Remember that time you spent hours tweaking your differential, only to tear it down again because the contact pattern was off? We've all been there—chasing the perfect mesh between ring and pinion gears. That's where Richmond Gear 5500011 Marking Compound comes in. This trusty blue paste is your eyes inside the gear case, showing exactly where the teeth are hitting.
Without a marking compound, verifying pinion depth and backlash feels like working blind. Too shallow, and you'll get edge loading that chews up teeth fast. Too deep, and center contact leads to whining under load. Backlash that's off means binding or excessive play, shortening gear life. Mechanics and builders waste time and parts guessing instead of measuring.
Slap a thin layer on your ring gear, assemble, and rotate the pinion. The compound transfers a precise pattern revealing heel, toe, or face contact issues. Adjust depth with shims, dial in backlash with side bearings, and recheck—it's that simple. The formula's long life means it doesn't wipe off easily, giving consistent results over repeated trials until you're dialed in.
You'll save hours on each setup, avoid comebacks from noisy diffs, and build confidence knowing your gears will handle torque. It's not just for pros—weekend warriors setting up Ford 9"s or GM 10-bolts swear by it. The non-drying paste cleans up with solvent, no residue mucking up your fresh oil.
Whether you're freshening a daily driver rear end, building a drag strip terror, or restoring a classic, this compound ensures silence and strength. Pair it with a dial indicator for ultimate precision. One jar pays for itself the first time it prevents a $500 gear set mistake.
Grab the Richmond Gear 5500011 and make gear marking your new best friend. Your diffs will thank you with miles of quiet power.
