D.I.D. FJ520ATV2 520ATV2 Press-Fit Clip-Type Connecting Link Gold & Black

The D.I.D. FJ520ATV2 is a press-fit clip-type connecting link (master link) designed exclusively for use with D.I.D.'s 520ATV2 X-Ring chain. Part of D.I.D.'s Exclusive Racing Series, this connecting link matches the performance and finish of the 520ATV2 chain with a striking gold and black color scheme.

The 520ATV2 chain series features D.I.D.'s patented X-Ring seal technology, engineered specifically for ATV and quad racing applications. The X-ring design reduces friction through a twisting action between the side plates rather than being compressed, which disperses pressure, minimizes power loss, and delivers superior sealing performance compared to standard O-ring chains. This results in half the power loss and up to 1.5–2x the wear resistance of conventional O-ring chains.

The link's steel alloy construction is specifically formulated to resist heat cracking caused by the extreme thermal cycling experienced during hard competition use. Thicker, reinforced side plates provide the extra strength demanded by quad racing while delivering a 7% weight saving, 10% strength increase, and 8% longer wear life.
