Lightweight RacePac® Front and Rear Wheel End Assemblies
For stronger performance, we re-engineered RacePac wheel end assemblies to enhance speed and performance on all types of tracks while increasing your team’s efficiency in the shop.
Design Attributes:
Timken® RacePac® Tapered Roller Bearings*
30% cooler operating temperatures**: Improved internal geometry reduces sliding contact stress and provides consistent rolling torque.
Reduce bearing replacement costs: Enhanced durability due to lower operating temperatures.
Improved drivetrain efficiency: Reduced bearing power loss results in a cooler running hub.
Ready to install: Bearings pre-lubed, pre-set and pre-assembled to Timken specifications.
Timken-Designed Zero-Torque Seal*
Excellent performance: Seal works off positive air pressure, keeping contaminants out.
More horsepower potential due to less seal drag.
Hubs
More speed: 2 pounds lighter (8 pounds total unsprung weight reduction). Meets minimum weight requirement of 6.25 lbs.
Durability maintained with lightweight design.
Grease Containment Dams
Maintain proper lubrication: Keeps grease in critical areas; additional grease dam in the rear hub helps reduce operating temperatures.
Engineered Spacers
Reduces setup time and increases stiffness: Precise design helps optimize bearing setting.
*Available exclusively in RacePac. ** Rear bearing rig testing.
