The Wright Tool 3908 is a 12-inch 3/8-inch drive impact extension with black industrial finish, engineered to transmit pneumatic impact torque to deep fasteners.
Wright Tool has manufactured impact extensions in Barberton, Ohio since 1927 from U.S. steel. The impact-rated alloy absorbs the cyclic stress that cracks standard hand-drive extensions.
Use the 3908 for valve cover bolts behind air boxes, deep-set transmission fasteners, and any spot where the socket needs to reach a fastener far from the impact wrench. Lifetime warranty included.
