Marmon-Herrington announced Wednesday at the North American Commercial Vehicle Show (NACV) in Atlanta that it has been chosen to supply Sisu axles for Western Star’s 4900, XD-25 model.
Marmon-Herrington says the XD-25 is a “Productivity Machine” and its Sisu planetary axles allow Western Star to achieve maximum durability and reliability without the high-speed limitations of other planetary axles
The Western Star 4900, XD-25 is an extreme-duty machine that delivers 25 tons of capability and is equipped with a Detroit engine that delivers up to 560 HP and a peak torque of up to 1850 lb.-ft. The Sisu FR2P32 planetary axles are responsible for delivering the XD-25’s massive engine torque to the ground. Marmon-Herrington says this high-speed tandem boasts a 70,000 lb. GAWR (gross axle weight rating) combined with top speeds of approximately 65 miles per hour.
“Western Star chose Sisu for the XD-25 due to Sisu’s reputation and dedication to robustness and quality,” says John Tomlinson, XD & Vocational Sales Manager for Western Star. “This truck represents the durability and ruggedness needed within the construction and off-road hauling markets. We are excited to have Sisu as a part of the XD Series family and know they are the perfect choice for meeting the XD-25’s stringent requirements.”
Sisu axles are engineered using only premium components to provide optimum performance and reduced maintenance for extended product life. Marmon-Herrington says the double reduction, high-speed planetary axles come in a variety of ratios ranging from 4.11 to 12.53 and provides up to 600,000 lb. GCWR (gross combination weight rating). Marmon-Herrington stocks certain components and assembles the XD-25 axles in its manufacturing facility in Louisville, Ky.
“Sisu axles first became available from Marmon-Herrington in 2011. Since then, our companies have collectively taken this product to the next level,” says Dan Souhan, sales and marketing director for Marmon-Herrington. “By offering the industry’s only Rapid Response Program, Marmon-Herrington is able to deliver key products in 30-days or less. This program has aided greatly in allowing our customers to win new business and we are excited to offer Sisu axles as part of this program.”
