But before choosing a kit, it’s important to understand why suspension upgrades matter and which OME system is right for your vehicle.
Why Upgrade Your Vehicle’s Suspension?
Factory suspension is designed for general driving conditions. Once you start adding modifications like bumpers, rooftop tents, campers, recovery gear, or larger tires, the stock suspension quickly reaches its limits.
A properly engineered suspension upgrade can provide several major benefits:
Improved Load Carrying
Overland vehicles often carry hundreds of pounds of additional weight from accessories and gear. Upgraded springs and shocks are designed to support these loads without sacrificing performance.
Better Ride Quality
High-quality shock absorbers reduce harsh impacts, improve damping control, and create a smoother ride both on pavement and rough terrain.
Increased Off-Road Capability
Suspension systems with increased travel and better damping allow your vehicle to handle rough trails, washboard roads, and obstacles with more control.
Proper Alignment and Geometry
When lifting a vehicle, components like Upper Control Arms (UCAs) help restore suspension geometry and alignment, improving steering feel and long-term reliability.
This is why suspension upgrades are often considered the foundation of a capable overland build.
Old Man Emu Suspension Systems Explained
Old Man Emu offers several suspension options designed for different driving styles and vehicle setups. The three primary systems most customers consider are Nitrocharger, MT64, and BP-51.
Each system offers a different balance of performance, comfort, and adjustability.
Nitrocharger: Reliable and Proven
The Nitrocharger suspension system is the most accessible entry point into the Old Man Emu lineup.
These shocks use a twin-tube design and are engineered as a durable upgrade over factory suspension. They are ideal for drivers who want improved ride quality and reliability without needing adjustable features.
Best for:
-
Daily drivers
-
Light overland builds
-
Moderate off-road use
-
Drivers looking for a dependable “set it and forget it” suspension
For many vehicles, Nitrocharger kits provide a noticeable improvement in comfort and control compared to factory suspension.
MT64: The Overlanding Sweet Spot
For many overland builds, the MT64 suspension system is the ideal balance between performance and comfort.
The MT64 uses a monotube design with a large 64mm piston, which increases oil volume and improves heat dissipation for consistent damping over long distances.
This makes it especially well suited for vehicles that travel long distances over rough terrain.
Additional features include:
-
Large oil capacity for improved damping consistency
-
Hydraulic end-zone rebound stop for smoother ride transitions
-
Durable aluminum construction for heat management
-
Designed for vehicles carrying additional gear or accessories
Because it blends the reliability of Nitrocharger with technology from the premium BP-51 system, the MT64 is often considered the best all-around suspension for overlanding.
BP-51: Maximum Performance and Adjustability
At the top of the lineup is the BP-51 suspension system, designed for enthusiasts who want ultimate control and adjustability.
These shocks feature internal bypass technology and allow drivers to independently adjust both compression and rebound damping to fine-tune performance for different terrain and loads.
The BP-51 system also features:
-
Position-sensitive damping for improved control
-
External adjusters for on-vehicle tuning
-
High-performance aluminum shock bodies
-
Exceptional performance in high-speed off-road conditions
Best for:
-
Fully built overland vehicles
-
High-speed off-road driving
-
Vehicles carrying heavy loads or campers
-
Drivers who want adjustable suspension tuning
