RK 520 MXZ5 Gold Racing Chain, 116 Links (GB520MXZ5-116)

The RK GB520MXZ5-116 520 MXZ5 chain is engineered for high-performance off-road and racing applications. Its chromoly steel construction provides a strong, durable foundation, while seamless rollers and bushings support smooth operation under demanding conditions. The gold finish gives the chain a distinctive appearance while maintaining the performance-focused design expected from RK racing components.
Reinforced chromized pins significantly improve wear resistance compared with standard non-sealed chains, helping the chain withstand the repeated loads and harsh conditions associated with competition use. Every component is heat treated using RK’s exclusive Heat Induction Transfer process to enhance strength, durability, and long-term reliability. The chain includes 116 links for fitment flexibility across compatible applications.
The MXZ5 also features a less tacky grease formulation that is less likely to attract dirt and debris. This helps reduce contamination around the chain and supports cleaner operation during use. The RK GB520MXZ5-116 is designed specifically for racing and off-road environments and is not recommended for street use. Verify vehicle compatibility, chain size, link count, and required fitment before installation.
