Drag slicks or treads
 

Im looking for some drag slicks or treads (rear) for a new project i will be starting but they need to be big obviously and grippy. I don't know if xmods drag slicks are any good.

What is the most reliable diff when locked? (stock, gpm, ball)

... i would go for GPM... ball is more for good turning.. and when you lock it use crazey glue to lock it :-D it works great!

for the xmods slicks they are good and grip well

and has for the diff

they would all act the same if they are locked

but if you think about why would you pay $15-$20 for

a gpm or atomic diff if you could just lock the diff you have now

just looking for a stronger, more reliable diff. i will have gpm dogbones and open bearings for this too.
