Frequently Asked Questions

Q: Why is a spherical bearing like the COM-6 insert important for quarter midget spindles?

A: The COM-6 spherical insert allows for self-alignment. In high-speed racing, chassis flex can cause binding in standard rigid bearings; this design compensates for that movement, ensuring your steering remains smooth and responsive throughout the entire cornering arc.

Q: How do I know if my spindle bearing needs to be replaced?

A: You should inspect your spindle bearings regularly for any signs of play, "notchy" movement, or grinding noises. If you notice increased steering friction or if the front-end geometry feels inconsistent during track sessions, it is time to replace the bearing to maintain optimal handling.

Q: Is this 3/8" spindle bearing compatible with all kart chassis?

A: This bearing is specifically engineered for 3/8" spindle shafts common in quarter midget racing. Please verify your spindle diameter before purchase to ensure a proper fit, as improper sizing can lead to steering slop or safety issues.
