Our Wearbars are made from the highest quality, cold roll, case-hardened steel used in the snowmobile industry. This gives you the best wear, least breakage, and greatest value for your money. Also, they are formed in a permanent jig to insure that they always fit equal to or better than original equipment. All studs or bolts are double welded for extra strength and then the Wearbars are painted black to resist rusting. Nuts are included.
