( Brand: Speedway Motors ), ( Part Type: Spring Tube Axle Spindle Motor ), ( Manufacturer Part Number: 91339008 )
The Speedway Motors 91339008 Spring-Behind Tube Axle Front End is a top-tier suspension component designed for Ford spindles. This axle assembly incorporates a spring-behind design, which moves the suspension springs behind the axle tube, resulting in improved weight distribution and enhanced handling capabilities.
The tube axle is crafted from heavy-duty steel tubing, ensuring robustness and durability under even the most demanding racing conditions. The high-strength steel used in the construction of the axle tubes guarantees excellent rigidity and resists flex, allowing for precise steering and optimized tire traction.
This front end axle system from Speedway Motors is designed to work seamlessly with Ford spindles, making it an ideal choice for restoring vintage Ford vehicles or building high-performance hot rods. Each axle tube comes with CNC-machined bushings for accurate alignment and long-lasting performance. The precision-engineered bushing design also minimizes unwanted play or vibration, ensuring excellent tire contact for maximum grip.
Additionally, the 91339008 Tube Axle Front End comes with a lateral bar that bolts to the chassis, creating a more stable and rigid suspension system. The lateral bar helps distribute the forces generated during cornering more evenly, reducing body roll and improving overall handling.
In summary, the Spring-Behind Tube Axle Front End 9133908 from Speedway Motors offers a robust, high-performance suspension solution tailored specifically for Ford spindles. With its heavy-duty tubing construction and spring-behind design, this axle assembly delivers improved weight distribution, enhanced handling, and precise steering capabilities, making it a must-have upgrade for any enthusiast or racer wanting to maximize the performance of their Ford vehicle.

Pros:1. Improved performance: The spring-behind tube axle design provides better weight distribution and improves the overall handling and performance of the vehicle.
