Dana Gear/spool series question

FED 387 · 02-16-2013, 10:32 AM

If I remember right 3:54-4:10 uses one spool and 4:56-7:17 uses the other not sure just where a 4:30 would fit in tho---FED387

The 4.30 street gears go to the 3 series carrier, which is 4.10 and numerically lower ratios.
I have a customer who used to switch back and forth from 4.30's to 4.56's.
We machined the bearing shoulder on a 4 series spool and made a thick shim so we can use only one spool for both ratios.
Now Strange has a 4.30 Pro gear that fits the same spool as a 4.56

Thanks for the info,, Tom. I'm going to have to check into that for my own project.
