Ksport BKIN420-443SO Floating Rotor Big Brake Kit 4, 6, or 8 Piston Caliper

The Ksport Big Brake Kit delivers ultimate stopping power through advanced brake engineering designed to reduce brake fade, improve pad longevity, and maintain consistent braking performance under demanding conditions. The system integrates modern brake technology to continuously cool and refresh the brake pad surface during braking, keeping performance reliable from the first stop to the last.

Caliper Features:

• Available in 4, 6, or 8 piston opposed piston configurations
• Extreme lightweight one-piece CNC machined billet aluminum construction using aircraft-quality material
• Differential bore configuration for optimized clamping force and even pad wear
• Weighs just over 5 lbs. each for significant unsprung weight savings
• Machined-in protection grooves for bridge tube security
• Aluminum pistons with high-temperature seals for fade resistance
• Stainless-steel brake pad wear plates included as standard
• Opposed piston design improves pad wear and caliper rigidity over OEM calipers

Rotor Features:

• Two-piece disc assembly reduces both rotating and unsprung weight
• Floating disc option available — prevents thermal warping and braking surface cupping under extreme heat
• Unique slot design expels gas and pad debris faster than conventional slot patterns, reducing braking noise
• Every rotor is heat treated and balanced prior to shipment for peak performance
• Cross-drilled rotors run cooler and are recommended for daily-driven vehicles
• Slotted rotors are recommended for track or performance-focused applications

Brake Lines:

• Stainless-steel braided brake lines eliminate hose expansion under pressure for a firm, consistent pedal feel

Designed for straightforward installation with minimal tools required in most applications, the Ksport Big Brake Kit is an ideal upgrade for drivers seeking a proven, high-performance braking solution over factory OEM components.
