Description:

PERF ROT LF (GSMP)

ACDelco Specialty Performance (Severe Duty) Disc Brake Rotors provide reliable vehicle braking power. They feature a thickness variation that helps to minimize pedal pulsation, noise, and help to extend brake pad life. These brake rotors meet the SAE standard for structural integrity with OE matched material, delivering guaranteed performance. Black and gray fusion coating provides corrosion protection. These rotors are uniquely designed for off road vehicles, SUVs, trucks, and fleet trucks. ACDelco Specialty Performance (Severe Duty) Disc Brake Rotors are ready to be installed right out of the box - no machining required. ⚠ WARNING: Cancer and Reproductive Harm - https://www.P65Warnings.ca.gov

Features and Benefits:

  • Damped iron metallurgy reduces noise and dissipates heat
  • Match OE vane configuration for reduced brake wear and optimal cooling
  • Mill balanced to reduce vibration
  • Non-directional rotation eliminates the need for unique left and right designations
