520 FB O-RING CHAIN
- This is the top of the line – the strongest, most-durable sealed chain Moose Racing offers
- FB = Fine Blanking, an incredibly precise manufacturing process that yields perfectly cut links
- Tight tolerances make the plate, pin, and bushing union accurate and strong
- Due to the accuracy of the cuts and the use of 20% stronger steel, the FB has Moose Racing’s highest tensile strength rating, nearly 8,000 lb.
- The FB uses special O-rings which are chemically treated to gain strength and reduce friction; this treatment allows the FB-rings to be impregnated with grease
- FB-rings are more durable than X-rings, with significantly less friction
- Gold links and rollers, silver inner plates, pins and bushings
