ARB Old Man Emu MT64 Suspension Kit – Toyota Tundra (2022+)
Medium & Heavy Load Configurations
Built for real-world overlanding, towing, and daily driving, the Old Man Emu MT64 Suspension System delivers controlled comfort under load without the complexity of external adjusters or reservoirs. Designed and engineered by ARB, the MT64 system is the go-to choice for drivers who want durability, consistency, and confidence across long distances and changing terrain.
MT64 takes its name from its massive 64 mm internal bore monotube design, allowing for increased oil volume, improved heat control, and vehicle-specific damping tuned for modern trucks carrying real weight. This system is ideal for Tundra owners running bumpers, canopies, campers, trailers, or constant rear loads, while still maintaining composed on-road manners.

Front ride height is fixed by the MT64 strut assembly. Rear ride height and load handling are determined by coil selection.

MT64 Suspension Technology
The MT64 system is designed for endurance. Unlike high-pressure nitrogen shocks, MT64 uses a low-pressure monotube design with a massive oil volume to reduce heat buildup and maintain consistent damping over long distances.
Key characteristics include:
-
64 mm internal bore for improved oil control and heat dissipation
-
Vehicle-specific valving tuned for the 2022+ Toyota Tundra
-
Fully sealed design for long service life with minimal maintenance

Smooth, predictable ride under varying loads
-
Engineered for daily driving, towing, and extended off-road travel
This is a suspension system built to perform day after day, not just on short trail runs.

Frequently Asked Questions
Is this suspension adjustable?
The MT64 system does not use external adjusters. Performance is achieved through ARB’s vehicle-specific valving and internal design rather than user tuning.
Is this suitable for daily driving?
Yes. MT64 is engineered to provide controlled comfort on pavement while remaining stable under load and on rough terrain.
Which rear coil should I choose?
Choose Medium Load if your truck is stock or lightly outfitted. Choose Heavy Load if you carry a constant rear load around 440 lb such as drawers, gear, or a fridge.
Do I need upper control arms?
They are strongly recommended to improve alignment and steering feel on lifted vehicles.
Is professional installation recommended?
Yes. Cap-it locations across Canada specialize in suspension installation, setup, and warranty support.
