Frequently Asked Questions About Semi-Truck New Products

What truck models and years are compatible with your new bumpers and accessories?

Our new products are designed for popular models including Peterbilt 379, 389, and 359; Kenworth W900, T800, and T600; Freightliner Classic and Coronado; and Western Star 4900. Most items fit trucks from 1990 to current model years, but exact compatibility varies by product. Each product page includes a detailed fitment guide with specific year ranges and model numbers. If you're unsure about compatibility, call our tech support at 1-888-875-7787 with your truck's VIN for verification.

What materials are used in your bumpers, and how thick is the steel?

Our aftermarket bumpers are typically made from either 16-gauge (.0598") or 14-gauge (.0747") cold-rolled steel, depending on the specific model. Premium options feature 304 stainless steel with 16-gauge construction. All bumpers include reinforced mounting brackets and use automotive-grade primers and finishes. Chrome bumpers feature triple-plated nickel-chrome over copper base for maximum durability and shine retention.

Do I need special tools or professional installation for these products?

Most bumper installations require basic hand tools including socket sets (typically 3/4" and 7/8"), wrenches, and a drill with metal bits for some applications. Installation typically takes 2-4 hours for experienced mechanics. While many owner-operators successfully install these themselves, some products like air ride suspensions or complex light bars may benefit from professional installation. Each product includes detailed instructions, and we offer phone support for DIY installers.

What finish options are available, and how do they hold up to road conditions?

We offer chrome-plated, polished stainless steel, painted, and powder-coated finishes. Chrome bumpers feature triple-plating for corrosion resistance but require regular polishing in salt-belt states. Stainless steel options need less maintenance but show fingerprints more easily. Powder-coated finishes come in black, white, and custom colors, offering excellent chip resistance. All finishes are tested for UV resistance and road chemical exposure.

What's your return policy if a product doesn't fit or meet expectations?

We offer a 30-day return policy on most new products in original packaging with no installation marks. Custom-ordered or modified items are non-returnable. Shipping costs for returns are the customer's responsibility unless we shipped the wrong item. Before ordering, we recommend calling to confirm fitment to avoid return shipping costs. Defective items are covered under manufacturer warranties ranging from 90 days to 3 years depending on the product.
