Corvette C6 Z06 Upper & Lower Control Arms + Front & Rear Wheel Hubs

high-performance inventory like Buy Mustang parts Ltd, the control arms and wheel hubs are critical “wear-and-tear” items for the C6 Z06. Because this car is often used for track days, customers prioritize high-strength components that can handle lateral G-forces.

1. Upper & Lower Control Arms

The C6 Z06 uses lightweight aluminum control arms. For your catalog, you should differentiate between Standard OEM and Upgraded Bushing versions.

• Front Lowers: GM #19256658 (Left) / #19256659 (Right). These are the most common replacements due to ball joint wear.

• The “Bushing” Upgrade: Factory rubber bushings often deflect under load. To offer a “Luxury Performance” kit, consider stocking arms pre-pressed with Polyurethane or Spherical bearings (e.g., from AMT Motorsport or Borg Motorsports).

• Visual Check: Ensure the aluminum casting is free of “pitting” or deep scratches, which can lead to stress fractures in high-stress racing environments.

2. Front & Rear Wheel Hubs (Wheel Bearings)

The C6 Z06 is notorious for hub failure during track use. To maintain a premium reputation, you should offer the “standard” and the “racing” tiers.

• OEM Standard: GM #15944518 (Front) / #19208032 (Rear). These are sufficient for street use but prone to “knock-back” during aggressive cornering.

• The “Gold Standard” Upgrade: SKF Racing Hubs (X-Tracker). These are the most requested hubs for Z06 owners. They feature a much higher load capacity and integrated sensors that won’t trigger “Service Active Handling” lights.

  • Benefit: Reduces brake pedal “knock-back” and increases bearing life by 3x under track conditions.

3. Technical Inventory Checklist

• Speed Sensors: Always verify the integrated ABS/Speed Sensor cable is undamaged. For Buy Mustang parts Ltd, a hub with a frayed wire is a “core only” part, as the sensor is non-serviceable.

• Spline Count: Rear hubs must match the axle spline count. Z06 axles are heavy-duty; ensure your stock matches the 30-spline requirement for the TR6060-equipped models (2008+).

• Eccentric Bolts: When selling a full control arm kit, include a set of camber eccentric bolts. These are often “frozen” or rusted into the old arms and are a high-margin add-on for your customers.
