Fiberglass fenders and bedsides are essential for off-road racing, but they provide great benefits for consumers like you and us as well. Adding fiberglass in place of factory panels can sometimes drop weight off your ride, and the enlarged wheel openings means you can fit a bigger tire without rubbing the body. If a fiberglass panel gets damaged, it can be repaired and replaced fairly easily. If you had something happen to your factory fenders or bedsides (read: You crashed), then fiberglass units are usually cheaper.
With this truck, we had two reasons to put fiberglass on: 1) We'd already done the front and we were going to do the bedsides next anyway, and 2) During that transitional period, some stupid BMW owner ran a stop sign and decided that the truck would look better with a crushed bedside. This sped up the process of the bedsides install.
We were originally hesitant about fiberglass bedsides because we weren't sure what we would have to change on the truck to install them. This isn't a race truck, after all; this is a daily driver. Could we keep the inside of our bed? How about the tailgate and the stock rear bumper, or the taillights even? Upon recommendation from Glassworks Unlimited, we called Desolate Motorsports in Whittier, California, to get some answers. Desolate invited us down to watch the bedsides go on in around four hours, keeping all other factory equipment. A crew of two guys worked on this and they had done it many times before, so count on using the better part of a weekend if you try this at home.
