Tundra 2022-2026 Toyota Rear MT64 Shock (tuned for 440 to 880 lbs weight capacity) by Old Man Emu

Old Man Emu MT64 Rear Shock Absorber (Part Number MT64601032) for the 3rd Generation Toyota Tundra is engineered as a true all-around performance solution for overland-focused builds and heavily outfitted trucks. Designed to handle dynamic and constantly shifting rear loads, this MT64 shock is ideal for vehicles equipped with campers, toppers, roof tents, drawer systems, and rack setups that demand consistent control and comfort.

This rear shock is tuned explicitly for Tundras carrying 440–880 lbs of additional rear weight. It supports up to 2 inches of lift, making it an excellent choice for loaded overland configurations or work trucks running a constant payload. Vehicle-specific damping ensures the suspension remains composed and predictable whether driving pavement, washboard roads, or technical off-road terrain. At the core of the MT64 design is a massive 2.8-inch aluminum monotube shock body with an enormous 64mm internal bore. This increased oil capacity allows superior heat dissipation and consistent damping performance during long-distance travel and repeated off-road impacts. Digressive valving reacts instantly to changing surface conditions, delivering a smooth ride at cruising speeds while maintaining firm control when encountering large bumps or uneven terrain.

The shock body is constructed from aerospace-grade aluminum with a military-spec hard anodized finish, offering excellent resistance to corrosion, extreme temperatures, and stone damage. A large 22.5mm hard chrome piston rod provides exceptional strength and stability, while forged aluminum end caps reduce overall weight without sacrificing durability. Ride comfort is further enhanced by a hydraulic end-zone top-out design that adds cushioning at full extension, reducing harsh impacts and improving overall suspension refinement. Double-bonded rubber bushings improve noise, vibration, and harshness isolation, making the MT64 well-suited for long days behind the wheel.

Designed, engineered, and manufactured in-house by ARB’s Old Man Emu suspension team, the MT64 rear shock delivers proven overlanding performance with everyday drivability. This shock is a direct replacement for stock or aftermarket rear shocks and is backed by ARB’s global support network and a 3-year warranty, ensuring confidence mile after mile.
