I bought a valair clutch off ebay, and I have only good things to say about it. Not only is the clutch excellent, they have great customer service. I would recommend these clutches to anyone, and yes they are inexpensive compared to other brands out there. I have a 98 12v, #10 plate slid forward, 3000 GSK. After I got my clutch, my brother got one as well for his 99 24v, edge chip, and injectors, and he as as happy as I am. We pull gooseneck trailers occasionally and we are in a local truck pulling circuit. These clutches are holding great! Check them out at
