DID Quick Lock Clip for 520 Chains (G&B520DZ2) — Locking Mechanism for Motorcycle Chain
Produkt: DID Quick Lock model G&B520DZ2 from DID. This quick lock (MPN: 748.98.42, GTIN: 4525516380942) is designed for 520-series chains and functions as the mechanical lock between the chain end links. It is used to connect chain extensions or join the chain after fitting the chain link on motorcycles, ATVs and similar vehicles where the 520 dimension is correct.
Funktion: The quick lock holds the chain plates together using a shaped clip, which is pressed or tapped into place over a squeeze hub/center pin. The locking mechanism is easy to install with common tools and is designed to ensure correct seating of the 520 chain link. It bears the axial load between inner and outer plates and provides mechanical fixation of the chain link during operation.
Materialer og egenskaber:
- Made of hardened steel with surface treatment, intended for wear resistance and corrosion resistance under normal operating conditions.
- The simple form and material choice focus on durability and precise fit to the 520 dimension, reducing the risk of lateral play in the assembly.
- The surface treatment provides basic rust protection; in aggressive environments, regular inspection and proper lubrication of the chain are recommended.
Kompatibilitet og anvendelse:
- Specifically designed for 520 chains — compatibility should be confirmed with respect to the chain manufacturer’s recommendations and chain link type (e.g., standard, reinforced, or O-ring/X-ring chains may have special requirements for the locking type).
- Suitable for mounting chains on motorcycles and small off-road vehicles where the 520 dimension is used.
- Not all 520 chains use the same locking type; follow the manufacturer’s instructions for the correct locking method (clip lock vs. retaining clip or press-fit couplings).
Technische Referenz und Identifikation: The product is marked by the manufacturer DID.

Ved montage og vedligehold:
- Ensure the quick lock sits correctly in the recesses on the chain plates and that it is fully seated over the center pin.
- After installation, briefly run the chain and re-check the lock for correct position and any movement.
- Use appropriate tools and follow the manufacturer’s assembly instructions to avoid damage to the lock and chain plates.
