The Permalube RPL Series driveline was first in the North American heavy-duty commercial vehicle industry to be permanently lubricated and sealed for life to reduce maintenance and save money for cost conscience fleets. Advantages include reduced operating and maintenance costs, industry-leading warranties, easy serviceability and extended U-joint life, particularly on gear-fast/run-slow drivetrains and higher torque applications. Designed to accommodate linehaul, heavy service and downspeeding, these drivelines fit a wide range of applications and torque handling requirements.
