Calculating ring and pinion ratio // Winters Quick Change Tech

Many of our 10-inch racing quick changes use either a 4.12 or 4.86 ring & pinion ratio. In this video we explain how to quickly determine which ring & pinion you have by simply spinning your wheel or hub and counting the pinion rotations.

Since 1958, Winters has been crafting the highest quality performance rear ends and driveline components for racers and hot rodders alike. If we can answer any questions or if you’d like to view our online catalogs or request a printed copy, here’s how you can reach us:

So a lttle over 4 is 412 and a little under 5 is 486 ? Seems like the same thing 🤔
