The Evolution of JBM Automotive Excellence
The Legacy of the Mail-Order Era
Long before the internet changed the industry, JBM was a national authority in the truck world. Founded in late 1986 in the City of Orange, we quickly grew from a local "hole in the wall" into one of the country's premier mail-order houses. Our sales teams handled thousands of calls daily as JBM became a household name in the pages of Truckin' and Sport Truck magazines.
We didn't just sell parts; we fueled the custom truck movement, shipping chrome conversion packages and specialty accessories to enthusiasts across the nation who trusted the JBM name for their builds.
A 40-Year Journey
"Our business was built on the front lines of the automotive aftermarket. That 40-year perspective is exactly why we can solve technical problems that other shops haven't even encountered yet."
The Corona Technical Complex
Today, JBM operates out of our state-of-the-art manufacturing facility in Corona. This isn't just a retail shop—it is the headquarters for four world-class automotive brands.
This unique synergy between our retail shop and our manufacturing divisions gives our Master Technicians direct access to the engineers who design the gear. When we work on your vehicle, you are benefiting from factory-level expertise that no "chain shop" can match.
Technical Mastery & High-End Labor
By combining the world-renowned gear-work of Unitrax with our decades of suspension evolution, JBM Offroad has become the destination for labor that requires Seasoned Specialists. From complex re-gearing and locker installations to complete transformations, we treat every vehicle with meticulous, excellent workmanship.
A Commitment to Accountability
"In an era of corporate-owned chains and high-turnover staff, JBM remains a family-owned, owner-operated institution. For nearly 40 years, I have stood behind every differential we re-gear and every suspension we tune. We don't just 'install parts'—we take responsibility for the safety and performance of your vehicle. When you bring your truck to JBM, you aren't just a work order; you are part of a four-decade legacy of automotive excellence."
