4 Wheel Parts Truck and Jeep Fest | 2026 | Ontario, CA

4 Wheel Parts Truck and Jeep Fest is rolling into Ontario for 2026 with a weekend built around lifted trucks, Jeep builds, off-road gear, and custom vehicle culture.

This one leans more toward a truck and Jeep expo than a traditional car show, which gives it a different kind of energy. Instead of just walking rows of parked vehicles, attendees can expect a mix of custom rigs, product displays, demos, giveaways, and build-focused browsing. For people into 4x4 upgrades, tires, suspension, overlanding gear, lighting, wheels, and trail-ready setups, the event should feel more hands-on than a typical weekend meet.

Organized by 4 Wheel Parts, the event brings together dozens of off-road and truck-focused brands under one roof, with Toyo Tires included as the presenting sponsor. There is a clear shopping side to the weekend, with show-only specials, clearance areas, installation offers, and other event deals in the mix, but the appeal is not only about buying parts. Custom vehicles, product demos, giveaways, and the family-friendly format help give the weekend more of a full truck and Jeep gathering feel.

Happening at the Ontario Convention Center in San Bernardino County, this Inland Empire setting makes sense for a Southern California off-road and 4x4 crowd. Ontario gives the event room to draw enthusiasts from Los Angeles County, Orange County, Riverside County, and the wider IE without feeling tied to one local scene. Expect to see lifted trucks, Jeeps, off-road builds, tow rigs, daily-driven customs, and plenty of vehicles that look ready for dirt, rocks, or weekend trails.

This is not really the place for a quiet chrome-and-lawn-chair kind of show. Truck and Jeep Fest feels more like a weekend for people already thinking about their next upgrade, whether that means tires, suspension, recovery gear, or just getting a closer look at what other builders are running. Bring questions, walk the floor, and expect a practical kind of event built for people who actually use their rigs.
