Considering building a second "drag" diff. Have an event coming up where a 3.9 ratio may no longer be desirable. Considering my options and would love to hear what some of you have for sale. On ebay I can see that a full spool 31 spline centre and 31 spline axles will cost me about 1.1k Jack [phone removed]

el hefe do you think you'd be able to get away with a 25 spline minispool'd 308 or 345 for the wars of race or are you dead set on 28++?

Not so sure how that would take to 480 or more* horses. * may change fuels

I've got a full housing and axle 28 spline 3.45 minispooled diff doing nothing at all was going to keep it as a sparey but I will eventually be running a harrop trutrac in my barge
