Ive had the pulleys on since 98. Spring summer and fall it has been my daily driver up untill the last 2yrs. Since then, been more of a garage truck lol. Seem to work on it a lot more than I drive or race it now.

Be warned though, battery can take a beating with 3pc u/d pulleys. I am on my 3rd battery. The Optima seems to handle it much better than the other batteries Ive used in the past. Big stereo dont go more than 2pc pulleys.
