Ksport BKSB140-621CO Procomp Big Brake Kit Front 6 Piston 12 in. Cross Drilled Floating Rotor

The Ksport BKSB140-621CO Procomp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to deliver significantly enhanced stopping power under sustained high-heat conditions. Featuring a front 6-piston caliper paired with a 12-inch (304mm) cross-drilled floating rotor, this kit is a direct replacement for your OEM brake system with no vehicle modifications required in most applications.

Aircraft-Grade Billet Aluminum Calipers:

• CNC machined from a single solid billet of aircraft-grade aluminum — never cast or welded — for perfectly even wall thickness and maximum strength
• Weighs approximately 5 lbs. each, delivering significant unsprung weight savings over factory calipers
• Corrosion-resistant construction with machined bridge tube protection grooves
• Aluminum pistons for superior heat resistance and consistent, uncompromised operation
• High-temperature seals and stainless-steel brake pad wear plates standard on every caliper
• Opposed piston design greatly improves pad wear and caliper rigidity versus OEM

Two-Piece Floating Rotor Design:

• Two-piece disc assembly reduces both rotating and unsprung weight
• Floating outer section shifts slightly as needed for better self-centering in the caliper, lowering brake drag and promoting more even pad application
• Floating design eliminates thermal stress warping and disc cupping under extreme heat
• Every rotor is heat-treated and balanced before shipment for optimal performance
• Cross-drilled rotor style runs cooler and is recommended for daily-driven vehicles

DOT-Compliant Stainless-Steel Braided Brake Lines:

• Eliminates hose expansion under pressure for a firmer, more responsive pedal feel
• Quicker pedal response compared to OEM rubber brake lines
