J.C. Whitney JSTPS27110049 Front Brake Disc Rotor OEM Replacement 22666578

The J.C. Whitney JSTPS27110049 is an OEM-replacement front brake disc rotor engineered to match the original factory specifications of General Motors vehicles. Replacing worn or warped rotors restores consistent, confident stopping power and helps eliminate common symptoms such as brake pedal pulsation, vibration, and grinding noise.

Key Features:

• OEM Cross-Reference: Direct replacement for GM part number 22666578
• Precise Factory Fit: Manufactured to original equipment dimensions including diameter, thickness, and hub bore for a bolt-on installation with no modifications required
• Balanced Construction: Cast iron construction delivers durability under the heat and pressure of repeated braking cycles
• Symmetrical Design: RH = LH fitment — a single part number serves both the driver and passenger sides
• Front Axle Application: Designed specifically for the front braking system where the majority of stopping force is applied

This rotor is a direct-fit solution for vehicles currently equipped with GM OEM part 22666578. For best results, rotors should be replaced in pairs along with fresh brake pads to ensure even wear and optimal braking performance.
