Ksport BKHD231-621CO Floating Rotor Big Brake Kit 4, 6, or 8 Piston Caliper

The Ksport BKHD231-621CO is a high-performance big brake kit featuring a full-floating 2-piece rotor assembly with your choice of 4, 6, or 8 piston caliper configurations. Engineered to significantly reduce brake fade and continuously cool and refresh the brake pad surface under hard braking, this kit delivers a dramatic upgrade in stopping power over the stock brake system. Installation is straightforward and requires minimal tools in most applications, with no vehicle modifications needed.

Caliper Construction:

• CNC machined from aircraft-quality billet aluminum in a one-piece construction — no casting or welding
• Differential bore configuration for optimized pad clamping force
• Opposed piston design improves pad wear evenness and caliper rigidity over OEM
• Weighs approximately 5 lbs. each, delivering significant unsprung weight savings
• Machined-in protection grooves for bridge tubes
• Aluminum pistons with high-temperature seals for superior heat resistance
• Stainless-steel brake pad wear plates standard on all caliper designs

Floating 2-Piece Rotor:

• Full-floating disc assembly reduces both rotating and unsprung weight
• Floating outer ring allows slight lateral movement for better self-centering in the caliper, reducing brake drag
• Eliminates thermal stress warping and braking surface cupping caused by extreme heat
• Every rotor is heat treated and balanced before shipment for consistent, reliable performance
• Unique slot design expels gas and pad debris faster than conventional designs while minimizing brake noise
• Available in Cross Drilled or Slotted rotor styles

Rotor Style Guide:

• Cross Drilled: Runs cooler — recommended for daily-driven street vehicles
• Slotted: Superior heat and gas dispersal — recommended for track and performance use

Brake Lines & Additional Features:

• D.O.T.-compliant stainless-steel braided brake lines included as standard
• Stainless-steel lines resist expansion under pressure for a firmer, more responsive pedal feel
• All OEM ABS systems remain fully functional with this brake kit
• Backed by Ksport's 12-month warranty covering manufacturer defects

Whether building a performance street car or a dedicated track machine, the Ksport BKHD231-621CO big brake kit provides the braking confidence to match your vehicle's power. Note: Built to order — please allow 4–6 weeks for production and delivery.
