CUSTOM WIRING FOR
RACE & OFF-ROAD TRUCKS
Race trucks demand more from their electrical systems than the average street vehicle.
Heat, vibration, dust, rough terrain and high electrical loads can expose weak connections and poorly routed wiring quickly. That's why a race truck electrical system needs to be planned around the vehicle and how it's actually going to be used.
Fastline Wiring & Fabrication provides custom race truck wiring for Scottsdale and the greater Phoenix area, from individual electrical upgrades to extensive custom wiring systems.
Whether you're building a prerunner, desert truck, off-road race truck or heavily modified pickup, we'll work with your build to create a clean, reliable electrical setup.
