I installed them, easy to do with simple tools and an easy and cheap 8-10HP

To Tell you the Truth I think most of the UD Pulleys are made by Steeda

These pulley kits only include the harmonic balancer and the water pump pulley, not the alternator pulley as in previous underdrive kits. The 2005 Mustang GT engine has a 1 way clutch built into the alternator pulley to prevent the inertia of the alternator stator from flipping the belt off on engine overrun. Less knowledgeable manufacturers will have you remove this pulley, then you wonder why you have belt durability problems.

Saleen makes a Kit with a Alternator Pulley
Note: A special tool is required for the alternator pulley replacement.

I have installed the Pulleys they are easy to install, also you do feel the performance right off the bat. STEEDA has great quality Performance Parts...
