Quality products, fast shipping. Streamlined core return process. Will definitely be a return customer and will recommend Riffraff diesel.

Called in and Clay veryfied stock right away for me and with in half hour everything was processed and done

The pistons look really nice high quality, no corners cut here.These folks are the greatest I can't say enough good about them. Clay goes out of his way to take care of his customers. Keep it up and Thanks Again, Art.

These are a good upgrade to the stock pistons in a 6.4. Just a not for those looking to use these, the rings(standard bore) are sized good right out of the box. It is a good idea to check them anyway, but you do not need to file these to Ford's quite loose spec on the second ring.

Clay is very nice to deal with. Product with as described. Coated pistons very nice though. Maybe next time Ill get shirt. lol

Best Pistons for the best price as usual when dealing with Clay. THANKS MAN
