Key Similarities
From reviewing the above sections, you can likely already determine a few similarities between the two kits. For instance, they both work to complement the suspension system with load leveling. They both will reduce suspension sag which will improve truck driving performance. However, there are other key similarities that are worth noting. These include:
- Sway reduction: In addition to providing a better unloaded and loaded driving experience, and reducing rear sag during towing, both types of suspension kits are also designed to minimize sway.
- Ease of installation: While both are kits, both are also both revered for how simple they are to install. Timbren kits usually just require a socket wrench to install. You can learn more by watching a few Timbren installation videos. Air spring kits are a bit more difficult, as users first need to determine where to install them (i.e., leaf springs, axle, coil) and may also need to incorporate an on-board compressor to inflate it, however it's still manageable for a DIY'er.
Key Differences
One of the biggest, most notable differences between Timbren and air springs is the manner in how each adjusts to varying conditions and preferences. While air springs need to be kept at a minimum of 5 psi to protect the component, air can be added and subtracted based on driver preference. Hence, it’s a bit more customizable. Timbren, on the other hand, automatically adjusts to different loads and conditions. However, this point also segues to another key difference between the two suspension kits: degree of maintenance. With Timbren, there’s practically no maintenance since adjustments are automatic. But with air springs, maintenance must be performed occasionally to ensure the component doesn’t dip below 5 psi. What’s more is that since the air springs work with air, there’s the potential for the component to leak.
Here’s a look at some other key differences:
- Cost: Cost varies based on the type of vehicle that you drive, but generally speaking, Timbren kits are more affordable than air spring kits.
- Smoother loaded ride: Though both kits are designed to improve ride quality in both loaded and unloaded situations, air springs are considered to offer a better loaded ride. This is largely attributed to the fact that air springs are more customizable than Timbren via their ability to be inflated and deflated.
- Maintenance: Timbren kits are the maintenance-free option and once they are installed you’re done. While maintaining air bags is not difficult, it still has to be done. They are like a tire in that you have to have a minimum air pressure in them at all times. The number one reason for failure that we come across is air bags that are damaged because the vehicle was driven without any air in the springs.
