Stoptech 126.65143SL Disc Brake Rotor - Rear Left

Overview

StopTech Sport Slotted Disc Brake Rotor 126.65143SL is a 1-piece direct replacement rotor for factory brake systems and stock calipers. It uses a slotted, vented design with a coated hat finish to support stronger braking response and corrosion protection.

Compatible with Ford F-250 Super Duty and Ford F-350 Super Duty rear left applications, this rotor is built for drivers who want a direct-fit brake upgrade with OE-style installation characteristics. The 126.65143SL part number is also useful when verifying the correct rear left rotor for your truck.

Key Features

• 1-piece direct replacement disc brake rotor for factory brake systems
• Slotted surface helps clear heat and brake dust while reducing pad glazing
• Vented rotor design supports improved airflow and braking consistency
• Black-coated hat finish helps resist corrosion
• High-carbon metallurgy is used in most applications for quieter operation and added crack resistance
• Fits rear left Ford Super Duty brake applications

Detailed Description

StopTech Sport Slotted Disc Brake Rotors are engineered for drivers who want a direct replacement rotor that works with stock calipers and factory brake hardware. The slot pattern helps maintain pad bite in wet and dry conditions, while also promoting heat and dust dispersal during repeated stops. The vented construction and coated finish add durability for demanding truck use. If you are replacing a rear left rotor on a Ford F-250 Super Duty or Ford F-350 Super Duty, part number 126.65143SL provides a fitment-specific solution that matches the application listed here.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

• Correcting brake pulsation caused by worn rotor surfaces
• Replacing a rotor with glazing, scoring, or heat spots
• Restoring braking response after corrosion or pad transfer buildup
• Addressing reduced wet-weather brake bite
• Updating a rear left brake rotor on compatible Ford Super Duty trucks

Installation Notes

Install on the rear left position only for the listed Ford applications. Verify rotor dimensions, hub fitment, and brake system configuration before installation. Clean the mating surfaces and inspect pads, caliper condition, and wheel hardware during service. Part number 126.65143SL should be matched to the vehicle application before assembly.

Quality Assurance

StopTech designs this rotor as a direct replacement for factory brake systems and stock calipers. The slotted surface, coated hat, and high-carbon metallurgy used in most applications support durability, corrosion resistance, and consistent braking performance.
