Product Details

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotor construction and finish details that matter in brake service. This rotor uses a plain disc finish with a black-coated hat section, while the slotted X-drilled surface is engineered for a directional front axle position. For Jeep Wrangler owners searching for a front left brake rotor, 633-42038L provides the specified dimensions and surface design needed for the listed applications.

This part fits 2023-2025 Jeep Wrangler, front left with performance front brake pads; 2022 Jeep Wrangler, front left with standard front brake pads; 2020-2021 Jeep Wrangler, front left with heavy duty brakes and 342 mm rear disc; and 2018-2021 Jeep Wrangler, front left. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced pad contact from heat-affected or scored rotors
• Surface rust on exposed rotor hats and braking components
• Brake fade concerns during repeated stops or heavier use
• Noise and vibration associated with rotor wear

Installation Notes

Verify rotor dimensions, bolt pattern, and left-side front fitment before installation. This rotor is directional, so orientation matters during service. Inspect brake pads, caliper condition, and hub surfaces at the same time to confirm even contact and proper rotor seating on Jeep Wrangler front brake systems.

Quality Assurance

Dynamite Friction’s DFC Brake Rotor - Drilled and Slotted - Black line uses a rust-resistant coating and black zinc hat finish to support long-term appearance and corrosion protection in normal service conditions.
