What do you guys think of the one sided Zpak 3-4 clutch packs.

 

they have shown to have very good results. i'm still in question as to if they have more holding power than the blue's in a race type situation. the z-pack is very good though in towing and heavy duty conditions. certainly is capable of taking power. the blue's can be set up well enough to break the input shaft even on the shift into 3rd which is a common slipping set (the 3-4 clutches).

 

imho (newbie to this site) i would go with zippy on the raybestos or even alto red eagle clutches, along with the superior billet goodies. might try the raybestos pro-series black kevlar band. i would also try the sonnax kit to keep those nasty 1-2 shifts problems from creeping up on you. again just my HO.
