Introducing the new Version 3 MPx Underdrive Pulley for the 03-05 Neon SRT-4 & 01-10 PT Cruiser. This pulley is yet another redesign of the famous MPx pulley that has been out for the since 2003.

This underdrive pulley creates more power over the stock pulley by reducing overall weight, and size of the crank pulley. This allows your car to rev faster, and overall be much more peppy.

We provide installation instructions, as well as new belts (option) for your power steering/ac, and alternator, so its a complete installation package! You need nothing else to install this other than your tools! (PS/AC belt 5040525, Alt 5040315)

Dustin H that owns a 2005 PT Cruiser 2.4 non turbo told us that he is using this pulley with AC delete kit and he is using belt number K040490 for the ps/AC belt.
