Description

Hybrid Racing Aircraft Bearing Shift Knob

This shift knob weighs approximately 425 grams. That's more than 3x the weight of an equivalently sized 6061 aluminum knob and nearly 2x as much as an equivalently sized titanium knob. These knobs start out as a 1.875" aircraft grade ball bearing made from E52100 Alloy Steel. These aircraft bearings have a diameter tolerance of plus or minus two ten thousands of an inch. The shiny appearance you see on the outside of the knob is not chrome plating. E52100 Alloy Steel is also known as "chrome steel" and has such a high chromium content that it has this same appearance through its entire thickness. The metal is so hard (RWC60) that it can not be threaded, so Hybrid has to drill out the bearing and press in a threaded stainless steel rod. Finally, the knob receives a high polish and is laser engraved with the "hr" logo and "Hybrid-Racing" text.
