Custom 4x4 Modifications in Mareeba

Custom 4WDs need more than just accessories. That is why we offer complete build solutions, including GVM upgrades to increase your legal carrying capacity and suspension modifications to improve ride, handling and weight distribution. Whether you need to haul gear, tow a van or handle serious tracks, we design and install systems that perform. We also provide diff correction and axle conversions, especially for modified LandCruisers, so your geometry and drivability stay on point even after a lift.

Every project starts with a proper consultation, and every build is done in-house using parts and methods we trust. No guesswork, no generic setups. If your 4x4 needs more than a tune or bolt-on kit, talk to us about a full custom solution.
