The Shop

Insanity Customs started with a simple idea: build the kind of shop we'd want to take our own trucks to. Honest answers, clean work, and horsepower that survives the drive home.

Classic Car Restoration

Complete custom builds for older cars and trucks — body and paint, chassis, brakes, interior, wiring and modern drivetrains. We don't build engines in house; we source the right combination and install, plumb and calibrate it so the car is as dependable as it is beautiful.

We work on diesel and gas, daily drivers and trailer queens, late model and old iron. Same standard on all of it.
