Product Description

The KYB 565091 MonoMax Rear Shock is a heavy-duty performance replacement designed to dramatically improve rear suspension control and handling for Ford Super Duty trucks. Its gas-charged monotube construction delivers consistent damping performance, especially when towing, hauling, or driving on uneven terrain - offering up to 40 % more damping performance compared to standard twin-tube shocks.

Constructed with a durable zinc-coated piston ring and robust monotube body, this shock helps maintain steering and stability under load for 1999-2016 F-250 Super Duty and 1999-2007 F-350 Super Duty models with conventional rear suspension and without off-road package. It fits directly into OE mounting points with eyelet mounts at both ends, making installation straightforward and ideal for restoring original performance or upgrading your truck's rear ride quality.
