OTC 4111 55-Ton Aluminum Single-Acting Spring-Return Ram, 6-1/8" Stroke.
Get the strength of a steel ram but with about half the weight. Can be easily carried around the garage, shop, or into the field for on-the-vehicle repairs. They are ideal for truck axle correction, trailer frame straightening, general vehicle maintenance, and heavy-duty lifting.
OTC's design ensures positive, leak-resistant sealing throughout all pressure ranges, yet full piston return characteristics are maintained. Additional bearing surface has been designed into these units to effectively resist the punishing stress exerted by off-center loads. Depending on capacity, this ram can handle a variety of bending and straightening jobs, construction maintenance applications, pressing operations, body and frame straightening, and rear housing and axle correction.
