hubpilotill   Are you experiencing any of the following?
  • Wheel Vibrations?
  • Wheel Hop?
  • Brake Pedal Pulsation
  • Erratic Tire Wear?
  • Excessive Fuel Consumption?
You may have an off center wheel due to hub pilot spacing. Due to the weight of the wheel, the upper and lower pilots allow some space between the wheel stud and the wheel. This can cause an "egg-shaped" motion to occur which could cause the above ride quality issues. SPC offers a full line of tools and leave on solutions for a variety of vehicles.

Wheel Centering Tools
These tools slide directly over the wheel studs in the 12, 4, and 8 o'clock positions. The wheel is then installed over the tools, the stud nuts added to the exposed studs and tightened. The wheel is now centered precisely. The centering tools are removed and the final stud nuts are added - torquing all nuts to mfg. specifications. For more click here.
