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:

Domax^® 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 Domax specifications.
  

Domax-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.

Rear RacePac Enhanced and Tested for Stronger Performance

• Benchmarked against the existing RacePac, we enhanced the robustness and conducted successful 12-hour internal rig tests.
• History shows that successful testing is an indicator of stronger performance regardless of car setup or track.
• Multiple tests completed designed to optimize grease fill, lubricant retention, bearing setting and enhanced bearing internal geometry.
• More durable and lighter hub with less unsprung weight on the rear axle.
• Reduces the amount of cooling needed for rear hubs which can enable additional aerodynamic adjustments.
