Most marketplaces can sell a box. We support the entire brake system lifecycle for as long as you own it.
Alcon brake kits are engineered systems, not assembled collections of parts.
Each kit is designed with:
This results in more consistent pedal feel, better heat management, and superior durability compared to budget or generic big brake kits.
No. Alcon brake kits are application-specific.
Vehicle weight, intended use, rotor size, caliper configuration, and pad compound all matter—especially on high-performance cars and trucks. Selecting the wrong configuration or pad compound can reduce braking performance, increase noise, or accelerate wear.
This is why buying from the specialist distributor, Alconkits.com, matters.
Manufactured by CTEK, we recommend this as being suitable for the following driving styles:
This is THE question to ask. Alcon brake systems are fully serviceable.
When you purchase from Alconkits.com, you have long-term access to:
This is a major advantage over marketplace sellers who may not support the product after the sale. We know what fits, we stock it, and we don't sell you parts you don't need.
Alcon brake kits are built to deliver higher performance, durability, and consistency than OEM or budget aftermarket brakes.
The cost reflects:
This is not a cosmetic upgrade—it is a functional braking system designed for demanding use.
