Ksport BKHD030-621CO Procomp Big Brake Kit Floating Rotor Piston Caliper - 4 6 or 8

The Ksport BKHD030-621CO Procomp Big Brake Kit delivers a significant upgrade in stopping power over stock braking systems. Engineered to reduce brake fade and continuously refresh the brake pad surface under heavy braking, this kit is a sophisticated bolt-on upgrade designed for easy installation with minimal tools required in most applications.

Lightweight One-Piece Billet Caliper

Each caliper is CNC machined from a single solid billet of aircraft-grade aluminum — never cast or welded — ensuring perfectly uniform thickness and strength throughout the caliper body. This construction eliminates weak points that can lead to fracturing or warpage over time. Weighing just over 5 lbs. each, the calipers feature a differential bore configuration, machined-in protection grooves for the bridge tubes, and an opposed-piston design that improves pad wear consistency and caliper rigidity over the OEM setup. Caliper piston options include 4, 6, or 8 pistons depending on the application.

Key Features:

• Aircraft-grade billet aluminum calipers — CNC machined one-piece construction for maximum strength and corrosion resistance
• Aluminum pistons with high-temperature seals for reliable operation under racetrack heat
• Stainless-steel brake pad wear plates standard on every caliper design
• Opposed-piston design improves pad wear and caliper rigidity over OEM
• 2-piece floating disc assembly — reduces both rotating and unsprung weight
• Floating rotor design prevents thermal stress warping and braking surface cupping under extreme heat
• Unique slot design reduces braking noise and expels gas and pad debris faster than conventional slot patterns
• D.O.T. compliant stainless-steel braided brake lines resist expansion under pressure for quicker pedal response and firmer pedal feel
• Every rotor is heat treated and balanced before shipment for consistent performance
• Compatible with all OEM ABS systems
• Covered by a 12-month manufacturer defects warranty

Rotor Style Options:

• Cross Drilled — runs cooler, recommended for daily-driven street vehicles
• Slotted — superior heat and gas dispersal, recommended for track-focused or performance driving
