I will soon be installing my Crower cams, retainers, springs, cam gears etc. along with new timing, balancer shaft belts and cam seals.

Is the AEM Tru Power underdrive pulley kit a worthwhile upgrade, as I could do this at the same time as my cams. Just like opinions from anyone who has them on already, do they make a difference and is it worth doing bearing in mind the cost of them.

Cheers,

Firthy

 

I have them, and am happy with them. only thing is at idle my headlights dim a bit. no biggie
