8.8 Rear

[Ghostrider59]

Picked up an 8.8,was advertised as a 3.73,but checking the tag it is a 3.08. Should I go with this ratio or change it to a 3.55 or 3.73? Motor is a 351 Windsor.

Take the differential cover off and verify what gears are in there. It will be stamped on the ring gear.

Thanks for the reply.I'm going to take cover off tomorrow to see what's in there. I don't plan a lot of hiway driving will 3.73 be ok ?

Yeah 373 are good all around gears

That stamp may just indicate what it had stock. Doesn't mean it wasn't changed to 3:73 at some point.

Personally I would get a rebuild kit and change out the gears and bearings and so on and so forth; peace of mind if you will. Leaky seals are no fun.

I had 3.73 gears in my last mustang. They are perfect in my opinion.
