It’s not too often you see a Sonoma—GMC’s S-10 counterpart—built with such quality and attention to detail that the caliber is comparable to a full-on race truck. So when we saw this one, we knew we had to get some photographic evidence.
After attending a desert race with his father at the age of 14, Ryan Bosman came home with one goal: Build a truck so he can play in the desert, too. And he and his dad picked up this little Sonoma the very next day. Over the course of 10 years—working a $10-an-hour job and scraping together every dime while also attending college for manufacturing engineering—Ryan completed his truck’s first stage. He built a mild front end for his Sonoma and used Deaver rear leaf springs on his truck’s rear end. As Ryan’s skills progressed, his desire to truly build an ultra-capable truck grew. He tore the truck down for one last time. The final iteration of Bosman’s soaring Sonoma is one of the cleanest S-10 builds you will ever come across.
The truck was equipped with Baja Customs lower control arms and frame plating, while Ryan built his own knuckle and upper A-arms to cycle a total of 17 inches of travel. Ryan then ditched the little 2.2-liter four-banger for a 4.3-liter V-6 powerplant.
After that, things got really serious. The whole back of the frame was removed in favor of a tubed back half with a three-link he designed and built, cycling 28 inches of travel.
We caught up with Ryan during the Annual DezertDimes.com Barstow Meet, a camping trip in the Barstow desert. Rain poured from the sky for the first two days, but Sunday morning brought some clear skies in time to get the photographic evidence we wanted.
