Description
If you’re running a Renthal RR4 SRS 520 chain at the track, your master link is the critical connection point between power delivery and reliability. A worn or compromised master link introduces slack, misalignment, and catastrophic chain failure—exactly what you don’t need mid-race. The C378 rivet-type master link restores that security with Renthal’s proven SRS technology, ensuring your chain maintains consistent tension as miles accumulate.
This is a direct replacement for Renthal RR4 SRS 520 pitch chains, engineered to match the original specifications precisely. The preloaded SRS ring adapts to chain wear dynamically, keeping seal integrity tight throughout the part’s service life. Gold plating provides additional corrosion resistance, critical for extended storage or wet-weather conditions.
