A long-standing customer of ours recently experienced theft of his truck, which was subsequently abandoned in a river. Fortunately, only the front end was submerged in water up to the bumper. It's notable that even brief exposure to water can cause extensive damage. Therefore, we are taking proactive measures by flushing all fluids, replacing filters, repacking bearings, and cleaning electrical connectors to prevent future issues. Please contact us for all your Jeep and 4x4 needs.

Are you experiencing the notorious 3.6L tick issue? This problem can be attributed to failing rocker arms or failed lifters. The longer you delay addressing this issue, the more extensive the damage will be to the cams and the entire engine. A customer recently presented with this issue, which had been ongoing for approximately two weeks prior to bringing it to our attention. Upon inspection, we discovered a couple of faulty rocker arms and lifters. To prevent any further complications, we replaced all of them. While we were addressing this issue, we also replaced the problematic plastic oil cooler/filter housing with an upgraded all-aluminum component. Please contact us for all your Jeep and 4x4 needs.

Our team successfully restored an early WWII era GPW frame, which had suffered extensive damage, including a completely rusted bottom section. After investing considerable time in cutting, fabrication, and welding, we were able to revive this frame. One notable feature of the GPW is the Ford Signature F stamped on various components, including bolts and washers. At Big Muddy Boyz Offroad Customs, we provide an array of services, including daily maintenance, full restoration, and custom builds. For assistance with your Jeep and 4x4 needs, please contact us at 618-417-5414. Big Muddy Boyz Offroad Customs
A special thanks goes out to Jerry Rankin and his shop. He is restoring the tub for this project.

The customer brought this Gladiator back to us for a complimentary 500-mile break-in inspection after we installed new gears a couple of weeks ago. This inspection is provided free of charge with all our gear and lift kit installations to guarantee proper fitment and break-in. During the inspection, the customer mentioned experiencing death wobble, prompting us to conduct a comprehensive inspection of the steering and suspension systems. We identified issues with the track bar and a tie rod end and are addressing these problems while the Jeep is in our shop. Please contact us at 618-417-5414 for all your Jeep and 4x4 requirements.
