The 15022 takes the hardest part of building an A-arm—getting a perfect, symmetrical bend—and does it for you. This tube is precision-bent using industrial mandrel equipment to ensure there is no thinning of the tube walls or "kinking" at the radius. Fabricators can then cut the legs to their desired length and weld them to their choice of inner pivots and ball joint housings to create a custom-offset arm.
Detailed Technical Specifications
1. Precision Mandrel Bending
-
Consistent Wall Thickness: Unlike "crush" bends that weaken the metal, JOES mandrel-bent tubing maintains its structural integrity throughout the curve, essential for a part that carries the load of the front tires.
-
Symmetrical Geometry: Provides a perfectly centered "hoop" that allows for even clearance around shock towers and coil-over springs.
-
Weld-Ready Surface: Arrives in a raw steel finish, prepared for immediate notch-fitting and high-penetration welding.
2. Custom Geometry Freedom
-
Variable Lengths: By providing the "Hoop" separately, JOES allows the builder to determine the exact length and "lead" of the A-arm to achieve specific caster and camber gain characteristics.
-
Standard Tube Diameter: Designed to match industry-standard A-arm components, making it compatible with most ball joint buckets and screw-in sleeves.
-
Rigidity-First Design: The steel alloy is selected for its ability to resist "bowing" under the extreme vertical and lateral loads of dirt and asphalt racing.
3. Cost-Effective Repair Solution
-
Crash Replacement: If a driver "clips" a wall or another car, the hoop is often the first part to bend. This DIY tube allows teams to repair expensive custom arms rather than replacing the entire assembly.
-
Pro-Shop Standards: Gives the home-builder the same material quality found in JOES factory-assembled A-arms.
