Moose Offroad Universal 520 FB Drive Chain
Moose Offroad Universal 520 FB Drive Chain is a high‑strength, sealed O‑ring drive chain designed for heavy‑duty use on a wide range of 520‑pitch applications, including ATVs, UTVs, and dirt bikes. It’s built using Moose’s “FB” (Fine Blanking) process for laser‑accurate links and stronger alloy steel, making it one of the toughest sealed chains in their lineup.
The 520 FB chain comes in multiple link counts (e.g., 100, 110, 112, 116 links) so you can size it to fit many 520‑pitch drivetrains, which is why it’s often marketed as a “universal” drive chain for off‑road and utility vehicles. It uses a narrow, high‑tensile 520 pitch with O‑rings to keep dirt and moisture out of the pins and bushings, while still delivering high tensile strength (around 35.3 kN or roughly 8,000 lb breaking strength depending on specific part number).
Features
- 520 pitch sealed O‑ring drive chain for universal fitment on 520‑sprocket applications.
- Fine Blanking (FB) manufacturing for precisely cut, stronger alloy‑steel links and superior durability.
- Sealed O‑rings help retain internal lubrication and resist contamination from dirt, mud, and water.
- High tensile strength (roughly 35.3 kN / ~8,000 lb), among the highest in Moose’s sealed‑chain offering.
- Available in multiple link lengths (for example, 100, 110, 112, 116 links) for different vehicle setups.
- Typically supplied with a clip‑type master link ready for field installation.
- Recommended for applications 450cc and above
- Tight tolerances make the plate, pin, and bushing union accurate and strong
- Special sealing rings are chemically treated to gain strength and reduce friction
- Replacement connecting link available
