1638 D.I.D X-RING® IS THE SUPREME LEADER IN HIGH PERFORMANCE CHAIN 1.5 to 2 times longer wear resistance (Compared with normal O-ring) The twisting resilience of the X-ring’s four sections greatly increases its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-ring. X-rings have the greatest wear resistance of any other type of O-ring or non-O-ring chain. VM SERIES GOLD 520ERT2 Adjusting your chain! SAG should achieve 3/4” See diagram A chain is only as strong as its weakest link! The ZJ connecting links are as strong as the rest of the chain thanks to the new rivet head design. 520MX D.I.D.’s patented X-ring construction reduces friction by twisting between the side plates instead of being squashed. Normal- O-rings and other makers modified O-rings have squashed points that increase friction. The twisting action of the X-ring disperses the pressure and minimizes power loss. 530ZVM2 520ATV Half the Power loss (Compare with normal O-ring) ZJ Link *Special ZJ Riveting Tool Necessary* 520ERV3 520ZVM2 & 525ZVM2 ER and NZ Series Exclusive Dai-Hard Process: Forms an extremely hard chromium carbide layer on the pins surface while maintaining a soft inner core. This provides extreme impact strength and superior wear resistance while maintaining wear resistance while maintaing outstanding shock absorption. Very well suited for motocross applications.
