AEM Tru Pulleys and UDP compatibility

[nelapse]

Without a doubt I will be getting a udp, but i was thinking about the tru pulleys from aem, are they even worth the 70 bucks? if so they are a bigger diameter so how will i find a belt to fit all the pulleys? thanks in advance

If you get a UDP, make sure it has a harmonic balancer. If you don't, the rotation of the engine will cause the crank bearings to wear unevenly and will cause premature engine failure.

that is only for the turbo engines, 420a cranks are internally balanced, and they do not make a harmonically balanced crank for us.
