Description
The 11405 is engineered to solve the problem of “bracket rotation” under the massive torque loads of a quick-change or Ford 9-inch rear end. By utilizing a “Keyed” design, this bracket interlocks with a corresponding keyway on the axle tube (or a keyed spacer), ensuring that your suspension mounting points stay perfectly synchronized. This is critical for maintaining consistent rear-steer characteristics and “bite” coming off the corners.
Detailed Technical Specifications
1. Heavy-Duty Steel Construction
-
Weldable Alloy: Precision-cut from high-grade steel that offers excellent weldability to both mild steel and chromoly axle tubes.
-
Massive Load Capacity: The thickness of the plate is optimized to resist “walling out” of the bolt holes, even when using high-horsepower engines and high-grip tires.
-
Burn-Through Resistance: Designed with enough material mass to handle professional-grade MIG or TIG welding without warping the bracket’s geometry.
2. The “Keyed” Precision Advantage
-
Index-Locking: The keyway slot allows the fabricator to lock the bracket into a specific degree of rotation on the axle tube. This eliminates the “measure twice, weld once” anxiety of standard round-bore brackets.
-
Synchronization: Ensures that the left and right trailing arm mounts are perfectly “timed,” which is essential for a car that tracks straight and responds predictably to tuning changes.
3. Suspension Geometry & Fitment
-
Multiple Mounting Holes: Typically features a vertical array of holes, allowing the racer to adjust the “instant center” and “anti-squat” of the rear suspension by moving the trailing arm up or down.
-
3-Inch Radius: The mounting saddle is precision-ground to fit perfectly over standard 3-inch axle tubes, providing a clean, professional welding surface.
