Marmon-Herrington Supplies Western Star’s 4900 XD-25 with Industry Leading, Proven Sisu Axles
Louisville, Ky. (September 27, 2017)
Marmon-Herrington announced today that it has been chosen to supply Sisu axles for Western Star’s 4900, XD-25 model. The XD-25 is a "Productivity Machine" and Marmon-Herrington’s 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, monster 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. 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," said 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. 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," said Dan Souhan, Sales & 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."
Marmon-Herrington will display an XD-25 at its booth during the 2017 ICUEE Show (October 3-5) in Louisville, KY. Marmon-Herrington’s booth number is L384.
