The underdrive pulley is also lightweight. Being that they are cut out of billet aluminum they are significantly lighter than the OEM steel pulley. It's technically a Lightweight Standard Sized

It's technically a Lightweight Standard Sized Crank Pulley vs. a Lightweight Underdrive Sized Crank Pulley |

Yes.. one or the other.
The standard pulley uses the stock sized belt.. the underdrive pulley uses a slightly smaller belt (because the pulley itself is smaller, and requires a belt that's shorter) As it's been discussed, the standard sized is for supercharged applications, as underdriving the supercharger would spin it slower and reduce the horsepower gain |

If you're planning on the STILLEN supercharger, you would need to use the Standard Pulley during that time. We have a lot of guys running the underdrive until the supercharger is available, and they will swap then.

I've only heard 1 person out of the hundreds that have purchased mentioned the steering at a dead stop seemed to take a little more effort, but that feeling was gone after a couple of days (getting used to it)..
Most others report no change is felt at all. |

Yeah I haven't felt any hugely noticeable change. I've had no issues with my steering or anything else since putting the UD pulley in.

No. My voltage meter hasn't dipped below 14 either, which is where it was prior to the installation. I don't think there will be any adverse effects until and unless you install some monster stereo system or something.

Okay, look, there are no negative effects to anything, period. None. Zero. Nada. Clear?
