Got rust or damage on the lower corners of your 2014-2018 Chevy Silverado or GMC Sierra Crew Cab? This Elitewill kit is the fix. It's a set of FOUR steel repair panels: both left and right rocker panel covers AND both left and right cab corner covers.
These are 'slip-on' or 'overlay' panels. You don't have to cut out all the old, rusty metal. Instead, you trim the bad areas, treat any remaining rust, and then these heavy-gauge steel panels slide over the top and weld or rivet into place. A huge time-saver! They have a dark green zinc coating for corrosion resistance.
Part number EW-C1484. Comes with a 10-year warranty. A professional-looking repair for a fraction of the body shop cost. For DIY welders or experienced bodywork folks.
