Frequently Asked Questions About GMC General Truck Clamps, Brackets & Mounting

Will these mounting brackets fit my specific GMC General model year?

Most of our GMC General mounting brackets and clamps are designed to fit models from 1977-1987. However, there can be variations between early and late production years. We recommend checking the product description for specific year ranges or contacting our support team with your VIN number to ensure proper fitment. Some universal brackets may require minor modifications for certain model years.

What grade of steel are these brackets made from, and will they rust?

Our GMC General brackets are typically manufactured from either cold-rolled steel with zinc plating or 304-grade stainless steel, depending on the specific product. Zinc-plated options provide good corrosion resistance for most applications, while stainless steel brackets offer superior rust protection for trucks exposed to road salt or coastal environments. Each product listing specifies the material and finish type.

Do I need to drill new holes or modify my frame to install these brackets?

Most of our brackets are designed as direct bolt-on replacements using existing mounting points on your GMC General. However, some universal brackets or custom applications may require drilling. Each product description clearly states whether drilling is required. We recommend having basic hand tools, including wrenches, sockets, and possibly a drill with metal bits if modifications are needed.

What weight capacity can these mounting brackets safely support?

Weight ratings vary significantly between bracket types. Light-duty brackets for accessories typically support 50-150 pounds, while heavy-duty frame brackets can handle 500+ pounds. Always check the specific weight rating listed in the product details and consider adding a safety margin of 25-30% below the maximum rating for optimal performance and longevity.

Are these brackets compatible with aftermarket accessories like light bars or toolboxes?

Many of our GMC General brackets feature universal mounting patterns that work with common aftermarket accessories. Look for brackets with multiple hole patterns or slotted mounting points for maximum versatility. For specific accessories, measure the mounting bolt pattern and compare it to the bracket specifications, or contact us with your accessory brand and model for compatibility confirmation.
