The Hallman Pro RX model comes with two springs. The light spring is pre-installed but it also comes with a standard spring that you can install instead of the light spring. If you want to swap the springs in your Pro RX model, please see section 6 of the Pro series instructions linked here.
The Pro model has the ability to raise turbocharger boost more than the Pro RX model. The Pro model can raise the boost substantially, to 30 psi or more. That does not mean it is safe to do so.
The Pro RX model with the light spring installed, unlike the Pro model, is designed to only provide a few extra PSI of boost over stock. It allows for very specific control of boost in finer increments. The Pro RX model is considered appropriate for low-boost setups.
You can ruin your engine if you do not do your research to determine what is safe and what is not safe. It varies tremendously depending on what car, what modifications have been done, etc. We will not tell you what is safe, that is your responsibility to research. It may sound harsh that we are not answering that for you, but after you research, you will understand why we state this. It is because there are many factors to consider.
If it is a coupler hose (like straight hose, hump hose, elbow hose, etc.) it is sold per piece, so the quantity you order will be the number of pieces. Each piece will be the standard length for that specific hose.
If you need a straight hose cut to a different length than the standard length, contact us for a quote on custom length hose. Straight hose can be cut to almost any length... longer or shorter than standard. Elbow hoses can be cut to have shorter legs if desired.
However, reducer hoses, hump hoses, and CAC hoses can not be cut to different lengths. If you need those types of hoses made to different lengths, that would be considered a custom made hose. Custom made hoses can be made to your company's specs, or branded with your company's logo, or both. Due to the necessary set-up for custom made hoses, they can not be done for one-off applications. They are for commercial entities only - minimum quantities and set-up charges apply. We can make virtually any custom made hose concept a reality, contact us for information.
