Overview

The DBA 4000XS is a premium, cross-drilled and slotted brake rotor designed for performance street applications. It features DBA's patented Kangaroo Paw ventilation system and an XS precision CNC machined slot and cross-drilling pattern to increase out-gassing exit points, enhancing braking consistency and effectiveness.

Constructed from proprietary XG-150 high carbon alloyed iron with Thermal Stability Profiling (TSP), these rotors offer increased thermal capacity to handle extreme heat, minimizing warping and cracking. The universal drill and slot design eliminates the need for separate left and right discs, simplifying installation. The rotors also include thermographic temperature monitoring markings that change color to indicate peak braking temperatures, aiding in rotor fatigue assessment and warranty claims. Non-friction areas are protected with paint to reduce corrosion and enhance appearance.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
