Opinions on underdrive crank pulleys for a 4.0/auto? Someone mentioned that they've heard alot of issues with them for these cars. I've never seen an opinion one way or another before as to whether there are issues with them, or if their worth it for us.

 

Well the crank pulley is something I don't know to much about, but I did go with the Alt pulley from Pauls high preformance. It works well and I haven't had problems with it.
Good luck
