Frequently Asked Questions About Mack CV/GU Truck Clamps, Brackets & Mounting

Will these clamps and brackets fit my specific Mack CV713 or Granite model year?

Most clamps and brackets for Mack CV and GU series trucks are designed to fit models from 2000 onwards, including CV713, Granite, and Vision models. However, there can be variations between pre-2004 and post-2004 models, particularly in exhaust stack mounting points and mirror bracket configurations. Always verify the specific year range listed for each product, and when in doubt, provide your VIN number to our customer service team for exact fitment confirmation.

What material are these brackets made from, and how do they hold up against rust and road salt?

The majority of our Mack mounting brackets are constructed from heavy-duty steel with either powder coating or chrome plating for corrosion resistance. Steel brackets typically feature 3/16" to 1/4" thickness for structural integrity. For maximum durability in harsh conditions, look for stainless steel options which offer superior rust resistance without requiring additional coating. Chrome-plated brackets provide good protection but may require periodic maintenance in high-salt environments.

Do I need to drill any holes for installation, or do these use existing mounting points?

Most brackets and clamps are designed as direct bolt-on replacements using existing factory mounting holes. Mirror brackets, exhaust clamps, and air cleaner brackets typically require no drilling. However, some auxiliary light bars and custom accessory mounts may require drilling 1-2 additional holes. Each product description specifies whether drilling is required, and installation hardware is usually included with brackets that use existing mount points.

What size exhaust stacks and pipes do these clamps accommodate?

Standard exhaust clamps for Mack CV/GU trucks typically accommodate 5-inch and 6-inch diameter stacks, with some universal adjustable clamps fitting 4-inch to 7-inch pipes. Band-style clamps offer the most flexibility, while saddle clamps provide more rigid mounting. Always measure your exhaust stack diameter before ordering, as Mack trucks can be equipped with various exhaust configurations from the factory or through aftermarket modifications.

Are the mounting brackets strong enough to support heavy accessories like toolboxes or spare tire carriers?

Our heavy-duty mounting brackets are rated for specific weight capacities, typically ranging from 50 to 300 pounds depending on the application. Toolbox brackets and spare tire carriers are reinforced with gussets and use grade 8 mounting hardware. For accessories over 100 pounds, we recommend brackets with multiple mounting points to distribute weight evenly. Always check the weight rating listed in the product specifications and ensure your frame can support the additional load.
