DRP Performance Premium Low Drag Bearing Kits
DRP Performance offers premium low drag bearing kits for a wide range of applications, including many Ford, Chevy, and Pontiac cars from the 1960s, '70s, '80s, and '90s. Low drag hub components reduce friction and lower temperatures, making your wheels spin easier, delivering more horsepower to the track—all while reducing maintenance and making your race car faster. Enhance your performance on oval track asphalt, oval track dirt, drag racing, road racing, and street applications. Kits include a DPR bearing spacer, DRP Premium Super finished Bearing Kit, and DRP Ultra low drag seal. Here are details on each component: * DRP Bearing Spacer: A difference you can feel—in the pits and on the track. Bearing spacers make the most difference of any low drag hub upgrade. Properly installed, these spacers will provide an immediate increase in hub free spin, an improvement large enough to feel just by pushing the car around. And the benefit doesn't stop there. Bearing spacers make the most difference when a side load (cornering force) is applied. Drivers have commented on how much faster a car with bearing spacers free rolls when entering and through the center of the corner. Bearing spacers simplify and reduce hub maintenance. Spindle nut torque is no longer sensitive. In fact, with spacers installed, you can tighten the spindle nut as much as you want without overtightening the bearings. (DPR recommends 20-40 lbs.-ft.) Bearings will run cooler and do not need to be repacked as often. Bearing spacers are simple to install. DRP bearing spacers have a threaded adjustment, allowing the user to quickly set bearing end play or preload. A set-screw locks the spacer at the desired adjustment. Once installed, they do not need to be readjusted unless you replace the hub or bearings. Bearing spacers are used in virtually every application in professional motorsports. * DRP Premium Super finished Bearing Kit: Reduce bearing temperature by over 100 degrees F verses stock bearings! Increase free spin by over 250 percent! DPR starts with premium quality bearings and puts them through a super finishing process. This process removes the grind marks and greatly smooths the surface of the bearing roller, while leaving a "hatch" pattern to retain grease. Quality wheel bearings will last the life of most racing applications. * DRP Ultra Low Drag Seal: …billet aluminum, full PTFE sealing lip, reusable, great for any application: dirt, asphalt, road race, street Decrease seal drag by over 1,000 percent! Air gap seals create an "air curtain" to keep debris out and eliminate drag completely! DRP Ultra Low Drag hub seals are true, purpose-built, high performance seals. The housing is made from lightweight aluminum. The sealing element is a special PTFE blend, giving it natural low friction qualities. Seals are reusable. Order the kit recommended for your vehicle.
