INSTALL INSTRUCTIONS: BEDSIDES
All of our products are fairly easy to install. You will need a few hand tools and a few hours of time, depending on the products you have purchased. Also, you will reuse most of your stock hardware during this installation—it is typical to have a few screws and bolts left over, however. Advanced Fiberglass Concepts LLC does recommend that a professional install for a seamless fit install these products.
Tools required for most installs:
Although this is not necessary, we always recommend removing the bed to make the process easier
Step 1: Remove the taillights, as well as the bumper.
Step 2: Use a spot weld cutter to remove the factory bedside spot welds, which are located around the bedside.
Step 3: Once the stock bedsides have been removed, the inner bed structure will be showing and then it is time to mount our fiberglass bedsides. Best way to start, is by hanging the new fiberglass bedside over the bed rail.
Step 4: Align the fiberglass bedsides with all the bodylines on the cab and the taillights. You may have to sand or trim off the inner bed or fiberglass to get it into the correct position.
Step 5: Once you are happy with the alignment, it is time to bolt down the bedsides. We recommend our customers to use 4-6 evenly spaced bolts along the inner bed rail, one between the cab and the bed, and 1-2 bolts around the tail light area. Drill holes out with a 3/8 drill bit—the reason for this is so you can move the bedside back and forth to align the gap. Once you have the gaps spaced, tighten down the bolts. Do not over tighten! The fiberglass bedside will make sounds like it is cracking—this is common as it is fiberglass, so do not worry.
Step 6: Now as the last step, it is important to secure the front and rear portion of the wheel well. There are supports in all trucks, although you can modify your old mounts to work with the fiberglass bedsides or you can fabricate your own custom mounts.
You will need to be patient to get a good fit. You may need to sand some of the bedside down for desired fitment. This is because fiberglass bedsides are thicker than steel.
Please keep in mind—although all of our products are made from factory steel fenders, hoods, and bedsides, there is a difference in fit because of the thickness of the fiberglass compared to steel. Therefore, please be patient when you start this job.
If you need further assistance with this installation, feel free to call us—one of our techs will be more than happy to help you.
These instructions are useful for all bedsides sold by Advanced Fiberglass Concepts — therefore some of the steps may not be needed or should be slightly altered to suit your particular vehicle and product needs.
We do our best to have as much inventory as possible. However, if they are not in stock, then our lead-times are normally 2-4 weeks from order date. Please contact us through live-chat, email, or phone to check inventory and current lead-times.
All our products are shipped through LTL Freight carriers. Shipping prices are calculated in the checkout area. Our products can get expensive to ship because we ship all our products with premium LTL Freight carriers to ensure they are not damaged (All orders are insured in case of potential shipping damages). Other factors that control the shipping cost are the size of the package, weight, overall destination, and nature of the product (Fiberglass), which all play a large role in shipping costs. To help cut down the shipping cost, ship to a commercial address.
The panels are made from fiberglass (or carbon fiber if requested at an additional cost). We use a proprietary blend of polyester resin which is paired with our fiberglass mat and cloth. This combination of resin and fabric provides the strength and flexibility to make our body panels a superior product.
Products come semi-gloss white unless requested in a specific gelcoat color. We do not offer color matching services. All gelcoat colors are generic colors and will not be an exact color match. Any body shop in your local area can color match our products. All products require prep work for paint.
