*LTS ('Y' Compound Code)* Hawk Performance has applied their severe-duty brake pad friction technology to the braking demands of trucks and SUVs. Heavier vehicles with larger brake systems are more likely to experience higher temperatures, requiring a brake pad that has excellent heat dissipation characteristics. The new LTS (Light Truck & SUV) Brake Pad Compound utilizes Hawk Performances established and proven Ferro-Carbon formulation to provide superior stopping power for full-sized light trucks, SUVs and vans without noise and dust. * Improved Braking Over OE * Superior Fade Resistance * Low Dust * Excellent Pad and Rotor Life * Virtually Noise-Free *Superduty ('P' Compound Code)* Hawks SuperDuty Ferro-Carbon material is engineered for severe-duty professional truck fleets and trucks and SUVs towing heavy loads. This material offers unmatched braking performance under high inertia and/or repetitive braking applications. To drive safely with heavy payloads it is critical to have brakes that operate properly. Heavy fleet trucks and light trucks and SUVs carrying heavy tow loads experience high braking temperatures. Higher temperatures contribute to premature brake pad and rotor wear. Hawk Performances SuperDuty product is a sophisticated material that has an extremely high coefficient of friction designed to provide maximum truck and SUV stopping power with excellent high temperature heat dissipation. Upgrade your fleet or tow vehicles braking performance with Hawk Performances SuperDuty, Sever-Duty compound! * Extremely high coefficient of friction * Extremely high fade resistance * Superior High Temperature Performance * Excellent Rotor and Pad Wear
