Centric 126.66043SL Power Slot Slotted Vented Brake Rotor - Rear Driver Side

The Centric Power Slot 126.66043SL is a slotted, vented rear brake disc designed as an entry-level performance upgrade for trucks, SUVs, and severe-duty vehicles. Engineered for direct-fit installation, this rotor delivers consistent, reliable stopping power under both everyday and demanding driving conditions.

At the heart of this rotor is Centric's proprietary Vac-U-Slot technology. These precision-machined slots actively evacuate heat, gas, and brake dust from the pad-to-rotor interface — the primary cause of brake fade and reduced stopping performance. In wet conditions, the Vac-U-Slots channel water away from the braking surface to maintain firm, confident pedal feel regardless of the weather.

Key Features:

• Vac-U-Slot design evacuates gas, heat, and dust to prevent brake fade
• Slotted surface clears water from the rotor face for reliable wet-weather braking
• Vented disc construction promotes airflow to manage thermal buildup
• Superior thermal crack resistance for long-lasting durability under stress
• Vac-U-Slots milled to minimum disc thickness serve as a built-in visual wear indicator
• Direct-fit replacement — no modifications required
• Natural finish
• 8-lug hub configuration
• Sold individually — Rear, Driver Side (Left) position

Backed by Centric's 90-day or 3,000-mile limited warranty, the Power Slot 126.66043SL is a straightforward performance upgrade that improves braking confidence without requiring a full big-brake conversion.
