We build ours with \u003cstrong\u003e16-gauge wall thickness (about 1.5 mm \/ ~0.059\")\u003c\/strong\u003e, while a lot of the budget, price-point systems you see online are commonly built with \u003cstrong\u003ethinner wall tubing\u003c\/strong\u003e and lighter hardware to cut cost.\u003c\/p\u003e\n\u003cp\u003eHere’s why that matters in the real world:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1) More durable where trucks actually get abused\u003c\/strong\u003e\u003cbr\u003eThicker 16-gauge tubing is simply tougher.

On cheaper systems, thinner pipe and looser bend accuracy can show up as:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHangers that don’t line up clean\u003c\/li\u003e\n\u003cli\u003eTips that sit crooked\u003c\/li\u003e\n\u003cli\u003ePipes that sit too close and \u003cstrong\u003erattle\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eExtra “pre-load” stress because you’re forcing it into position\u003cbr\u003eThat pre-load stress is a major contributor to cracks later.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e3) Stronger weld areas and less warping\u003c\/strong\u003e\u003cbr\u003eWelding is where quality systems separate themselves.
