Webb Wheel Product's UltraGrip air disc brake pads are designed for superior wear properties, stopping power, and rotor friendliness, and have been dyno and fleet tested for quality. They are available in three formulations for different degrees of application: Plus, Premium, and Severe-Duty. Each pad option comes boxed as an axle set with the appropriate OEM grade hardware, color-coded to help identify them to ensure technicians pull the right set when they are needed for service. They are also ECE R90-compliant, and meet or exceed FMVSS-121 criteria.
