Our stainless steel rear light bars have a number of different names - t-bars, rear bumpers, one-piece mudflap hangers, and probably more that we've never heard. In any case, they're a great alternative to two-piece mudflap hangers and rear center panels. The solid construction looks wicked on the end of your frame, especially with a T-bar, which has mudflap hangers and a rear center panel built together in one piece. Some styles have light holes, some have a LOT of light holes, and some are blank. It's a great way to customize your lighting setup and express your truck's unique personality.
