Wheel Hardware -


What size wheel bolts do I need?

- Well, as you've probably learned, wheels vary is size depending on Make, Model, and even sometimes Year. The best way to know if to either measure a current bolt/back nut, or, If you don't have access to one, contacting us. 99.9% of US Made wheels run an M8x32MM bolt. Many rare Japanese wheels run an M6 size, some standard, some Torx. New Japanese wheels run either M7x30, M7x32 or M8x32MM, and most European wheels run an M7x24, M7x30 or M7x32.


I have two piece wheels, do you sell cosmetic bolts?

We currently only carry Work Wheel cosmetic bolts. 


Which Valve Stem size do I need?

If it's a non 90 Degree, more than likely an 11.3MM. 8.3MM is a dead size, that only a few older wheels run. However, if you're uncertain, you can measure the valve hole, or old valve. If you're running a 90 Degree, you may need a 1.8", or 2.8". Again, measure, or contact us directly. 


Do you carry Step Lips/Barrels?

We do not - we stopped supplying many sizes due to market production times. If you're in the need of any, please let us know and we can refer you to some of our close friends in the wheel business. 


Do you stock all your hardware?

We stock most of it. Due to certain sizes/finishes sitting on shelves, we have lightened our stock. However, we do accept custom orders on all hardware, whether stocked or not. If that's the case, shipping is a bit extra, and it takes about a week and a half to get out to you. 


How long until I receive my hardware?

Generally, if purchased before 2PM MST, it ships same day - USPS 2-3 Day Priority. 


Do you ship international?

We do - but not everywhere. Canada is flat rate $25 for small boxes, so a set of hardware. Everywhere depends on location. 


Do you offer shipping insurance?

We only offer the standard $50 that USPS provides. If you would like additional insurance, please contact us prior to your order. We are not responsible for package damages. 


I am looking for hard to find wheel parts, can you help?

WE CAN TRY! We have a few awesome friends in the business, that are masters at sourcing rare wheel parts. We can't promise, but we can try. Just shoot us an email. 



Air Suspension -

 Is air suspension reliable?

When properly installed, air suspension can provide many years of trouble free service. Today’s technology and materials have allowed even OEM manufactures to offer their cars with air suspension options, while the trucking industry rides millions of miles every year almost exclusively on air. ALP in particular use similar products and technology to build their suspension kits. In addition, Air Lift torture tests all of its major components in-house on industry exclusive test equipment to ensure every aspect of reliability. And before a new kit hits the streets, they take it to the track and show it no mercy, allowing them to pinpoint any weaknesses. This comprehensive approach along with their unlimited 1 year warranty means you are getting the best made air suspension kits in the industry!


Can air suspension be used in the winter?

Most certainly yes! While winter does provide some unique challenges to driving, some simple maintenance on your air system can make cold climate motoring a non-event. We do recommend adding a capful of "Anti Air Brake Freeze" to your tank, to ensure moisture does not freeze over in freezing temps. 


What kind of maintenance is recommended for air suspension?

Overall, the only maintenance is to regularly drain the air tank to reduce the amount of water circulating through the system. ALP offers in-line water traps that can aide in this activity, while also significantly reducing the amount of water that gets in the system in the first place. In any case, draining the system once a month is a good rule of thumb and only takes a minute. For those of us in the northern climates, keeping your system dry is key to trouble-free running in the winter.


What is the difference between Slam Series and Performance Series?

Quite a lot! Learn all the differences here.


What is difference between analog, manual and digital air management?

Analog refers to the “old school” systems that use a switch box in the cabin that sends high current DC signal to electrically operated solenoid valves that control air entering and exiting the air springs. The amount of air pressure is controlled by the amount of time the user activates the switch. This technology was/is often found on mini trucks and hot rods because the large valves allow a large volume of air to move quickly.


Manual refers to a system that incorporates four cockpit mounted “paddle valves” that mechanically switch air flow from the tank in-to or out-of the air springs. This cost-effective system has very simple electrical connections, and is the most lightweight of the three types. It also includes two dual-needle air pressure gauges to monitor and set pressures. If simplicity and low cost is high on your list of requirements, this is your system.

Digital management brings to the game a whole level of sophistication and features. As the name suggests, there is an ECU that uses digital intelligence in the form of an algorithm to quickly and accurately move your suspension to the desired setting with no driver involvement besides pressing a button. Our Autopilot V2 system includes a compact manifold unit that contains the ECU, all the valves, and pressure sensors that monitor and activate the suspension, along with an OEM level wiring harness that only requires 3 wires to be connected to the vehicle. The interface for this hardware is a cockpit mounted controller that provides 8 unique user programmable presets. For the most convenience and flexibility, this is the system to have.


 What is the difference between air line sizes?

In the automotive aftermarket, there are 3 common size air lines: 1/4”, 3/8”, 1/2”. The most commonly used size tends to be 1/4” because it is the easiest to rout through the vehicle. Some people like the car to move from one position to the next faster than 1/4” can do (based on the flow rate and air spring volume/pressure requirements) so they tend to choose 3/8”. The crowd that likes 1/2” will choose that size because they want the body to spring up very quickly when a valve is activated. Installing ½” lines can be the equivalent of wrestling an anaconda…


What is a water trap and should I buy one?

A water trap, as the name suggests, is a device that traps water and keeps it from circulating around the air system. Where does the water come from you ask? If you remember your science class in school, air contains a lot of evaporated water, especially on humid days. This water gets squeezed out of the air when it gets compressed into the tank by the compressor. Adding a water trap helps keep this water from entering the manifold where, in winter, it can potentially cause freezing. And if you have a steel air tank, then you can reduce the tendency of the tank to rust on the inside by keeping the water out. Bottom line: a water trap is a good investment for keeping your system dry and functioning in all seasons.
