what clutch are you planing on? do you plan on doing more? what do you use the truck for? if you let us know that we can answer your question and recommend the best clutch for now and future mods....
It all depends on how much power you want to make. If you want 400 HP don't do a dual disc. If you want 500 you should probably start looking for a dual. If you want over 5 you need a dual. But if you are staying in the 400-425 HP range there is no need for a dual. A single will hold up just fine:thumbsup:
