Frequently Asked Questions About GMC General Truck Parts

What years and models of GMC General trucks do your parts fit?

Our GMC General truck parts are designed to fit models from 1977 through 1990. This includes the GMC General series trucks such as the Brigadier, Astro, and other heavy-duty commercial models. Always verify your specific model year and OEM prefix before ordering, as some parts may have mid-year production changes. If you're unsure about compatibility, contact our support team with your truck's OEM number for exact fitment verification.

Are your GMC General bumpers made from chrome-plated steel or stainless steel?

We offer both chrome-plated steel and polished stainless steel options for GMC General bumpers. Chrome-plated steel bumpers provide an authentic OEM appearance at a lower cost but require regular maintenance to prevent rust. Our 304-grade stainless steel bumpers offer superior corrosion resistance and durability, making them ideal for trucks operating in harsh weather conditions or coastal areas. Each product listing clearly specifies the material type.

Do I need special tools or professional installation for GMC General bumpers?

Most GMC General bumper installations can be completed with standard tools including socket sets, wrenches, and a torque wrench. However, due to the weight of these commercial-grade bumpers (typically 50-100+ pounds), we strongly recommend having at least one assistant during installation. Some models may require minor drilling for mounting brackets. Professional installation typically takes 2-3 hours and may be worthwhile if you lack a proper lift or heavy-duty jack stands.

What's the difference between OEM-style and aftermarket GMC General parts?

OEM-style parts match the original factory specifications for fit and appearance, using the same mounting points and hardware locations. Aftermarket options may offer improvements like heavier gauge steel, additional chrome plating thickness, or enhanced mounting brackets. While aftermarket parts often provide better value and durability, always confirm they meet DOT requirements if your truck operates commercially. We clearly mark each product as OEM-replacement or aftermarket upgrade.

How do I determine the correct bumper width for my GMC General?

GMC General trucks came in various cab configurations and widths. Measure your existing bumper end-to-end, including any end caps or extensions. Standard widths are typically 86 inches, 96 inches, or 104 inches for different models. The measurement should be taken straight across the mounting surface, not following the bumper's curve. Our product descriptions include exact measurements and specify which cab styles each bumper fits. When in doubt, provide us with your truck's model designation (found on the door jamb sticker) for proper sizing.
