JKS Manufacturing


JKS Manufacturing has just released a simple, yet brilliant tool for Jeep owner that is a must have for any tool kit, the compact jam nut wrenches for 1” and 1-1/4” jam nuts. Designed for use with jam nuts on JKS adjustable track bars, these wrenches can be used for any track bar, control arm, etc with standard 1” or 1-1/4” jam nuts.  Built from 3/8” laser cutting low carbon steel with a durable black e-coated finish, these wrenches are both unique and functional.  The design allows them to be used in multiple positions when coupled with a standard ½” drive ratchet. The ratchet can be indexed for the optimum position and leverage. The wrenches are designed to grab all 6 sides of the nut similar to a line wrench used for brake line fittings.  This provides a good no-slip grip on the nut for less chance of bloody knuckles.  Last, they are compact.  Standard opened end wrenches of comparable size are generally 4 times longer.  Standard wrenches are not only difficult to fit in the tight areas, but take up a ton more space in your tool box.  The JKS jam nut wrenches easily fit in the front pouch of a standard tool bag or the center console of your Jeep.
