Most kits are 100% bolt-in, no drill, no cut, no weld and no special tools required for installation! An experienced wrencher should be able to install various systems in 1 to 3 hours.

ASAM & CRM rear axle mounts are bolted to axle and frame members. Air springs are fastened at both ends. They're designed to allow full travel of factory & lifted suspensions. 4" & 6" lowering CRM kits require limiting chains to be installed and are provided with those kits.

Installation instructions are available for each application. We ship most kits pre-assembled with some fittings and air lines mounted and leak tested. Connections via composite push-to-connect fittings will need to be performed by the installer. All air systems are built, bench tested for operation and checked for leaks prior to shipment.  Please read the manual that accompanies any Viair compressor purchase. A system rated less than 100% duty cycle should not be used to fill tires or blow horns.

Kits are laser cut from 304 Stainless Steel that has a tumbled finish. Stainless Steel and Grade 8 fasteners are provided in hex head & carriage styles with serrated flange nuts. They are used for safety, convenience and reduce installation time.

Stainless Steel mounts are warrantied for life. Warranty is valid for original purchaser only. Original proof of purchase is required.

Air springs are warranted against manufacturing defects as long as you own them. The warranty is valid for original purchaser only. Rubbing, chafing, abrading, melting, overloading, corrosion, low or no air pressure damage, UV sunlight exposure cracking and/or road debris damage are not considered defects. Original proof of purchase is required.

Viair compressors, TGE pressure manifolds, solenoids and relay electronics carry a one year manufacturer warranty. All warranties are effective from original date of purchase. Original proof of purchase is required.

Standard kits are supplied with DOT (Department of Transportation) rated Composite Push-to-Connect type air fittings . IT IS IMPERATIVE THAT THE AIR LINES ARE CUT AT A CLEAN 90 DEGREE ANGLE TO PREVENT LEAKS. A UTILITY KNIFE BLADE IS PREFERRED, DO NOT USE SIDE CUTTERS! INSURE THE AIR LINE IS COMPLETELY INSERTED INTO THE FITTING. Leak checking is customer responsibility. We use blue DOT rated air line. This provides a visible aid for others that service your vehicle. 

Standard kits are shipped with one air valve for filling. This air valve fills the springs simultaneously. This insures one air pressure in the system and increases safety should an air leak or rupture occur. Those with slide-in campers or commercial rack systems the can be loaded unevenly or have a high center of gravity should control air springs individually. Additional air fill lines are available on the “SHOP” page.
