Product Details

The Ksport BKBM031-445SO DualComp Big Brake Kit is an all-in-one dual-function braking solution engineered for drivers who demand independent control over both their foot brake and handbrake systems. Unlike conventional big brake kits, Ksport's innovative DualComp system integrates a single 4-piston caliper that splits its function across two dedicated circuits — 2 pistons dedicated to the foot brake and 2 pistons dedicated to the handbrake — each operating fully independently on its own hydraulic system.

Key Features:

  • Dual-function 4-POT caliper — 2 pistons for foot brake, 2 pistons for handbrake, independently operated
  • Floating brake disc included for improved heat dissipation and reduced brake fade
  • Complete bolt-on kit — no fabrication required, bolt directly to OEM mounting points
  • High-performance brake pads included and ready to install
  • All required hardware and installation components included in the box
  • Designed for enhanced stopping power and precise brake bias control

What's Included:

  • 4-Piston DualComp Caliper(s)
  • Floating Brake Disc(s)
  • Performance Brake Pads
  • All required mounting hardware

The Ksport DualComp Big Brake Kit is ideal for performance and motorsport applications where a dedicated handbrake circuit is essential, such as rally, drifting, and track driving. The complete bolt-on design makes installation straightforward, delivering a significant upgrade in braking performance and control over the stock setup.

Great prices

Everything is all good.

Quick and easy to order.

Great price. Fast shipping

I ordered on Sat. Dec 29th. With the new year holiday, I expected package to arrive on Wednesday. Was told it would arrive Thursday by the end of the day. I did not receive it until Friday afternoon.. In short, they shouldn't say 2 day delivery, since it took 6 days. I am however very happy with the product I ordered.
