Meritor is adding the RPL35 and RPL35SD drivelines to its Permalube RPL family of truck drivelines designed for heavy service applications.
“The RPL35 and RPL35SD expand upon the proven Permalube RPL family with their high-torque capacity designed for engine downspeeding and heavy service applications,” said Ken Lang, senior product line manager at Meritor.
The RPL35 is designed to be combined with the RPL25 inter axle, making it capable of handling higher torque imposed on drivelines from downspeeding engines for fuel economy in linehaul use. Downspeeding uses direct drive transmissions and fast axle gear ratios to maintain vehicle road speed at lower engine rpm.
The RPL35SD is designed for heavy-haul and three-axle applications with GCW ratings from 140,000 to 190,000 pounds.
Both drivelines incorporate European-style flange connections for secure transfer of torque and easier installation and removal. They are designed to help fleets increase efficiency and durability and can be combined with a five-year, 500,000 mile warranty, according to Meritor.
