Hey guys i need some help figuring out what gear ratio is in my 88 bronco rear end. The sticker on the door has an axle code of 19. does this tell the ratio? i Know its a 8.8 just need to know the ratio
thanks for any help!

 

My manual shows that axel code 19 has a weight rating of 3800 lbs. and a 3.55 axle ratio.

And the differential is open.

 

Now that is a nugget my manual doesn't have. Perhaps you can answer a question about my axle. I have an F250 with axle code 65, which my table shows is a 4.10 ratio with a weight rating of 8250 lbs. Is it open or limited slip?

Thanks,
Scott

 

how about on my 1991 Ford F150 XLT Lariat 4x4,it shows a H9 as the axle code,any help!!

 

I've still got the page open. Axle H9 is 3.55 axle ratio with 3800 lb. weight rating. My table doesn't have anything about limited slip vs. open, though.

56 is an open the rest you are correct on according to my book

 

I take it "56" is just "65" transposed. If so, I thank you for confirming what I thought. Now I know that I really have to be careful about getting stuck in our slippery Willamette Valley clay soil.
