How to Measure Pinion Offset on any Rear End - 9", 8.8, 12 Bolt, 10 Bolt, Dana 60, 8 3/4

In this video, we talk pinion offsets. There are many offsets from the factory including center pinion, 3/16", 1/2", 15/16", 1 3/16", 2 3/16" and more. When in doubt, its time to get out the straight edge and tape measure. We walk you through how to measure drivers side F Dimension and passenger side G Dimension on the spec sheet. From here, we can calculate your axle measurements. Reach out if you have questions!

Great video!!
The more I read and watch videos, the more I get confused. Building a 37 Chevy Business Coupe...Engine Chevy SB & trans turbo 350 is down 3.55 degrees at the transmission. Rear end is 3.70 +/- .05 up. Am I good? I've been told no more than a 1degree difference.
Thanks

As far as the pinion angle goes, I'd recommend starting somewhere around 2-3 degrees down on the engine and transmission. The rear end should start out the opposite around 2-3 degrees up. They are opposite. You can always shim it a degree or two if you get any whine out of the pinion bearing. This is a general starting point. You can email me and I can send you some literature that is helpful from Inland Empire driveshafts. Have a good day @josephvolk7368

Great video, so have a 8.8 ford rear end that I cut 2 7/8 of an inch on one side to to make both axles the same length (shorter) ,tacked rear end centered in frame but noticed that it's offset and doesn't line up centered to my transmission does this mean that I won't be able to use this rear end or is there any solution to my encounter?😢

There is an offset built into the casting itself on an 8.8. What kind of vehicle is this going into? It sounds like you might've cut off more than you needed to depending what the original rear came out of. If the driveshaft itself is dead center on the rear, one axle shaft will be one inch longer than the short shaft. If you have an equal amount of tube sticking out the casting on each side you'd have a 1/2 offset with equal length axle shafts.

You need to go back to grade school and retake math. You just described a 53 1/4 inch rear end, not a 54 1/4 rear end. A half inch pinion offset to one side means the center line of the pinion is 1 inch closer to one side of the car than it is to the other. The Camaro pinion would measure 26 1/8 and 28 1/8. That adds up to 54 1/4.
