The 15069 eliminates the difficulty of hand-fabricating a mounting plate with the correct bolt pattern and center-bore clearance. CNC-cut for absolute accuracy, this plate is designed to be welded directly to your A-arm tubing. It provides a flat, rigid surface that prevents the ball joint from "rocking" or loosening under the heavy vertical and lateral loads of circle track racing.
Detailed Technical Specifications
1. Precision CNC Geometry
-
Exact Bolt Pattern: Features the industry-standard 3-bolt pattern for Small GM Metric ball joints. This ensures that the mounting hardware is perfectly vertical and aligned, preventing stress risers on the bolts.
-
Optimized Center Bore: The center hole is precision-clearanced to allow the ball joint housing to seat flush against the plate, providing a stable foundation for the suspension pivot.
-
Lightweight yet Strong: The plate thickness is engineered to handle the high-torque loads of racing without adding unnecessary unsprung weight to the front end.
2. Fabricator-Friendly Design
-
Weldable Steel Alloy: Crafted from high-grade steel that is compatible with both MIG and TIG welding. It takes heat well, allowing for a deep-penetration weld to your control arm tubing.
-
Symmetrical Profile: Designed with enough "meat" around the edges to allow the fabricator to notch-fit their A-arm tubes at various angles to achieve custom caster and camber settings.
-
Raw Finish: Arrives in a clean, raw state, ready for immediate welding and final coating.
3. Compatibility & Maintenance
-
"Metric" Standard: Optimized for the small bolt-in ball joints commonly used on Monte Carlos, Regals, and Cutlasses, as well as many aftermarket tubular A-arms.
-
Service Ease: Because it uses a bolt-in style joint, once this plate is welded to your arm, ball joint changes become a simple "unbolt-and-replace" task in the pits.
