Stoptech 126.65143SR Disc Brake Rotor - Rear Right

Overview

StopTech Sport Slotted Disc Brake Rotors, part number 126.65143SR, are direct replacement brake discs for factory brake systems and stock calipers. This rear right rotor is built for Ford Super Duty applications and uses slotting to help manage heat, brake dust, and pad glazing while improving bite in wet and dry conditions.

Key Features

• 1-piece direct replacement rotor for factory brake systems.
• Slotted surface helps disperse heat and brake dust.
• Vented design supports more consistent braking performance.
• Black e-coating helps protect against corrosion.
• High-carbon metallurgy in most applications supports quieter operation and improved crack resistance.
• Behind-the-hub mounting with 8 bolt holes and a coated hat finish.

Detailed Description

StopTech designed this slotted brake rotor for drivers who want a direct-fit upgrade over a standard replacement disc. The 14.291-inch outside diameter, vented construction, and straight vane design work together to support stable braking under repeated use. The coated finish and black e-coating help resist corrosion, making this rotor a practical choice for Ford F-250 Super Duty and Ford F-350 Super Duty rear right brake service. Part number 126.65143SR is a fitment-specific rotor for applications that use stock calipers and factory brake hardware geometry.

StopTech Sport Slotted Disc Brake Rotors focus on controlled pad contact and heat management rather than cosmetic changes alone. That makes them a strong option when you want a replacement rotor that addresses brake dust buildup, glazing, and fade-related performance loss without changing the factory brake system layout. The 126.65143SR rotor is also a useful match for Super Duty trucks that see frequent towing, hauling, or stop-and-go use.

What It Helps Solve

• Brake fade from heat buildup during repeated stops.
• Pad glazing that can reduce initial bite.
• Brake dust accumulation on the rotor surface.
• Corrosion on exposed rotor surfaces.
• Quieter operation concerns in high-carbon applications.

Installation Notes

Compatible with factory brake systems and stock calipers. Verify rear right fitment before ordering, since this application includes year-specific notes for certain Ford F-250 Super Duty and Ford F-350 Super Duty models. Part number 126.65143SR should be matched to the vehicle’s brake configuration and mounting dimensions before installation.

Quality Assurance

StopTech Sport Slotted Disc Brake Rotors are engineered as direct replacement brake discs with corrosion protection and performance-focused slotting. The brand’s rotor design emphasizes consistent braking behavior, improved wet and dry response, and durability for demanding service.
