Alcon BKF1559AX100 RAM TRX 376x42mm 6-Piston Front Big Brake Kit - Black Calipers

The Alcon BKF1559AX100 is a front big brake upgrade kit engineered specifically for the 2021+ RAM TRX, featuring massive 376x42mm (14.8" x 1.65") vented rotors paired with 6-piston ductile iron calipers finished in black. Developed from Alcon's motorsport and armored vehicle programs, this kit delivers a substantial and measurable improvement over the stock braking system.

Performance Gains Over Stock:

• Up to 12% increase in available thermal mass
• Up to 8% reduction in pad work rate, extending pad life
• Up to 7% increase in available brake torque
• Up to 15% reduction in pedal effort for improved driver confidence

Key Features:

• 6-Piston Calipers: Ductile iron caliper housings provide maximum strength, stiffness, and high resistance to impact and fatigue
• Massive 376x42mm Rotors: Significantly thicker than OEM and most aftermarket rotors, dramatically increasing thermal capacity and reducing brake fade potential
• High-Temperature Seals: Seal material sourced from Alcon's highest-level motorsport applications
• Wiper Seal on Every Piston: Provides dirt exclusion for reliable performance in off-road and adverse conditions
• Black Epoxy Acrylic Finish: Applied over an acid zinc base for maximum corrosion protection
• High-Friction Brake Pads: Included pads increase stopping power and thermal performance
• OEM-Compatible Design: Fully plug-and-play; compatible with the stock master cylinder, ABS system, and OEM parking brake — no extensive modifications required
• OEM Wheel Fitment: Designed to fit stock 18" wheels and many 18"+ aftermarket wheels

This kit is a direct application of technology derived from Alcon's off-road racing and armored vehicle programs, purpose-built around the TRX platform. Everything needed for installation is included.
