Our product listing is for the GWM Tank 300 2023 onwards, so buyers with a Tank 500 or a different Tank model should not assume compatibility. Side ladder fitment depends on the body shape, side mounting points, panel clearance and existing exterior accessories. Before buying GWM aftermarket car parts in Melbourne, confirm your exact model, year and mounting area first.

We recommend professional installation. A side-mounted ladder is not just a cosmetic trim piece because it needs secure mounting, correct alignment and proper clearance against the body panel. Poor installation can cause movement, panel contact, uneven fitment or long-term stress around the mounting points. If you want the ladder to look clean and function properly, professional fitting is the smarter choice.

For the best check, send your GWM model, year, current exterior setup, wheel specs if relevant, and clear photos of the area where the part will be installed. This is especially useful for Tank 300 side ladders and Tank 300 / Tank 500 off-road wheels, where model, mounting points, clearance and wheel specifications matter before buying GWM car accessories in Melbourne.
