If you are building an XJ, get comfortable with cutting sheetmetal. Up front you can gain 2 inches of clearance and out back you can get about 1-inch before getting into the pinch seam. Cutting the pinch seam isn’t the end of the world, as long as you are comfortable with welding sheetmetal back together. Or, cut the spot welds and fold the seams inward. A set of four rear TJ flares will work well with a lower-than-pinch-seam trim job. Shown here is an Iceland Off-Road fiberglass flare with a pinch-trim-and-weld job. Rusty’s Off-Road also offers flexible flares that can work with just about any trim job.
