If I go from 3.4 to 3.2 or 3.1 shud I get a shorter belt. If I stay the same do I risk belt slap and throwing the belt? R/

 

I went from 3.4 to a 3.25 pulley and didnt have any belt slip or throwing.

 

I used a 111" belt on my 3.25 pulley, 110.5" on my 3" pulley

 

I went from a 3.4 to a 3.25 with no new belt and no problems.

 

Well...I did thro the belt...was jacking the truck trying to prompt a race and once I floored it the belt flew. Musta been slap as it wasn't damaged and I was able to put it back on after a scary moment or 2 with no steering!

 

That 3.73 Posi worth the effort?
