Enhanced Braking Power and Aesthetic Upgrade
The Arlen Ness 15" Front Big Brake Rotor Kit (left side) is designed to deliver a significant boost in braking performance for Harley-Davidson Softail 2018–2025.
Its 15-inch diameter offers a larger braking surface and better heat dissipation compared to the stock system. The rotor is made from 420 stainless steel and is strategically drilled to optimize heat evacuation, maintaining consistent performance even under demanding use.
The black anodized 6061 billet aluminum inner carrier ensures structural strength and a lasting premium look. The kit includes a machined adapter bracket that allows you to reuse the original brake caliper, accommodating the rotor's larger diameter.
Easy bolt-on installation, also reusing the original brake line. Compatible with OEM or aftermarket fenders.
