Peterbilt 352 Front Axle Air Ride Kits

Frequently Asked Questions About Peterbilt 352 Front Axle Air Ride Kits

Will these air ride kits fit my specific year Peterbilt 352?

Our front axle air ride kits are designed to fit Peterbilt 352 models from 1969 through 1980. However, compatibility can vary based on your truck's specific configuration, including axle type (Rockwell, Eaton, or Dana), spring spacing, and whether you have a set-back or set-forward front axle. We recommend checking your existing spring measurements and axle model before ordering, or contact our technical support team with your OEM for verification.

What tools and experience level are needed for installation?

Installation typically requires intermediate to advanced mechanical skills and takes 4-6 hours. Essential tools include a floor jack rated for commercial trucks, jack stands, air tools, torque wrench (capable of 450 ft-lbs), and basic hand tools. You'll need to safely support the front axle while removing leaf springs and installing the air bags. Many customers report that having a helper makes the job significantly easier, especially when aligning brackets. Professional installation is recommended if you're not comfortable working with heavy truck suspension components.

What's included in the complete kit and what additional parts might I need?

Our complete kits include air bags, upper and lower mounting brackets, all necessary hardware, air lines, fittings, and detailed instructions. However, you'll need to purchase separately: an air compressor system (if your truck doesn't have one), air valves or electronic controls for ride height adjustment, and potentially new U-bolts if your existing ones are worn or the wrong length. Some installations may also require minor frame modifications or reinforcement plates depending on your truck's condition.

How much weight can these air ride systems support?

Most of our Peterbilt 352 front axle air ride kits are rated between 10,000 to 14,000 pounds, depending on the specific model. This rating should exceed your front axle weight rating (FAWR) found on your door jamb sticker. For heavy-haul applications or trucks with specialized front-end equipment, we offer heavy-duty options rated up to 20,000 pounds. Always verify that the kit's weight rating matches or exceeds your truck's front axle loading requirements.

What maintenance is required and how long do the air bags typically last?

Air bags generally last 80,000 to 100,000 miles with proper maintenance, though we've seen them go much longer with good care. Regular maintenance includes checking air pressure weekly, inspecting for leaks or abrasion monthly, and keeping the bags clean from road chemicals and debris. The mounting hardware should be torque-checked every 10,000 miles. Common failure points are usually from rubbing against components or damage from road debris rather than normal wear. Replacement air bags are readily available and can typically be changed in under an hour per side.
