Want the best for your equipment? Ever witness a lift chain break while driving down the road at 55 mph? Plows are heavy, they get heavier with options like thicker cutting edges, snow deflector flap kits, etc. The chain also sees much more abuse than just the weight of the plow while stacking heavy wet snow, especially when your 10,000 pound truck comes to a complete stop when you hit that snowbank while stacking. Also, the chain links are constantly wearing on each other as well as at the u-bolts not to mention the variable of corrosion. This is 20% stronger grade chain with grade 8 U-bolts. Better/stronger parts than Fisher factory at a lower cost. That's a classic win/win. The chain and Ubolts are gold chromate/yellow zinc plated. Fits XLS RD HD HD2 HDX XBlade snowplows. Replaces 26999-1 chain and A6148K U-Bolt (x2)
