Frequently Asked Questions About Mack CH/CHN/CHU Truck Front Axle Air Ride Kits

Will these air ride kits fit my specific Mack CH model year, and what are the weight capacity ratings?

Our front axle air ride kits are designed to fit Mack CH, CHN, and CHU models from 1988 through 2007. Each kit is engineered to handle front axle loads between 12,000 to 20,000 pounds, depending on the specific kit model you choose. Before ordering, verify your truck's front GAWR (Gross Axle Weight Rating) on the driver's door jamb sticker to ensure you select the appropriate capacity kit. Note that some early 1988-1990 models may require additional bracket modifications.

How difficult is the installation, and what tools or professional help will I need?

Installation typically takes 6-8 hours for an experienced mechanic or 10-12 hours for a skilled DIYer. You'll need standard shop tools including impact wrenches, jack stands rated for commercial trucks, and ideally a vehicle lift. The most challenging aspects are removing the existing leaf springs and aligning the new air spring mounts. Many customers report needing to slightly enlarge existing frame holes or drill new ones for proper fitment. We strongly recommend professional installation if you're not experienced with heavy truck suspension work, as improper installation can affect ride quality and safety.

What's included in the complete kit, and will I need to purchase additional components?

Each complete kit includes air springs, upper and lower mounting brackets, air line fittings, detailed instructions, and all necessary hardware. However, you will need to purchase separately: an air management system (manual paddle valves or electronic controller), air lines, a minimum 5-gallon air tank if your truck doesn't have auxiliary air capacity, and height control valves if you want automatic leveling. Budget an additional $400-800 for these components depending on whether you choose manual or electronic controls.

How much will this actually improve my ride quality, and are there any downsides?

Customers consistently report a 60-70% improvement in ride quality, particularly noticeable on rough roads and expansion joints. The air ride significantly reduces cab shake and driver fatigue on long hauls. However, be aware that air systems require more maintenance than leaf springs - expect to inspect air bags every 50,000 miles and replace them every 200,000-300,000 miles depending on use. In extremely cold climates (below -20?F), you may experience slower response times until the system warms up. Some drivers also note a slight increase in ride height (1-2 inches) which may affect fifth wheel settings.

Which brand should I choose, and what's the real difference in quality between price points?

We carry three main quality tiers: economy, standard, and premium. Economy kits ($1,200-1,500) use imported air springs that typically last 150,000-200,000 miles. Standard kits ($1,800-2,200) feature Firestone or Continental air springs rated for 250,000+ miles. Premium kits ($2,500-3,000) include Hendrickson or Link air springs with reinforced mounting brackets and lifetime warranty on metal components. The main differences are air spring longevity, bracket thickness (economy uses 3/8" steel vs. premium's 1/2" steel), and included features like integrated shock absorbers on premium models. For trucks running 100,000+ miles annually, we recommend investing in standard or premium kits for better long-term value.
