Calvert Racing adjustment wrenches make it easy to access adjustments on your CalTracs traction bar system. The wrenches have 1-1/8" opening for adjusting links and jamnuts. The 6" handle helps in low clearance applications where space is limited. Wrenches are constructed of heat treated 4340 chromoly for durability and longevity and finished in a gold plating to resist corrosion. Each package has 2 wrenches.
