31 Spline diff questions

Im afraid this winter, its time to dump some money into the rear end considering i've got one wheel peel out the ass. I'm pretty sure im gonna get Superior 31 spline axles, an FRPP 31 spline diff, and 3.73 gears. Heres my question...is there a big difference between a 31 spline traclock diff out of an explorer or truck, and the FRPP unit? I've found them used on ebay and corral for $100 and under, and i's just wondering if its worth it, or if theres any better choices. This is somewhat of a budget build as i have to get a new radiator too, and i dont have a lotta cash, but i dont wana just rebuild the stock one because im gonna keep racing a lot. Thanks guys

I went with the 03 Cobra diff from John Bleakley Ford. I think they raised the price cause I don't remember spending near $240. But it's a good deal either way.

yea thats what i was planning on getting, but is that the same thing as the traclock in the explorers and trucks?

ok cool, thats what im gonna do then..i only have 200hp i dont need superness...i think ill be fine with an explorer diff and the superior axles
