StopTech Slotted Rear Brake Rotors 99.5-04 Ford SuperDuty

Excessive heat can cause resins in your brake pad to vaporize or "outgas." As the brake pad wears, the used friction material turns into a fine dust. This boundary layer of heat, gas and dust builds up between the pad and rotor surfaces and inhibits performance. Here's where StopTech's slotted brake rotors make a big difference. StopTech's exclusive Vac-U-Slots are machined into the rotor and help evacuate gasses and dust, shed heat, and keep the brake pad surface clean. And in wet, raining conditions, the Vac-U-Slot helps push water off the braking surface for better stopping power. StopTech rotors are finished in a durable black e-coat on the hat, edges and internal vanes to prevent corrosion. The braking surfaces are left in a bare iron finish to improve brake pad bed-in. StopTech slotted rotors will deliver superior, reliable braking for your truck, even under hard driving and severe duty conditions. IMPORTANT NOTE: ***Will Not Fit Early 1999 Model Years produced before 12/7/98.
