We stock and carry all Firestone

Welcome to the Insane Designs Web Site. We do everything from small drops to complete frame rebuilds. We are a custom fabrication shop, not a bolt on shop.

If you're looking for a competent, reliable, established and well-known custom fabrication facility, then you found it. Insane Designs was founded in 1994 by Mike Farmer.

Since that time, we have built some of the lowest and cleanest trucks in the DFW area. We also had over a dozen trucks featured in various national magazines.

Please take a look around and get a very small sample of the work we do. Please note that some pics are very old, especially in the mini-truck section. We are constantly updating the website, now more than ever. So check back often.

If you have any questions, please feel free to call anytime Monday - Friday at (972) 875-4312. We are by appointment only or you can email and we'll get back with you as quickly as possible.
