NA/NB Hard Dog Roll bar trim kit

Hard Dog roll bars are great in all sorts of ways, but it’s tough to cut the carpet for the rear supports perfectly – it almost always looks a bit rough. Avoid that problem altogether with this trim kit. This kit has 3D-printed collars that cover the cut carpet, giving a clean and professional look. The outside diameter is 3″, so any cuts that fall outside that size will still be visible. 

The two-piece interlocking design is easy to install, and the nylon-tipped stainless steel set screws hold them securely in place without marring your powder coat. 

Be sure to choose the correct version for your roll bar! Not sure what style you have? As long as it’s a Hard Dog roll bar, 1.5″ diameter tubing is a Sport bar and 1.75″ tubing is a Hard Core bar. The Hard Core trim kit is the same for NA and NB bars, but the Sport kit is different – if your Sport rear supports are straight, it’s an NA, if they have a bend, it’s an NB. Bear in mind that there are lots of NB Sport bars in NAs, as those are required if your soft top has a glass window. For the sake of simplicity, we sell the NB Sport bar as a 1990-05, as it will fit that entire year range great. 

As long as the tubing diameter matches, these could fit other brand roll bars, although the trim may or may not be parallel to the package shelf (i.e., the rear support angle on your bar may or may not match the Hard Dog bars). The carpet and dark color gives you a bit of leeway, but we can’t guarantee perfect fitment.
