The Alcon PNS4415X511.4 is an AV1 Hi Performance compound brake pad set sized for Alcon's front big brake kit fitment on the 2018-2024 Jeep Wrangler JL. Built as a replacement pad for the Alcon BKF1551K06 kit, the PNS4415X511.4 uses Alcon's AV1 friction compound to deliver consistent stopping power across street driving, towing, and off-road use without excessive noise or dust. Because the PNS4415X511.4 is matched to the exact caliper and rotor geometry of the Alcon big brake kit, pad clearance and bite feel stay consistent with the original kit installation.

Shop Alcon big brake kits, calipers, rotors, replacement rings, brake pads, brackets, service hardware, and rotor temperature products by exact manufacturer part number. Match the complete vehicle, axle position, factory brake package, rotor dimensions, caliper family, wheel clearance, and included components before ordering. Alcon Big Brake Kits Alcon brake kits combine application-specific calipers, rotors, brackets, pads, lines, and installation hardware in front, rear, or complete-vehicle configurations. Piston count and rotor diameter do not establish fitment by themselves; the hub, knuckle, axle, factory brake package, wheel barrel, spoke profile, and kit part number must all match. Race, Street, Truck, and Off-Road Applications Select the brake system for the vehicle's actual use. Repeated track braking, towing, larger tires, added vehicle mass, and off-road driving can require different rotor capacity, pad compound, heat management, and service intervals.
