"I'd like to lower my dually, but I tow a trailer..." So do we... a 40ft triple axle gooseneck with all of our show displays inside. Nearly all of the semis that you see going down the roads today use air suspension. There is no reason that a 1 ton dually can not be lowered dramatically and still carry its intended load capacity. But you do have to use the right parts. It doesn't drag the ground and we don't have to creep up on speed bumps. AirBarHD™ is designed to lower your 1 ton truck dramatically (as much as 14") while improving the ride quality and maintaining the oem load capacities and a safe ground clearance. It is the perfect answer to the various loads and terrains that a tow vehicle will encounter. Now you can get that "In the Weeds" stance and forget about bottoming out or living with a harsh ride when you're loaded!       Bolt-on installation, NO welding required!   Heavy duty Firestone® airsprings to maintain OEM load capacities   "Bridged" airspring mounts for strength and durability   Pre-engineered mounting hardware to maintain ground clearance, driveline angles, tire clearance and load capacities   Improves ride quality. A softer ride for passengers and the trailer. No more harsh ride while unloaded.   Better handling!         Application Rear AirBar™ Front CoolRide™ Front ShockWave™ 73-91 GM C30 Truck (88-91 Crewcab square bodystyle) ABAR11004 ARF5002  N/A 88-00 C3500 Dually (88-91 is ext. cab only, round bodystyle. 92-99 is ext. cab and crewcab) ABAR11006 (requires Belltech C notches sold below) ARF5012-LCA (includes tubular lower control arms)  N/A Belltech C-notch for 88-00 C3500 BEL6911     01-04 GM HD 1 Ton Dually ABAR11100 (Includes our 2 piece bolt-on boxed C notches)  N/A ARF5011-LUCA (Includes tubular upper & lower control arms, steering arms, transmission crossmember, balljoint adapters & ShockWaves) 99-04 F350 Dually ABAR11995 ARF5006 (Includes special camber adjusters)  N/A 94-02 Dodge 1 Ton Dually ABAR11008 ARF5008  N/A       Compressor systems are NOT included with the systems listed above.       Return to catalog table of contents
