• FOR ACCUAIR VU4 VALVE OR DIRTY AIR 8-VALVE SETUP
• Don't walk into the shop and see your bad ass bagger flipped over on the ground!!!  Use this on the low-pressure side of your bagger F R tank air setup, open the toggle switch valve to vent your system when dropped and left unattended. 
• Using this setup, if your valves ever leak or open for any reason, it will bleed off into the air instead of into your suspension, which could easily cause your bike to flip while unattended.  Small price to pay for big peace of mind.  This safety valve is set up for systems with a dedicated air line and a pair of valves for each shock and each fork tube, normally used on lay-frame bikes.
