FAQ

What is gear marking compound used for?
Gear marking compound is a specially colored paste applied to ring gear teeth to show the contact pattern with the pinion gear during setup. It helps you adjust the gears for optimal alignment and quiet operation.

How do I apply gear marking compound?
Apply a thin, even coat to several teeth on the ring gear, then rotate the axle through normal motion. Inspect the resulting pattern to check for proper contact between the ring and pinion gears.

Can I use gear marking compound with any differential or gearbox?
Yes! It’s suitable for all automotive differentials, manual gearboxes, and even some industrial gear applications—anywhere precise contact pattern checking is needed.

Is the compound easy to remove?
Absolutely. Our marking compound is formulated to wipe or wash off cleanly with a shop rag or light solvent once the setup process is complete.

Does it matter what color the compound is?
Not really—visibility is key. We offer compounds in bright, high-contrast colors like yellow or blue to show up clearly on both new and worn gears.

Will gear marking compound affect the performance or longevity of my gears?
No. It’s a non-abrasive, non-hardening compound made specifically for temporary use during gear setup.
