The DID DHA hard pin kart chain is a stronger, more durable version of one of the most popular karting chains on the market. If you are looking for a heavier duty version of the DID 114L kart chain, then the DID DHA hard pin kart chain is for you. We are big proponents of DID chains at K1 Race Gear, and highly recommend the DID DHA hard pin kart chain for karters who require peak performance out of their chassis, engines and kart gear. The #219 gold-on-gold hard pin kart chain has a host of features that make it ideal for both amateur and professional karters, including: A coated boundary layer (hard chromium-carbide) on the pin to help absorb harmful abrasives and oxidizers and to extend the life of the chain A heat treatment that makes it up to 19 percent stronger than a non-treated gold-on-gold chain as well as more resistant to stretching Solid bushings with quad riveted pins for increased strength To learn more about the DID DHA hard pin kart chain, we invite you to contact K1 Race Gear today.
