Frequently Asked Questions About GMC General Truck Front Axle Air Ride Kits

What GMC General model years are compatible with these front axle air ride kits?

Our front axle air ride kits are designed specifically for GMC General trucks manufactured between 1977 and 1987. These kits are engineered to fit the standard front axle configurations found in GMC General models including the 7000, 8000, and 9000 series. Before ordering, verify your truck's specific axle model number (typically found on the axle tag) to ensure proper fitment. If your GMC General has been modified with aftermarket axles, please contact our technical support team for compatibility verification.

How difficult is the installation process, and what tools are required?

Installation typically takes 6-8 hours for experienced mechanics and requires standard shop tools including air tools, jack stands rated for heavy trucks, and basic hand tools. The most challenging aspect reported by customers is properly aligning the air bags during installation and ensuring adequate clearance from moving components. You'll need to drill mounting holes for the brackets and route air lines safely away from heat sources. Many customers recommend having a helper during installation, particularly when positioning the heavy air spring assemblies. Professional installation is recommended if you're not comfortable working with air brake systems or heavy truck suspensions.

What weight capacity and ride height adjustment range do these kits offer?

Our GMC General front axle air ride kits typically support between 12,000 to 20,000 pounds per axle, depending on the specific kit model. The air springs provide approximately 4-6 inches of ride height adjustment when properly installed. Operating pressure ranges from 5 PSI (minimum to prevent damage) to 100 PSI maximum. Most drivers find their optimal ride quality between 60-80 PSI for loaded conditions. Always refer to your specific kit's documentation for exact weight ratings and pressure specifications.

What components are included in the complete kit, and what additional parts might I need?

Each complete kit includes heavy-duty air springs, upper and lower mounting brackets, all necessary hardware (Grade 8 bolts, washers, and lock nuts), detailed installation instructions, and inflation valves. However, you'll need to purchase separately: air lines (typically 1/2" DOT approved), fittings specific to your air system, and a control system (manual paddle valves or electronic management). Some customers also upgrade to stainless steel air lines for increased durability. An on-board air compressor system is required if your truck doesn't already have one.

How do these air ride kits perform in extreme weather conditions and what maintenance is required?

The air springs in our kits are constructed from multi-ply rubber and cord reinforced with steel beading, rated for temperatures from -40?F to 180?F. In freezing conditions, ensure your air system has proper moisture removal to prevent ice formation in air lines. Regular maintenance includes monthly visual inspections for air leaks, checking air spring condition for cracks or excessive wear, and maintaining proper operating pressure. Most customers report 100,000-150,000 miles of service life with proper maintenance. Keep mounting hardware torqued to specification and replace air springs at the first sign of weather cracking or cord exposure.
