DRP Performance Wheel Bearing and Hub Assembly

DRP Performance Wheel Bearing & Hub Assembly: Race-Proven Low-Drag Technology

When milliseconds and fractions of a horsepower separate winners from the rest of the field, hub friction is not something a serious racer can ignore. DRP Performance has built its reputation squarely on solving that problem, and their wheel bearing and hub assembly products represent some of the most rigorously engineered solutions in circle track racing today.

DRP Performance, located in Rocky Mount, Virginia, designs, manufactures, and sells premium-quality components for the automotive racing industry. The brand specializes in circle track stock car racing, supporting teams at every level — from local short tracks to NASCAR and major national series competitors. Within that world, DRP’s hub and bearing components are among the most trusted upgrades a team can make.

The Hub Defender System: A Measurable Edge

At the center of DRP’s wheel bearing lineup is their flagship Hub Defender bearing spacer system. Designed to reduce friction and help the car roll faster, Hub Defender bearing spacers are engineered to increase wheel speed by over 1,200 percent, allow bearings to run cooler, and reduce hub maintenance. These aren’t marketing claims — DRP backs them with rigorous testing using data acquisition, custom test fixtures, and on-track validation.

Bearing spacers are used in virtually every application in professional motorsports and make the most difference of any low-drag hub upgrade. DRP Bearing Spacers feature a threaded adjustment, allowing the user to quickly set bearing end play or preload, while a set-screw locks the spacer at the desired setting. Once dialed in, the spacer holds its adjustment through normal racing use and does not need to be reset unless the hub or bearings are replaced.

Complete Low-Drag Hub Kits

For teams looking for an all-in-one solution, DRP offers complete Hub Defender Low-Drag Hub Parts Kits. These innovative kits virtually eliminate wheel bearing drag, delivering reduced friction and lower operating temperatures — ultimately putting more horsepower to the track — while also reducing maintenance intervals. Each kit includes premium-finished wheel bearings, an ultra low-drag hub seal, and a special adjustable wheel bearing spacer for precise preload setting.

Hub Defender kits are available for a wide range of popular racing applications, including 5x5 rear setups, the Deuce 1/2, GM Metric Front, and Mustang II/Pinto front spindles — making it straightforward to find the right solution for your specific platform. DRP also offers components individually for teams that prefer to source or upgrade specific parts of their hub system.

Super-Finished Bearings for Lower Rolling Resistance

DRP doesn’t just stop at spacers. Their bearing kits feature REM Super-Finished bearings and races, a surface treatment that measurably lowers rolling resistance compared to standard bearings. Whether you need bearings for Wide Five hubs, 6-pin front hubs, or other common racing applications, DRP offers premium finished bearing and race kits engineered specifically for low-drag performance.

DRP builds custom test fixtures, uses data acquisition, computer modeling, and track testing to determine if a product really is better and by how much — because they believe it is their job to bring racers the truth, not just an opinion. That philosophy is evident in every component of their wheel bearing and hub assembly lineup.
