Cummins Inc. has unveiled the new RPL35+, its lightest-ever driveline for Class 8 applications in the 21,500 lb.-ft. torque range.

The RPL35+ driveline will be available in the fourth quarter and was displayed in the exhibit hall at the Technology & Maintenance Council’s annual meeting in Nashville, Tenn.

The driveline offers an enhanced design that offers up to 28 pounds of weight reduction compared to the current RPL35. There are also simplified connection points compared to traditional flange designs, reducing system complexity. 

The design provides a durable driveline engineered to support the adoption of super-fast axle ratios. Cummins also said fleets will not see any change to maintenance practices, driveline performance, or functionality, ensuring a seamless transition from the existing RPL35.

“The new RPL35+ driveline addresses the market need for lighter weight, durable drivelines that can address the increasing adoption of down speeding and contribute to a positive total cost of ownership in both linehaul and heavy-duty trucks,” said Eric Lewandowski, senior product line manager at Cummins. “It also improves fleets’ serviceability needs and their demands for enhancements that help optimize labor and material costs.”
