These pads are the original REAR Alcon pads provided in your AO Sprinter 2500 Big Brake Upgrade braking kit.
Alcon has designed a 30% larger pad allowing for less work needed per pad surface area resulting in lower temperatures and more braking torque. This compound reflects the knowledge and experience gained from military and VIP protection vehicles over the years. Performance & Durability, often in uncompromising surroundings, are pre-requisites for Armored Vehicle braking solutions.
