The Revenge kingpin is a fully solid, top mounting pin. That means it is not hollow in the middle, making it slightly heavier than the Reactor kingpin. The two pins are fully interchangable, the Revenge pin offers more strength. Because the pin is screwed directly into the plate, you do not need to order a mounting kit unless you want to remount your plates.
Sold as a Pair of 2
Please be aware that these kingpins have been known to loosen themselves at the base, so if you have them, keep an eye on them and check them at each training.
