Chromoly… the utterance of the word conjures images of superhero strength. The word is derived from chromium and molybdenum, the two main alloying elements of the metal. Chromium brings three major benefits to the table: innate hardness, improved pliability during the quenching process, and outstanding corrosion resistance. Molybdenum also serves to increase the alloy’s hardness. When it...

Gear break-in consists of controlled heat cycling of the gear set in a way that properly seasons or hardens the gear’s contact surfaces. It is a series of test drives. These critical first few miles of drive time can be the difference between a gear-melting headache and years of carefree driving. Failure to properly break-in your gear set can result in damaged, failing gears and a complete...
Spider gears are primetime players inside the differential. Also known as satellite gears, spider gears rotate around the side gears in the differential carrier. Side gears may also be referred to as axle gears or planetary gears. To spot spider gears look for the gears with the cross-pin shaft going through them.
