I have their serpentine setup. I’m pleased with the quality. They (CVF) are easy to work with as I changed the adjustment turnbuckle lengths and positioning on the A/C compressor and alt and they sent me what I needed along with extra belts to find what I needed.
Using the V-Belt pulleys for Alt, Crank, and Water Pump. Quality is very good and I found alignment best when using all of their pulleys (not a mix with 'stock').
I use the alternator water pump and main pulley as well with their alternator bracket. Love it.. had to shim out my water pump just a little bit..
Customer service was good they were willing to send me another one if I couldn't get it to work...
Did a full serpentine set up on a 65 GTO with AC power steering and the works and it is really nice...
Plan on getting the full set up for my truck...
I am. Good quality. I wish the black was available when I bought mine. I design and see a lot of machined aluminum parts and they were pretty good. I used stock pulleys with mine except the PS, that was a Tuff Stuff.
I am setting up their serpentine belt system right now. My set up is a little different since I am using as 215 amp PowerMaster alternator which required a GM pulley. Also using their power steering pump, and tried to use their water pump. The water pump had multiple issues, so switched it out to a Milodon. With the exception of the water pump, good quality parts, great customer service.
