The Dana 50 Twin Traction Beam (TTB) axle is a legend in the off-road world, known for its strength and durability. But when you're tackling serious terrain, even the robust Dana 50 can benefit from long-travel modifications. This comprehensive guide explores the intricacies of Dana 50 TTB long-travel setups, covering everything from the benefits and drawbacks to common modifications and considerations.
What is a Dana 50 TTB Long Travel Setup?
A Dana 50 TTB long-travel setup refers to modifications made to a Dana 50 Twin Traction Beam axle to significantly increase its suspension travel. Standard TTB suspensions have limited articulation, hindering performance on challenging trails. Long-travel modifications address this limitation, allowing the wheels to move up and down further, dramatically improving off-road capability. This increased articulation translates to better traction, smoother rides over rough terrain, and a more controlled driving experience at high speeds on uneven surfaces.
Why Choose a Dana 50 TTB Long Travel?
The Dana 50 TTB, even in its stock configuration, boasts impressive strength. Combining this inherent robustness with a long-travel suspension yields a potent combination for serious off-roading.
- Superior Strength: The Dana 50 is renowned for its ability to withstand immense stress and strain, making it ideal for heavy-duty applications.
- Increased Articulation: Long-travel modifications allow for greater wheel travel, improving traction and stability over obstacles.
- Improved Ride Quality: The increased suspension travel absorbs bumps and impacts more effectively, resulting in a smoother, more comfortable ride.
- Enhanced Ground Clearance: Increased suspension travel often translates to increased ground clearance, allowing you to tackle more challenging terrain.
What are the Drawbacks of Dana 50 TTB Long Travel?
While the benefits are considerable, it's crucial to acknowledge the potential downsides:
- Increased Complexity: Long-travel conversions involve significant modifications, often requiring specialized tools and expertise.
- Higher Cost: The parts and labor involved in a long-travel conversion can be expensive.
- Increased Unsprung Weight: Adding long-travel components increases the unsprung weight, which can impact handling and ride quality if not carefully managed.
- Potential for Increased Maintenance: More complex suspension systems can require more frequent maintenance.
What components are typically involved in a Dana 50 TTB long-travel conversion?
A typical long-travel Dana 50 TTB conversion involves several key components:
- Long-Travel Suspension Arms: These are crucial for increasing suspension travel. High-quality, durable arms are essential.
- High-Clearance Knuckles: These provide increased ground clearance and improve steering geometry.
- Longer Shocks and Springs: These are necessary to accommodate the increased suspension travel. Choosing the right shock valving is crucial for optimal performance.
- Steering Modifications: Adjustments to the steering linkage might be needed to maintain proper steering geometry.
How much does a Dana 50 TTB long-travel conversion cost?
The cost of a Dana 50 TTB long-travel conversion can vary greatly depending on the specific components used, the labor involved, and the level of customization. Expect to invest a substantial amount, potentially ranging from several thousand dollars to tens of thousands, depending on the complexity of the build.
What are the benefits of a Dana 60 over a Dana 50 TTB for long travel?
While the Dana 50 TTB is a strong axle, the Dana 60 offers even greater strength and capacity. The Dana 60 is generally preferred for extremely demanding off-road applications where the extra strength is necessary. However, Dana 60s are also heavier and more difficult to work with, making the Dana 50 a popular choice for those seeking a balance between strength and manageability.
This guide provides a foundational understanding of Dana 50 TTB long-travel setups. Remember to consult with experienced off-road professionals for advice tailored to your specific needs and vehicle. Always prioritize safety and thorough planning when undertaking such significant modifications.
