Our new-and-improved Clutch Pullers are heat-treated, hardened and then coated to prevent rust in order to exceed factory puller specs. This hardened and oxide-coated (oil impregnated) puller is more durable and reliable than other zinc-plated pullers, which can start flaking on the threads and cause all kinds of issues. Compatible with all Maverick X3 models, plus additional Maverick, Defender and Commander models.
