These chains offer the most extreme traction with welded case hardened studs. It is intended for use off-road in snow, ice, and mud. Chains come equipment with side cams. Cams allow for easy tensioning of chains.
Made to Canadian specifications, these chains do not conform to an SAE class as they are overbuilt, and components used are all oversized. Ensure vehicle has sufficient clearance to use these chains. Scorpion Studded chains offer the highest height profile off the tire, ride is very rough, but the case hardened studs on these chains dig into deep snow and grip the ice. These chains should only be used off-roads. The case hardened chain also makes this a good choice for mud service vehicles.
Typical uses would be for 4x4 for hunting & fishing. Industrial applications would be for use on logging roads, and for off-road oil-field or mining access.

These chains are fitted with 3 cams per tire for easier tensioning of chains. Simply install chain tight with cams in extended position, then close the cams as necessary to take up any residual slack. It is not neccessary to close all the cams. Just close cams to fit chains snuggly, but not so tight that chains exert pressure on the tire itself.
