This shot shows how easy the Lock-In tool makes the job of installing each wristpin lock. Simply push against the wristpin and twist the tool clockwise to manually feed the lock into the piston groove. It really is that simple. Available for a variety of sizes, the Lock-In-Tool comes in either steel or plastic and is a must-have time-saver for anyone building engines. Prices are $120 for steel, $30 for plastic.
