Bearing spacers are a significant upgrade that improves wheel spin by over 1200% while improving the longevity of your wheel bearings. When properly installed they 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. (We recommend 20-40 ft lbs.) 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 Adjustable Bearing Spacers are covered under US Patent No 3,312,162.
