Different types of seals for different applications maximises efficiency and performance

O ring and RX Rings came first. Each a great product in their own right and broadly similar to the competition's current offerings

After several years of development, RK added the XW range of sealed chains to radically improve chain life and performance

As racing expanded into several different genres, RK also added the ultra thin U-Ring and UW-Ring sealed chains

Each seal type is specifically designed for a particular use to provide the ultimate in rotating efficiency with minimum friction, while providing a longer chain life

EXW is specifically designed for ATV/Off-Road vehicles and is the best high-speed, extreme heat, off-road performance chain available
