they should be, cross reference the part numbers from partzilla, rocky mountain atv. partzilla is easier, just click on the make, model, year, then look through the parts list, find your swing arm, click on part number, then down on the lower right side, it will show you what all models that part fits .actually . looks like that part number is just for a warning label. not the swing arm.
that being said. will all TRX200D swing arms be interchangeable?
