From SEMA trucks to best of show winners at most events around the country, you’re bound to see a GSI logo welded into the frame rails of the top built trucks on the planet. Although like almost any great business in this amazing country we call home, the road to respect wasn’t always so smooth. The team at GSI International has been designing and fabricating parts for classic trucks and cars since the shop opened in 2000. Their team is passionate about hot rods and custom cars with a mission to channel that passion into creating quality products. To support the growing demand of their highly engineered products, they officially launched GSI Machine & Fabrication in 2015 specializing in Chevy C10 air-ride suspension. Now they offer a full line of products for classic trucks and shipping to both domestic and international customers.

Along with their own amazing line items, GSI is also an authorized dealer for Accuair, Budnick Wheels, CPP, Currie Enterprises, Ridetech and Wilwood.
