Product Details

The Ksport BKAC040-342SO Slimline Big Brake Kit is a front 3-piston brake upgrade engineered specifically for vehicles where caliper clearance is at a premium. Traditional multi-piston big brake kits often fail to clear the back of aggressive aftermarket wheels or tight factory wheel pockets — the Ksport Slimline solves this problem with a caliper profile that mirrors OEM single-side floating piston caliper thickness, delivering big brake performance without sacrificing wheel fitment flexibility.

Key Features:

  • 3-Piston Slimline Caliper — Single-side piston caliper design maintains a slim profile while delivering enhanced clamping force over stock brakes
  • 13.8 in. (350 mm) Slotted Two-Piece Floating Rotor — Slotted rotor design with an aluminum center hat reduces rotational mass for quicker braking response and shorter stopping distances
  • Forged Aluminum Caliper — Larger brake pad surface area compared to OEM pads for improved braking performance
  • CNC Machined Carbon Steel Caliper Brackets — Precision-machined for accurate fitment and long-term durability
  • Bolt-On Installation — Designed for straightforward installation with minimal tools and no vehicle modifications required in most applications
  • Complete Kit — Includes calipers, floating brake disc, brake pads, and all required hardware
  • 12-Month Warranty — Covers manufacturer defects

Specifications:

  • Rotor Diameter: 350 mm / 13.8 in.
  • Position: Front
  • Caliper Type: 3-Piston
  • Rotor Style: Slotted

The Ksport Slimline Big Brake Kit is the ideal upgrade for enthusiasts who want a genuine performance brake system without compromising their aggressive wheel fitment. Built to order — please allow 4–6 weeks for production and delivery.

Easy deal.

Exactly what I needed

Very easy

good

Autoplicity had the best price on these tires on date of purchase. I had selected this brand quite a while back and so far have been happy with the purchase, quick delivery and initial performance of the tires. I hope to make a future purchase of three additional tires sometime in the future.
