The Lisle 5-pc Thick Pickle Fork Set, No. 41220, provides extra lift when replacing worn out ball joints, pitman arms, pickup track bars and other applications. The forks are threaded to interchange with either the handle for hammering or the pneumatic driver (.401 shank) and a 6-1/4" extension that works with either handle to provide extra reach. The set includes five forks - 11/16", 15/16", 1-1/8", 1-7/16" and 1-5/8", which are heavy duty forgings. The handles are heat-treated alloy steel.
