I got the pulley bolt off pretty easy with a breaker bar and thought that I was in the clear. The damn lower pulley did not want to come off. I broke two 3 tooth pullers, probably because i got my puller from Harbor Freight for cheap. The Steeda pulley went on pretty easily. Everything is all back together and I'll be taking her out tonight to see if i notice a difference.

I have a set of Saleen pullies ready to go on my car. Let me know if you notice anything with the butt dyno

Is there any benefit in installing Steeda UDPs on a 4.0? I've seen that some people have done it but I'm not sure if it's worth the effort/$270

I did it because I got them for a good deal (about $130). I don't think I would have gotten them for full price. Notice a little gain, nothing major. I don't know anything about the 4.0. I'm sure it's not worth $270.

Did you have any issues with sealing the crank pully? I hear it can leak if its not done correctly

i didnt notice any power gains with my udp's but i did notice better gas mileage once i learned to let off the throttle

What difference is seen on the 4.6's?
