| These torque extension bars are for use with 1/2-inch drive impact wrenches rated 380 to 420 foot-pounds of torque. Various torque limits allow use of any impact socket with a torque extension to match the different lug nut sizes found on vehicles.
The extension bars help prevent over-torquing of wheel nuts and minimize wheel distortion. The unique design allows the torque shaft length and diameter to flex with each impact wrench blow, once the specified torque is reached. Accurate to within 4 percent. Extensions are made of chrome vanadium steel and have color coded plastic sleeves. Includes plastic storage case. |
