Arlen Ness Front 4 Piston Caliper For Harley 2006-2026
Modern Performance: Arlen Ness Front 4-Piston Billet Caliper
Transform your Harley-Davidson’s braking system with the Arlen Ness 4-Piston Front Caliper. Engineered to provide a massive increase in clamping force over factory equipment, this caliper is the perfect solution for riders looking to improve safety and control without sacrificing custom style. Designed for 2000–2026 Harley models, it offers a direct bolt-on fit for a wide range of Touring, Softail, Dyna, and Sportster applications.
Performance-Driven Engineering
Arlen Ness combines race-inspired technology with world-class manufacturing:
High-Stiffness Billet Construction: Each caliper is precision CNC-machined from a solid block of 6061-T6 billet aluminum. This rigid design prevents the caliper body from “flexing” under heavy braking, ensuring every ounce of lever pressure is transferred directly to the brake pads.
Aggressive 4-Piston Bite: The four-piston configuration provides a significantly larger surface area of pressure compared to standard 2-piston units. This results in shorter stopping distances and a much more communicative lever feel.
Advanced Cooling Fins: The caliper body features sculpted 3D cooling fins that aren’t just for looks—they increase surface area to help dissipate heat during aggressive riding, preventing brake fade on long descents or in heavy traffic.
The Arlen Ness Custom Aesthetic
Seamless Integration: Designed to flow with the lines of both factory and custom wheels, these calipers provide a high-end “Big Brake” look that instantly cleans up the front end of your motorcycle.
Finish Options: Available in a mirror-like Chrome or a deep Black Anodized finish with machined accents.
Broad Year Range Compatibility: Fits most 2000–2026 Harley-Davidson models (excluding Springer models and certain 2008-up Touring models already equipped with Brembo setups—please verify fitment for 11.8″ vs. 11.5″ rotors).
Technical Details
Direct Bolt-On: Engineered to work with OEM master cylinders and standard brake lines.
Everything Included: Each caliper comes pre-loaded with high-performance DP brake pads, a bleeder screw, and a 10mm banjo bolt.
Single or Dual Disc: Sold individually; for dual-disc models, order one left and one right side caliper.
Elevate your ride with the perfect blend of legendary Ness style and modern braking technology.
