Key Features

The Fabtech Uniball Upper Control Arm System offers several advanced features designed to optimize your truck's suspension capabilities:

• Heavy-duty uniball joints provide superior strength and durability compared to standard ball joints, reducing wear and increasing longevity under off-road and heavy load conditions.
• Precision-engineered control arms are constructed from high-strength steel and feature a durable finish to resist corrosion and impacts.
• Designed for a 3.5-inch lift, this system maintains proper suspension geometry, ensuring optimal alignment and tire wear.
• DLSS (Dual-Rate Load Support) shocks are included, offering excellent damping performance for both on-road comfort and off-road control.
• Improved caster and camber angles help maintain proper steering response and handling characteristics.
• Made in the United States, ensuring quality craftsmanship and reliable performance.
• Compatible with factory mounting points, making installation straightforward without the need for extensive modifications.
• Supports increased wheel travel and articulation, enhancing off-road capability and ride comfort.
• Designed to withstand harsh conditions, providing long-lasting performance for demanding applications.

Construction & Design

The control arms are constructed from high-strength steel with a precision CAD-designed geometry to ensure perfect fitment and optimal suspension performance. The uniball joints feature a robust design that allows for greater articulation and reduces binding, which is essential for off-road driving and heavy-duty use. The durable finish on the control arms protects against corrosion and environmental damage, extending the lifespan of the suspension components.

The DLSS shocks are engineered with high-quality materials and feature a twin-tube design that offers consistent damping and improved heat dissipation. This combination of components results in a suspension system that is both resilient and responsive, capable of handling tough terrains and heavy loads with confidence.

Performance & Sound

This suspension upgrade significantly enhances your truck's handling, stability, and off-road capability. The increased lift provides better ground clearance, allowing you to navigate rough terrain more effectively. The uniball joints contribute to more precise steering and reduced deflection, translating into improved control and confidence behind the wheel. The DLSS shocks deliver smooth damping, minimizing body roll and ensuring a comfortable ride whether on highways or trails.

While primarily focused on performance and durability, this system also contributes to a more aggressive stance and improved overall vehicle appearance. The upgraded suspension components help support your vehicle's ability to handle demanding tasks while maintaining a comfortable and controlled ride quality.
