Who sells larger Alt pulleys?

[LowBuckX]

At 6000 rpm my Alt is dropping voltage

What i mean is when Im winding out going down the road at about 6000rpm my lights go dim till I shift. I put in a new 140 Amp powermaster cs-130 Alt.

Who sells larger alt pulleys to slow it down a bit. (Morosos 5" is to large)

Im thinking 3"-3.5" should be perfect

Are you sure you're ignition or something else isn't dragging it down? I've had a few CS-130's, and they've never dropped out like that.

If you're still sure- Billet Specialties, CV products, BLP, Moroso all make larger pullies. I personally like the CV stuff- you can get it in many sizes.

MY Old 64 amper didnt do this with the 6Al Ive been running for years. So I would have to say no on the ign pulling it down.
