The Dana 50 Twin Traction Beam (TTB) axle is a legend in the off-road world, renowned for its strength and durability. When combined with a long-travel suspension system, it becomes a truly formidable setup for serious off-road adventures. This article will explore the intricacies of Dana 50 TTB long-travel setups, addressing common questions and providing valuable insights for enthusiasts and builders alike.
What is a Dana 50 TTB Axle?
The Dana 50 TTB is a heavy-duty front axle originally designed for larger trucks and SUVs. Its defining characteristic is the "twin traction beam" design, where two parallel beams connect the axle housings, providing exceptional strength and rigidity. This design is particularly well-suited to applications requiring significant articulation, making it a popular choice for off-road vehicles. Compared to independent front suspensions, the TTB offers greater ground clearance and more robust axle strength, capable of handling extreme forces encountered during off-road driving. However, its solid axle design means less articulation than an IFS system in certain situations.
What Makes a Long-Travel Dana 50 TTB Different?
A "long-travel" setup refers to the suspension's ability to move up and down, significantly increasing wheel articulation. This is achieved through modifications to the suspension components, such as longer control arms, longer shocks, and sometimes modifications to the axle itself. A long-travel Dana 50 TTB drastically improves the vehicle's ability to navigate rough terrain by allowing the wheels to maintain contact with the ground even on uneven surfaces. This maximizes traction and improves stability, particularly at high speeds over challenging terrain. However, it's important to note that increased travel often compromises on-road handling.
What are the Benefits of a Long-Travel Dana 50 TTB?
- Increased Articulation: The most significant benefit is the improved wheel articulation, allowing for significantly better traction and stability over rough terrain.
- Improved Ground Clearance: The extended travel allows the axle to maintain higher ground clearance, reducing the risk of damage from obstacles.
- Enhanced Off-Road Capability: These improvements translate directly into significantly improved off-road performance, particularly in demanding conditions.
- Stronger Axle: The Dana 50 itself is already a remarkably strong axle, further enhanced by the robust nature of the long-travel setup.
What are the Drawbacks of a Long-Travel Dana 50 TTB?
- Increased Complexity: Long-travel setups are more complex than standard suspensions, requiring more specialized knowledge and parts.
- Higher Cost: The components for a long-travel system tend to be more expensive than those for a standard setup.
- On-Road Handling Compromises: Increased suspension travel often leads to less predictable handling on paved roads. Steering can feel vague and the ride can be harsher.
- Maintenance Requirements: The increased complexity and stress on the components mean higher maintenance demands.
How Much Does a Long-Travel Dana 50 TTB Cost?
The cost of a long-travel Dana 50 TTB setup varies significantly depending on the components used, the level of customization, and the labor involved. You could expect to spend anywhere from a few thousand dollars for a more basic setup to tens of thousands for a highly customized, high-performance system. Factor in the cost of installation and any additional modifications you might need, like custom driveshafts.
Where Can I Find a Dana 50 TTB Long Travel Kit?
Several companies specialize in manufacturing and supplying long-travel suspension kits for Dana 50 TTB axles. Researching different manufacturers and comparing their offerings will be crucial to finding a kit that matches your specific needs and budget.
What are the Different Types of Long-Travel Dana 50 TTB Kits?
Long-travel kits vary in design, utilizing different approaches to achieve increased suspension travel. Some focus on high-quality components, while others may prioritize affordability. The best kit for you will depend on your budget, intended use, and vehicle type. You'll likely find options categorized by travel length (e.g., 12-inch travel, 15-inch travel, etc.).
This article provides a general overview. Specific requirements and choices will depend heavily on your vehicle and its intended use. Remember to consult with experienced off-road mechanics and builders to ensure a safe and effective installation.
