Mack CX Truck Chrome Stacks & Tops

Frequently Asked Questions About Mack CX Truck Chrome Stacks & Tops

Will these chrome stacks fit my specific Mack CX model year?

Our chrome stacks are designed to fit Mack CX models from 2012-2020. However, slight variations exist between early and late production years. For 2012-2014 models, you may need additional mounting brackets (sold separately). Always verify your truck's VIN and production date before ordering. If you're unsure, contact our support team with your truck details for exact fitment confirmation.

What's the difference between 304 and 316L stainless steel options?

304 stainless steel stacks offer excellent corrosion resistance and chrome finish for standard applications. They're ideal for most highway and regional hauling. 316L stainless steel contains molybdenum, providing superior resistance to road salt, chemicals, and coastal environments. While 316L costs 20-30% more, it's recommended for trucks operating in harsh winter conditions or near saltwater. Both grades maintain their mirror finish with proper maintenance.

Can I install these stacks myself, or do I need professional help?

Installation typically takes 2-4 hours with basic tools including socket wrenches, drill, and measuring tape. Most customers successfully complete DIY installation using our detailed instructions. Key challenges include proper alignment and securing the weight (stacks can weigh 40-80 lbs each). You'll need a helper for lifting and positioning. Professional installation runs $200-400 but ensures proper mounting and exhaust seal integrity.

How do curved vs. straight stacks affect performance and appearance?

Straight stacks provide a classic, aggressive look and slightly better exhaust flow, ideal for highway hauling. Curved (or mitered) stacks direct exhaust away from the cab, reducing soot on trailers and improving driver comfort. They're preferred for vocational trucks or frequent stop-and-go operations. Both styles offer identical durability. Choose based on your aesthetic preference and primary hauling application.

What maintenance is required to keep the chrome finish looking new?

Chrome stacks require cleaning every 2-4 weeks to prevent discoloration from exhaust residue. Use dedicated chrome polish and microfiber cloths - avoid abrasive cleaners. For stubborn buildup, apply aluminum polish with 0000 steel wool, working in circular motions. Winter road salt demands weekly cleaning to prevent pitting. Budget 15-20 minutes per stack for thorough maintenance. Neglected stacks may develop permanent heat discoloration within 3-6 months.
