In response to the hot weather, we are implementing a flexible schedule for our mechanics to avoid the peak afternoon heat. Our business hours will remain the same to contact us, and customers can continue to pick up and drop off their vehicles during these times. We will also accommodate late pick-ups and drop-offs as required.

Built for the Mud. Made in Southern Illinois.

You didn’t buy that 4x4 to keep it stock.

At Big Muddy Boyz Offroad Customs in Mount Vernon, we turn pavement princesses into trail legends. Lift kits, mud tires, winches, light bars, custom fab, re-gearing, snorkels — if it crawls, climbs, or sends it through mud holes, we build it right.
• Free walk-around estimates
• ASAP turnarounds before Jeep season
• We don’t install junk. Period.
Stop getting smoked by your buddy’s Jeep. DM us your rig + budget and we’ll spec your build.
