This system is designed for better handling. Each front air spring has a separate path to control "steering dive". As the vehicle enters a turn the weight is shifted to the outside front corner. The air spring should build spring rate under compression to control weight shift. If the front air springs are teed together, the air pressure will transfer to the low pressure side rather than build spring rate, resulting in a push condition. Using the 3-Path system prevents steering-dive by eliminating air transfer between the front air springs. The rear air springs can be teed together, unless the vehicle is unevenly loaded. 1 - Viair 450C Chrome Compressor 1 - Pressure Switch 110-145PSI 1 - Air Lift 5 Gallon, 8-Port Tank 6 - Air Lift 3/8in Chrome 300PSI Electric Valve 1 - Dual Needle Gauge 200PSI 1 - Single Needle Gauge 200PSI 3 - Rocker Switches 3 - Fuse Holders with Cover 3 - 15 AMP Spade Fuse 6 - 30 AMP Spade Fuse 1 - 40 AMP Heavy Duty Relay 1 - Single Relay Socket 50ft of 1/2in DOT Synflex Air Line 50ft of 1/4in DOT Synflex Air Line 2 - Thread Sealant Packet 1 - Air Line Cutter 1 - 1/2in Street Tee Fitting 2 - 1/2in NPT to 1/4in FEM Bushing Fitting 2 - 1/2in NPT to 1/8in FEM Bushing Fitting 1 - Drain Cock Fitting 1 - Inflation Valve Fitting 2 - 1/2in NPT Hex Plug 3 - 1/2in NPT to 3/8in FEM Bushing Fitting 3 - 3/8in Street Tee Fitting 6 - 3/8in NPT to 3/8in NPT Straight Fitting 3 - 3/8in NPT to 1/2in Line Elbow Fitting 1 - 1/2in Line Tee Fitting 3 - 1/4in NPT to 1/2in Line to 1/2in Line Tee Fitting 3 - 1/4in FEM to 1/4in Line Straight Fitting Chrysler 300 - Front Includes: left and right air struts Chrysler 300 - Rear Includes: bags, brackets and shocks for both left and right sides Check out the air kit upgrades section at the left for upgrades and additional items.
