EK O-RING CHAIN
EK's exclusive Quadra-X Ring seal gives their chains at least 50% longer service life and dramatically reduces friction.
Sideplate holes reduce weight, inhibit friction, dissipate heat, extend seal life, and facilitate self-cleaning.
Features include solid bushings, solid rollers and high-tech heat-treated steel alloys.
Complete installation instructions are included.
