Description
The 15026-S is the “Shaft Only” version of the bearing-pivot assembly. It is specifically designed to work with spherical bearings rather than traditional bushings. By moving the pivot point to a precision bearing, the A-arm can move through its travel with zero resistance, allowing the shock and spring to have total control over the tire’s contact patch.
Detailed Technical Specifications
1. Aerospace-Grade 7075-T6 Aluminum
-
Massive Weight Reduction: Significantly lighter than standard steel shafts, reducing the overall weight of the front clip.
-
High Strength-to-Weight Ratio: 7075-T6 aluminum offers the structural integrity of steel but at a fraction of the weight, ensuring it can handle the high-G loads of cornering.
-
Hard Anodized Finish: Typically features a hard-coat finish to provide a durable, wear-resistant surface where the bearings or spacers interface with the shaft.
2. Bearing-Specific Architecture
-
Zero-Stiction Pivot: Designed specifically for use with spherical bearings. This setup eliminates the “binding” that occurs with rubber or polyurethane, resulting in a suspension that reacts instantly to track imperfections.
-
Precision Machining: The shaft is turned to exacting tolerances to ensure a perfect fit within the bearing inner race, eliminating “clunking” or unwanted movement.
-
Centered Geometry: Engineered to provide the correct spacing for standard A-arm mounts, maintaining your carefully set caster and camber angles.
3. Serviceability & Maintenance
-
Replacement Core: Because this is the “Shaft Only,” it allows racers to refresh their A-arms if a shaft becomes nicked or bent in a collision without having to purchase a completely new bearing kit or arm assembly.
-
Clean Installation: The aluminum construction resists the rust and corrosion that can seize steel shafts into the chassis mounts.
