We tested the PullzAll in a whole assortment of different applications. The toughest test we performed was hoisting this front Dynatrac Prorock 60 front axle assembly up high enough so that it could be loaded into the bed of a Nissan Titan pickup. The 7/32-inch steel wire rope had no problem lifting the axle and the dynamic clutch prevented the load from creeping down after we released the trigger. The PullzAll didn't even seem as if it was working very hard during this test. We suspect Warn built in a considerable margin of safety when they rated the unit with a 1,000-pound capacity.
