Question:

Will this fit in a bulletproof adjustable hitch?

Thanks for letting us help Mike. The Lock N Roll Articulating Hitch - Adjustable Channel Mount # 336VS503 will fit inside the adjustable channel of the heavy duty BulletProof Hitches 2-Ball Mounts like the # HD258 you purchased previously. The # HD258 uses a 3" wide channel with adjustment holes spaced 2" apart on center, which matches the mounting dimensions required by the # 336VS503.

I assume you are referring to the ball mount you already have, but not every BulletProof adjustable ball mount uses this same channel size. Some of their lighter-duty models, such as # BPH89MR, use a narrower channel and would not be compatible with the Lock N Roll mount. Since you already have the # HD258, though, you'll be able to mount the # 336VS503 directly into its adjustable channel.

Does your trailer already have a Lock N Roll articulating coupler, or are you planning to convert the trailer side as well?
