XTREME #35 chain by RLV is designed to be a premium racing go-kart chain. 

The chain is lighter, which equals less rolling resistance and faster acceleration. This increased acceleration is not at the expense of strength. The tinsel strength of the chain is more than 2,300 P.S.I. XTREME chain is pre-lubricated and pre-stretched, which reduces the need for adjustment. Xtreme chain is free rolling with less drag due to the unique spacing and clearance between bushing, pin, and sidebar. This is known as “space chain” The sidebars are plated to reduce the distribution of oxidized and corrosive particles that may become trapped between the bushing and the pin, causing kinking and premature chain failure. The Master link included Part Number 0845 for Gold on Gold.
