The Old Man Emu MT64 rear heavy-duty shock, part arbMT64601010, is engineered for Toyota 4Runner and FJ Cruiser applications carrying increased overland equipment and accessories. It is designed to manage the added weight and shifting loads created by campers, toppers, tents, and rack systems while delivering vehicle-specific damping for different load conditions and vehicle setups. The result is controlled performance, improved comfort, and dependable handling on pavement, trails, and long-distance travel.
The MT64 uses an aerospace-grade aluminum body that dissipates heat significantly faster than steel while improving protection against stone damage. Its monotube design features a large 2.8-inch body for increased oil capacity and more precise shock tuning. Digressive valving responds immediately to changing surface conditions, helping the suspension maintain control as terrain and vehicle loading change. Forged body caps and rod ends reduce weight without compromising strength, making this shock well suited to demanding overland use.
An adjustable spring seat with multiple snap-ring grooves provides application-specific lift adjustment from 0 to 3 inches when paired with compatible coil springs. This flexibility supports stock or aftermarket lift-kit configurations while allowing the suspension to be tuned for the vehicle’s intended load. Vehicle-specific valving promotes a smooth, controlled ride for everyday driving and extended journeys, helping reduce fatigue and improve comfort for both driver and passengers. The Old Man Emu MT64 is a direct replacement for compatible stock or lifted suspension systems and is built for repeated on-road and off-road use.
