Overview

The March Performance 10050 is a 3-piece V-belt pulley kit designed for Mopar 383, 440, and 426 Hemi engines from 1970 and later. This kit features a performance ratio with 2-groove pulleys for the water pump and crankshaft, and a 1-groove pulley for the alternator. It is precision CNC-machined from 6061 T-6 aluminum for strength and durability, finished with a clear powder coat for a lasting appearance without requiring polishing.

This pulley set is engineered to reduce parasitic accessory drag, which can typically result in up to 12 horsepower gains at the rear wheels and helps prevent belt throwing. The pulleys are designed for normal street driving, ensuring reliable operation and improved performance.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
