function. Backed by March Performance’s reputation for American-made quality, the Style Track system is the ultimate upgrade for your Chrysler 383–440 or 426 Hemi engine.
