Warn Automotive

What Warn Automotive does

Warn Automotive, LLC, founded in 1948 and headquartered in Milwaukie, Oregon, designs and manufactures powertrain disconnect technology for 4WD and AWD vehicle systems. The company was re-established as a wholly-owned subsidiary of Dover Corporation within its Vehicle Service Group following the 2017 separation of the WARN Automotive brand and torque transfer technology from WARN Industries (which was sold to LKQ Corporation). Warn operates a Technical Center in Livonia, Michigan, holds ISO 9001:2015, ISO 14001:2015, and IATF 16949:2016 certifications, and produces over 4 million patented disconnect products annually with a stated zero-defects manufacturing commitment.

The product portfolio comprises three core categories: Integrated Wheel End Disconnect Systems (Electric IWE, Solenoid IWE, and Vacuum IWE variants with shift times ranging from 50ms to 500ms and torque capacities up to 6,000 Nm), Front Axle Disconnect Systems (Electro-Magnetic Pulse Disconnect and Electronic Center Disconnect Actuator), and Manual and Automatic Hub Locks (covering half-ton through Class 6 truck applications). A growing share of the portfolio is engineered specifically for BEV/PHEV platforms, where axle and wheel-end disconnects enable deactivation of secondary drive units to deliver 3-7% energy savings and extended battery range. The company holds an extensive patent portfolio in the US and internationally covering its disconnect technology.

Warn Automotive operates as a Tier 1 and Tier 2 B2B supplier to OEM manufacturers, with custom-engineered components integrated into vehicle platforms from early specification through production. The customer base spans commercial heavy-duty trucks, pickup trucks, SUVs, passenger cars, and electric vehicle programs across global automotive markets. Named customer recognition includes Ford Motor Company World Excellence Awards (Gold Winner, 2013 and 2014). Pricing is quote-based on custom-engineered applications with no public pricing, and revenue is generated through hardware sales under OEM contracts.

Products and services

• Electric Integrated Wheel End (EIWE) Electric motor-actuated wheel end disconnect for OEM integration into 4WD/AWD vehicles, shifting in 500ms with closed-loop feedback for diagnostics and automatic 4WD engagement without driver intervention. Designed for automotive OEM platforms requiring reliable on-demand four-wheel-drive activation.
• Solenoid Integrated Wheel End (SIWE) Solenoid-actuated wheel end disconnect with 50-millisecond shift time and up to 1 million durability cycles, designed for BEV applications requiring minimal energy consumption. Sold to OEMs for integration into electric vehicle platforms where low power draw and ultra-fast engagement are critical.
• Vacuum Integrated Wheel End (VIWE) Self-contained vacuum-actuated wheel end disconnect that serves as a lower-cost solution for less technically advanced trucks, with mono-stable default state. Targeted at commercial heavy-duty and pickup truck OEMs seeking cost-effective disconnect functionality.
• Electro-Magnetic Pulse Disconnect Full front axle disconnect assembly using electro-magnet actuation with less than 120ms shift time and 250,000 durability cycles, enabling active AWD shift strategy for high-performance vehicles. Supplied to OEMs for integration into performance-oriented SUV and passenger vehicle platforms.
• Electronic Center Disconnect Actuator (ECDA) Electric motor-actuated center disconnect for part-time 4WD/AWD applications, configurable as standalone actuator or full disconnect assembly with housings and shafts. Sold to OEMs for center-mounted driveline integration in trucks and SUVs.
• Automatic Hub Locks Vacuum-actuated automatic hub locks (pulse or constant vacuum) with mono-stable or bi-stable configuration options, providing ease of use for commercial heavy-duty vehicles. Available in multiple torque capacities from half-ton (4500 Nm) to Class 6 truck (22,000 Nm) applications.
• Manual Hub Locks Cost-effective manual hub locks enabling flat towing for electric vehicles by preventing unnecessary regeneration during towing and protecting the electric motor from damage. Warn Automotive is the only OEM manual hub lock provider, supplying OEMs with EV-friendly flat-tow solutions.
