I am currently looking at purchasing a used 4.11 final drive. I was wondering if there is a way I can verify that it is in fact a 4.11 final drive just buy looking at it?

 

count the teeth. Divide the big number by the little number, and it should equal 4.11...

 

im confused at what you are saying. There are three sections the top smaller section has 19 teeth per set, the middle is slightly thicker and has 22 teeth, and the lower thicker portion has 18.

 

Here is an image of what I am referring too.

 

That is only part of the final drive set up, there should be a big cog that goes with it which isn't pictured.

You divide the number of teeth on the big cog by the 18 teeth in your pic.

 

He doesn't have the center ring that goes with it. I'm going to have to order that from Jack's but I wanna verify it is a 4.11 before I buy it and get the center ring.

 

Technically the item in the pic is the output shaft and the center ring as you call it is the final drive gear.

Sorry I can't help identifying if that shaft will match Jacks final drive gear

Hope someone can for you!

 

The teeth are at the bottom, the "18". The rest are splines...

 

stock 4.54 has 17 teeth
