ProTaper 520 Pro Series Forged Slim O-Ring Chain Link, Model 021697

Utilizing a newly developed manufacturing technique never-before seen in the off-road chain market, ProTaper Pro Series chains feature innovative forged pin collars that have been seamlessly incorporated into the outer chain plate. By cold-forging pin collars to encase the thermally refined alloy steel chromium carbide layered pins, outer chain plate thickness can be slimmed to reduce weight while increasing tensile strength. Featuring Slim O-Ring Technology, which offers superior, long lasting chain lubrication in a slimmer profile, eliminating the clearance issues of competing O-ring chain designs. The result is slim, ultra-premium, light weight racing chains with unparalleled strength and prolonged lubrication over the competition.

• Engineered for maximum strength, durability, and smooth power transfer in demanding off-road and racing conditions
• Built from premium materials with precision manufacturing to deliver long-lasting performance and reliability
• Lightweight design reduces friction and rotational mass for improved throttle response and acceleration

The ProTaper Pro Series Forged 520 Slim O-Ring Chain Link is designed for demanding off-road and racing conditions. It features forged pin collars seamlessly incorporated into the outer chain plate, helping provide a slim profile while supporting high tensile strength. Thermally refined alloy steel chromium carbide layered pins contribute to durability and reliable performance.

Slim O-Ring Technology helps retain chain lubrication in a narrower design, supporting smooth power transfer while helping reduce clearance concerns associated with competing O-ring chain designs. The lightweight construction is engineered to reduce friction and rotational mass for improved throttle response and acceleration. This product is identified by manufacturer part number 021697 and vendor part number 606347. Fitment is for applications requiring a 520-size slim O-ring chain link; verify vehicle and chain fitment before installation.
