At DMG Motorsports, we present the D.I.D Super 520NZR HD Rivet Master Link (ZJ520NZ) — the correct factory-style replacement connecting link engineered specifically for D.I.D's 520NZ Super Non-O-Ring chain. When it's time to install a new 520NZ chain or repair an existing one, this rivet-type master link restores your drive chain to its original strength and integrity, giving you a connection you can trust lap after lap or mile after mile. Backed by D.I.D's reputation for precision chain manufacturing, this master link is built to match the performance of every other link in your chain body, so there's no weak point in your drivetrain.

Features:

• Genuine D.I.D ZJ-type rivet master link designed exclusively for D.I.D 520NZ Super Non-O-Ring chains
• Hollow-tipped rivet-style pins that are peened/riveted for a permanent, factory-grade connection
• Delivers comparable strength to the other links in the factory-assembled chain, avoiding a weak link in the drive chain
• Recommended by D.I.D for endless (non-master-link) chain setups where a secure rivet connection is required
• Requires a chain press/rivet tool, such as the D.I.D KM500 series, for proper installation
• Natural finish, sold individually for easy replacement or chain assembly
• Ideal for street, off-road, and powersports applications running a D.I.D 520NZ chain
• Manufacturer part number 690-31002 / ZJ520NZ, ensuring exact fitment when matched to your existing 520NZ chain
