Frequently Asked Questions

The JNR Fast Up Kit has a tank with a pressure switch which allows no wait on the compressor because the air tank will already have stored air ready to use.

What is the difference between the 95c, 98c and 100c compressors?

The 95c will build a higher pressure than the 98c, the 98c will have a higher volume but less pressure than the 95c. The 100c compressor is the best of both worlds being the largest compressor of the three, putting out more volume and pressure than the 95c and the 98c.

Should I use 5/32″ airline or 1/4″ airline?

We recommend all kits and components use 5/32″ airline. This is due to the 1/4″ airline requiring more volume of air to fill, as well as being harder to route as cleanly as the 5/32″. Both have the same DOT pressure rating. Please review our Warranty Info before ordering 1/4″ components.

What shipping method does JNR use?

We use USPS priority shipping. Once your order has shipped it typically will arrive to you in 2-3 days in the United States. This includes weekends.

Why won’t my shocks stay aired up?

The most common problem on any air ride system is the dump valve. They tend to get debris caught in them which will cause the valve to not fully seat and cause air to escape. The dump valve is very easy to tear down and clean out. Here is a short video on how to do this. It is best to start with this step because it does not require you to pay to replace anything and is the most common cause for leaks. (Click here for the Dump Valve tear down video)
