FYI: UR Crank Pulleys have been discontinued.

[glitched]

Not only have the accessory pulleys been discontinued, but now the crank pulley has been discontinued as well.

I Noticed Jegs was having an awesome deal on Unorthodox Racing crank pulleys, however didnt have the KA model listed.

I called UR up and asked them for the part number and they said that they have just discontinued the crank pulley for the KA.

There is still a group buy to try and get UR to build another run of accessory pulleys:zerothread?id=332192

But now this sucks that they also stopped making the crank pulley.

I recently bought A UR crank pulley for my KA24E, I would say at least within two months ago. I put it on a couple of weeks ago, and haven't really had much problems. It does give a significant amount of power, I should think the 7-9 hp they claim is accurate. When I bought mine they were having a 50% off sale on my model so I got it for 80$.

If you do decide to get a underdrive pulley, I would suggest that you check and recheck all your grounds, terminals and connectors. Replace what you need to, and perhaps add some grounds. Yesterday, I did a **** load of driving, and after the fourth trip I made, my car wouldn't start, so I had to jump it. This may be my battery, but I will soon find out if my pulley's not charging my system correctly.
