UR Crank pulleys suck to get onto the car, but they really do make a difference!
They add power all across the rev range, they give you better acceleration

2. On some pullies there is a built in harmonic balancer. This is a well balanced mass with some insulation, that keeps the crankshaft stable from harmful vibration by absorbing it. If you're removing this type of crank pulley, you're going to see a shorter engine life. The vibrations damage the crankshaft and eventually your crankshaft will get cracked. These vibrations put a great deal of stress on your bottom end.

I was thinking of gettin them but I just keep hearing people say cons about crank pulleys. I heard something about if you have subs in your car, (crank pullyes) they dont produce enough power to handle the power being required by your subs. I dont know if this is bs or they were right.

Well thats bad news cause i have subs but i don't see how a lighter pulley wouldn't create even power to electrically power subs. Cause its light it spins up faster so you would think your subs would get more power?

it works just fine with a stereo system....I've got a very power hungry amp, and had no issues with the pulley
now you guys see though why we have not offered a presale...because the dates are always subject to change. Why? Because that's how manufacturing is, especially when you're doing it on a relatively small scale.
We ordered these for stock before anyone knew they were even coming available....when we have em, we'll post, but only when they are in our hands

at 4 pm on a friday on the summer, not unheard of....not that calling them is going to get them produced any quicker. They'll be done when they're done, not really anything anyone can do about it

What I wrote referred to what other people have to say about them in regards to engine longevity.
Besides these pulleys are stock diameter, they're not underdrive. They're just lightened billet pulleys.
