WCFab Open House

Saturday, October 3, 2026 9:00 am - 4:00 pm

One of Illinois’ biggest diesel truck events is back! The biannual WCFab Open House brings together some of the coolest custom and classic trucks, Jeeps, and Broncos in the Midwest for a full day of fun.

We’ve got something for everyone, including a dyno competition, show and shine awards, raffles, and an auction. You’ll have the chance to see some of the highest horsepower trucks in the Midwest compete for $11,000 on the dyno, check out top-tier builds up close, and talk directly with the brands behind your favorite parts. Plus, there’s plenty for the kids with pedal pulls and bounce houses.

Spectator admission is free! Raffle, Live Auction, Show & Shine, and the Dyno Competition proceeds support local students pursuing careers in the trades through the Wehrli Custom Fabrication Scholarship Fund in partnership with the DeKalb County Community Foundation. Since 2022, we’ve raised over $48,000 towards the fund!

This is a family-friendly event built around supporting the next generation of enthusiasts. Please note that we have a zero-tolerance policy for inappropriate behavior, including loud music, speeding, and burnouts.
