Cons: Installation is very labor-intensive and often requires professional skills.; Some owners report that the shocks wear out faster than expected.
6. Suncore Industries Air Spring Conversion Kit: Budget Friendly
For owner-operators on a tight budget, the Suncore Industries kit offers a way to experience air ride benefits without breaking the bank. We compared its specifications to more expensive kits and found that while the capacity is lower, it still provides a noticeable improvement in comfort for lighter loads. Owner feedback indicates that the kit is a good entry point, especially for those who do not haul heavy loads regularly.
However, the air springs are made from a less durable rubber compound, and some users reported leaks after a year or two. The kit also lacks the advanced leveling features of higher-end systems. If you carry maximum loads or drive in harsh conditions, this kit may not hold up. It is best for light-duty regional haulers who want a cost-effective upgrade and are prepared for eventual replacement.

Frequently Asked Questions
What is the difference between air helper springs and a full air ride conversion kit?
Air helper springs, like the Firestone Ride-Rite, are add-on systems that work with your existing leaf spring suspension to provide extra load support and leveling. They do not replace the factory suspension. Full air ride conversion kits, such as the Kelderman or RideTech, remove the leaf springs entirely and replace them with air springs and shocks, offering a much smoother ride and adjustable ride height. Helper springs are easier to install and less expensive, but full conversions provide superior comfort and control.
Do I need an onboard air compressor to use an air ride suspension kit?
Most air spring kits require an external air source to inflate the springs. Some kits include a compressor and controller, while others require you to purchase them separately. If you already have an air system for other accessories, you may be able to tap into it. For kits like the Timbren SES, no air is needed because they use rubber springs instead. Always check the kit’s requirements before purchasing.
How long do air springs typically last on a semi truck?
Based on owner feedback and industry reports, air springs from reputable brands can last anywhere from 3 to 7 years depending on usage, load conditions, and maintenance. Factors that reduce lifespan include exposure to road salt, ozone, and frequent overloading. Regular inspection for leaks, cracks, and proper alignment can extend their life. Kits with higher build quality, like Stemco, tend to last longer in severe service.
Can I install an air ride suspension kit myself?
Helper spring kits are often designed for DIY installation with basic tools and mechanical knowledge. However, full conversion kits usually require welding, cutting, and significant mechanical expertise. Many owners choose to have a professional shop install them. We recommend assessing your skill level and reading the installation manual before starting. Improper installation can lead to safety issues and void warranties.
Will an air ride suspension kit improve fuel economy?
While not a primary benefit, an air ride suspension can contribute to improved fuel economy by maintaining proper ride height and reducing drag. When the truck is level, aerodynamics are optimized, and tire wear is more even, which can reduce rolling resistance. However, the effect is usually marginal (1-3% improvement) and depends on driving habits and load conditions. The main benefits are comfort, cargo protection, and chassis longevity.
