The Old Man Emu MT64 rear shock, part number ARBMT64601009, is engineered for Toyota 4Runner and FJ Cruiser applications that carry the added weight of overland equipment. Campers, toppers, tents, racks, and other accessories can create shifting front-to-rear and side-to-side loads, requiring precise damping and durable construction. This vehicle-specific shock is tuned to provide a controlled, comfortable ride for daily driving, long-distance travel, and demanding off-road conditions.
The MT64 uses a monotube design with a large 2.8-inch body that increases oil capacity and supports accurate shock tuning. Its digressive valving responds immediately to changing terrain, helping maintain tire control and consistent performance across uneven surfaces. An aerospace-grade aluminum body dissipates heat up to 15 times faster than steel while helping protect the shock from stone damage. Forged body caps and rod ends reduce weight without compromising strength for extended overland use.
An adjustable spring seat provides application-specific height adjustment from 0 to 3 inches when paired with compatible coil springs. Multiple snap-ring grooves in the strut body allow the spring seat position to be changed for different vehicle setups and load requirements. The MT64 is designed as a direct replacement for stock shocks and compatible aftermarket lift kits, with damping calibrated for the intended vehicle and driving conditions. Fits select 2010–2012 Toyota 4Runner and 2010–2012 Toyota FJ Cruiser applications. Professional installation is recommended, and suspension compatibility should be verified before ordering.
