PACCAR Launches Proprietary Axle in North America

PACCAR is launching a new proprietary tandem axle that is the industry’s lightest and most efficient axle in its class. “PACCAR is pleased to deliver the most fuel efficient axle in the industry to complement the superior performance and fuel economy of our PACCAR MX Engines,” said Landon Sproull, PACCAR vice president.

The new PACCAR axle is designed to improve the operating efficiency for line haul, regional haul and pick-up and delivery customers. The new axle is rated at 40,000 pounds, supporting a gross combination weight of 80,000 lbs. Kenworth will begin offering the axle to customers in January 2017. “PACCAR’s axle reduces vehicle weight by up to 150 pounds, and provides improved fuel economy,” noted Sproull.

The PACCAR axle features a unique pinion-through-shaft design that simplifies power flow in the axle for maximum efficiency. The PACCAR axle also incorporates an innovative laser-welded carrier design that reduces weight and improves fuel economy. The PACCAR axle comes with an industry-leading warranty of five years or 750,000 miles.

The PACCAR axle offers ratios from 2.47 to 3.70 with engine torque compatibility up to 1,650 lb.-ft. and multitorque rating compatibility up to 1,750 lb.-ft.
