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.

Many Sonnax clutch hubs are designed for the extra-duty requirements of drag racing with Powerglide and other GM transmissions, for instance. Machined from a high-quality medium carbon steel forging, most hubs will accept five friction discs for the added load capacity needed in high horsepower race cars. All splines and thrust surfaces are precision-machined to exacting tolerances, and the unique lube hole pattern is designed to reduce drag on the friction discs in low gear. Sonnax clutch hubs are also available with or without lightening holes to reduce rotational weight.

Bowler Performance All-in-One transmission wiring harnesses for the Tremec T-56 Magnum transmission comes equipped with all the connections pre-wired into one harness for a simple installation and ease of use. The small epoxy sealed controller is mounted to the VSS output using the existing bolt, and once the unit is powered up, you will be able to connect via Bluetooth to your Apple or Android smartphone using Bowler's free app. The app will give you the ability to customize the input and output settings for each feature to ensure proper operation in your vehicle. The perfect finishing touch for any Tremec T-56 Magnum conversion, Bowler's All-in-One harnesses eliminate the need for any additional equipment to operate the reverse lock out or generate the correct speedometer signals coming from your Tremec T-56 Magnum. Previously, you would have needed up to five separate parts to perform all the same functions wrapped one of these harnesses. The more technology we incorporate into our hot rods sometimes requires specific input signals to allow everything to function correctly. With the two speed outputs available in these harnesses, you can independently control the output of each one further eliminating any need for additional equipment and connections. Regarding the reverse lockout, Bowler has incorporated the same speed setting feature as the OEs into the All-in-One harnesses, giving you better control over when the lock out is triggered. Bowler's All-in-One harnesses give you much greater flexibility in the components you are able to use and require less time wiring everything up, providing an easier solution for setting up your Tremec T-56 Magnum transmission. Choose the harness version designed for your specific transmission make. Additional notes: * Harnesses utilize a small, built in, epoxy sealed box that will control each of the three functions with power and grounding for each function through a switched +12 V circuit and a wire connected to the negative battery post or engine block. * Control of the reverse lockout solenoid is based on a user defined speed setting (default is set at locked above 4 mph and unlocked at 0 to 3 mph), eliminating the need for a separate lock-out control box. * For your electronic speedometer, the harness is equipped with two speed sensor outputs; the speed sensor outputs generate a square wave signal that goes from about -5 to roughly +5 V, varying in frequency as the speed changes. * Output will automatically shift and give you 0 to +10 volts for EMC input needing positive only signal. * The two speed sensor outputs are completely independent and can be calibrated separately with any pulse count and ratio you want, and are able to drive any common speedometer, cruise control, or ECM. * Tremec T-56 Magnum reverse lock-out module VSS with dual output, pre-set as GM 40-pulse output on one and 16-pulse output on the other and can be adjusted with your iOS or Android device. * Includes wiring for reverse lights, reverse lock-out, and vehicle speed sensor.
