At DMG Motorsports, we present the D.I.D Exclusive Racing 520ERV3 Rivet Master Link in Gold (ZJ520ERV3) — the factory-correct connecting link engineered specifically for the D.I.D 520ERV3 racing chain. As the world's leading chain manufacturer, D.I.D builds this rivet-style master link to match the strength and construction of every other link in the chain, so you never sacrifice reliability at the connection point. Whether you're closing out a fresh 520ERV3 chain install or carrying a spare for race day, this gold-finished link delivers the rigidity and durability that D.I.D's Exclusive Racing lineup is known for.

Features:

• Purpose-built rivet-type master link designed exclusively for the D.I.D 520ERV3 chain
• Greater rigidity than clip-type links, contributing to smoother handling, reduced power loss, and quicker throttle response
• Unique pin head designed to be precisely riveted in a uniform circular configuration for superior joint strength
• Comparable tensile strength to the other links that make up the factory-assembled chain body
• Gold-plated finish to match gold 520ERV3 chains for a clean, factory-correct look
• D.I.D recommends this rivet-type master link for chains originally equipped as endless (non-clip) chains
• Installation requires a proper chain press/rivet tool, such as the D.I.D KM500, for correct assembly
• Sold as an individual replacement link, ideal as a spare or for completing a new chain install
