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.
