I thought you need a drive shaft loop to run any type of slicks

 

while not a neccesary part... i would get it just in case you happen to snap a driveshaft... a loose D/S can cause alot of damage.. ALOT OF DAMAGE!

A built rear is more what you want/need to use slicks on a regular basis

 

O i just thought it was a rule at tracks that if your running slicks you need a loop

 

And just curious did you ever get my pm cause it said it had a error after I replied.
