8.8 Real resistance Difference 28 vs 31 splines

[patov6]

Well, I would like to know the real resistance difference between the F88 with 28 and 31 splines. I have now a 28 splines and running 36" with no issues (5.13, C-Clip eliminator, No Slip), and a friend of mine want to buy it, but he has the alternative of buy a 31 splines but no so complete.
What do you recommend?
Thanks in advance,
Pato

Do you mean the strength difference? (torque handling)?

Its somewhere around 35% stronger for the 31 spline.

Yep Junkie...thanks, and max tire size for each one?;)

Depends somewhat on the weight of the vehicle, but a general safe bet is:

37-39" for the 31 spline
33-35" for the 28.

I'd say the weak part of any 8.8 ... be it 28 or 31 spline is the carrier. Upgrade to a full carrier locker like a detroit or ARB and the strength goes way up.

Thumper (Warrlord) was running a 28 spline 8.8 with a detroit (and yukon shafts) with 37's at one time.

Well, I`m running 36 Iroks...with no issues...
