About ICT Billet

ICT Billet was born from a passion for LS swaps. After tackling our first swap in 2001, we saw the need for better parts and reliable information. In 2014, we launched ICT Billet to provide high-quality, American-made parts that simplify and enhance LS and LT swaps.

We’re dedicated to supporting car enthusiasts with precision-engineered products, detailed installation guides, and world-class service. Thank you for choosing ICT Billet—your partner in making exceptional builds a reality.
