Renthal R3 Chain Renthal R3-3 chains are specially developed utilising Renthal’s SRS technology to increase the service life. The special SRS is pre-loaded during assembly, creating a spring effect. As a chain wears, conventional O-rings and X-rings loosen their seal whereas the SRS has the inherent ability to regulate a constant sealing pressure against the side plates throughout the life of the chain. This offers increased longevity, as the specially formulated grease remains encapsulated around the critical pin and bushing area longer whilst preventing ingress of dirt, water and other contaminants. Renthal R4 ATV SRS Chain A 520 SRS chain designed specifically for off-road, ATV, enduro and desert applications. The R4 ATV Off Road Chain has the following features: • Patented self regulating seals dramatically increase the life of the chain. • Larger diameter pins manufactured from specially enhanced steel improve the resistance to shock loads. • A quad riveting process on each pin increases the tensile strength of the chain. • Thicker inner and outer plates increase the fatigue life of the chain.

PROX MX Drive Chains PROX MX Chain Features:
• Exclusively manufactured for PROX by a reputable and leading OEM factory in Japan. • Pins feature an exclusive pin treatment providing an extremely hard outside coating, leaving a softer inside to increase strength while reducing overall chain wear. • Pins are heavy press fitted and feature quad staked riveting for ultra strong connection. • Solid type bush, roller and plates are all heat treated for incredible tensile strength in combination with low friction and high wear resistance. • Inner Plates are designed in specific shape and in combination with a unique lightening hole resulting in a 3% overall lighter chain. • X-Ring type chain uses QX-Type seal offering 40% less friction and at least 150% increased durability over standard MX chain. • All chains are pre-stressed and pre-stretched to reduce initial chain stretch and im- mediate performance. • Chains come with a clip type chain link as standard.
