To add a complete fast-up front onto an existing rear fast-up. This system includes an additional small tank to be plumbed together with the fast-up rear tank to create enough volume for the front and rear. Also includes an additional compressor to fill the increased volume, and valving to control the flow to the front suspension. And of course, the front suspension parts, along with all of the tubing, fittings and wiring to complete installation. Basic kit comes with bare tank (no specific mounting brackets), depending on where your rear components are installed, you may be able to add year-specific mounting brackets for the additional tank and compressor, see options in drop-down lists above.
