Frequently Asked Questions About Mack CX Truck Cab, Sleeper & Cowl Panels

What years and models of Mack CX trucks are these panels compatible with?

Our Mack CX cab, sleeper, and cowl panels are designed to fit Mack CX Vision models from 2000-2015. However, there were minor design changes throughout production years. Panels for 2000-2005 models differ slightly from 2006-2015 versions, particularly around mounting hole locations and edge contours. Always verify your specific truck's VIN and production year before ordering to ensure proper fitment.

Are these panels made from the same material as OEM parts, and how thick are they?

Most aftermarket panels are constructed from 16-18 gauge steel, matching OEM specifications. Premium options feature galvanized steel with e-coating for superior rust resistance. Fiberglass panels are also available for weight reduction, though they require different installation techniques. Steel panels typically weigh 15-25 pounds depending on size, while fiberglass alternatives weigh approximately 40% less.

What tools and expertise are needed for installation?

Installation requires basic body work tools including a drill with metal bits, rivet gun, panel adhesive, and seam sealer. Most panels require trimming for exact fit. Professional installation typically takes 3-5 hours per panel. Common challenges include aligning mounting holes (some drilling required), dealing with rust on mounting surfaces, and ensuring proper door-to-cab gaps. We recommend having a helper for larger sleeper panels due to their size and weight.

Do these panels come primed or painted, and what prep work is required?

Panels are available in three finishes: bare metal, primed, and painted. Bare metal panels require immediate rust prevention treatment. Primed panels come with a gray primer coat ready for paint but should be scuffed and cleaned before topcoat application. Pre-painted panels are color-matched to common Mack colors but may require blending at installation points. All panels should be test-fitted before final painting.

What's the typical lifespan of these replacement panels compared to factory parts?

Quality aftermarket panels last 10-15 years with proper installation and maintenance. Galvanized and e-coated panels can extend this to 15-20 years. Key factors affecting longevity include proper rust treatment of mounting areas, use of quality seam sealer, and regular washing to prevent road salt accumulation. Fiberglass panels won't rust but may crack from impact or stress, typically lasting 12-18 years in normal use.
