Description

These FiberwerX bedsides are crafted from composite material, offering a 4.5-inch bulge and a 2.5-inch rise to provide an aggressive stance for your 1999-2006 Chevrolet Silverado or GMC Sierra. Designed specifically for the 6.5ft bed, they seamlessly integrate with your factory tailgate and tail lights. The package includes both driver and passenger side bedsides, and a fuel door cutout is also included for a complete aesthetic. Available in both fiberglass and carbon fiber options, these bedsides are manufactured using wet and vacuum bagging techniques. Note that minor cosmetic imperfections like pin-point sized air pockets may be present in carbon fiber variants due to the manufacturing process, and are generally only visible at extreme angles. Similarly, modular mold construction can result in slight seams on edges, which FiberwerX addresses with a "ghosted" effect using black gel coat. Professional installation is recommended for optimal results. The manufacturer advises testing fitment before final installation and recommends surface preparation and primer before painting. All necessary mounting hardware and detailed installation instructions are included with your purchase.
