Renthal 520 R3-2 O-Ring Chain Natural Renthal's R3 O-ring chain is a high-strength, sealed-ring chain with excellent impact load resistance designed specifically to withstand the stress found in offroad applications. This chain is the choice where a combination of high-strength, lightweight and maximum power transfer are important considerations. The O-rings help extend chain life by retaining the special vacuum-injected grease near the critical pin area. Chain comes pre-stretched to shorten break in period. Nitrile O-rings help extend chain life. High-carbon alloy and shot-peened steel side plates for high-tensile strength and maximum impact load resistance. Chamfered inner links to help reduce the chance of chain derailment. Extended bushings to reduce friction between inner- and outer-link plates. Shot-peened solid rollers and chromized pins help to extend service life.

• Average tensile strength is 7,644 lbs.
• Gold-anodized side plates help prevent corrosion
• Every R3 chain comes pre-stretched for enhanced performance
• Each chain includes masterlink and a pair of latex gloves for mess-free installation
• Make sure to check your owner’s manual for the proper application, especially if installing an O-ring chain on a bike originally equipped with a non-O-ring chain
