Atlas Park Brake Kit
The Northwest Fab Atlas Park Brake Kit is designed to fit both driver-side and passenger-side Atlas transfer case configurations.
At the heart of the system is a CNC-machined billet 6061 aluminum Atlas Transfer Case Support featuring a multi-position clocking pattern. This allows the transfer case to be rotated for optimal driveline angles, crossmember placement, skid plate clearance, and overall chassis packaging.
A bolt-on caliper mounting bracket attaches directly to the transfer case support, creating a rigid, serviceable mounting solution. Both the support and caliper bracket are CNC-machined in-house from billet 6061 aluminum to ensure precise fitment, maximum strength, and long-term durability in demanding off-road conditions.
The kit utilizes a 10-inch Wilwood rotor and is available with either a Wilwood Electronic Park Brake (EPB) or Wilwood MC4 Mechanical Park Brake Caliper, providing reliable holding power without relying on your vehicle's hydraulic braking system.
The Electric Park Brake option includes the Wilwood EPB controller, wiring harness, and switch for convenient push-button operation. Mechanical versions are available in both left-hand and right-hand caliper configurations.
Every kit is designed to package cleanly behind the transfer case without affecting driveshaft clearance or suspension travel and includes all hardware required for installation.
