Heavy Duty trucks ride rough, that’s a fact – that’s where we come in. In the endless pursuit to make your 3/4-1 ton pickup ride like your wife’s SUV, you’ll likely be replacing the factory, immobile leaf springs with a softer alternative resulting in a payload reduction. These airbags allow you to have your cake and eat it too!
Let’s talk about the bags. These proprietary airbags are noting from a catalog. Sage (Carli) worked with our manufacturer on a no-compromise airbag to meet the demands of OUR customer base. These bags Boast BILLET upper and lower pistons. The Pistons themselves are tapered as is the sleeve of the bag. Why? Larger upper piston, smaller lower piston means less spring rate ramp. If you were to run the same size upper and lower pistons (think every other double bellow airbag kit), you get exponentially increasing spring rate as the bags compress making the rear end short travel, volatile and VERY hard to control. It’s stiff until it stops, then rebounds (bounces out) VERY hard. If you’ve ever been in a truck with these style of airbags, you know exactly to what i am referring.
Our bags are still bags, the rate still ramps much faster than a typical spring would but these are the least of all available evils. We run Tapered pistons and limit the bags to 2,000lb. (ea.) capacity at their 100psi “working” load. We get the question a lot; what’s working load? Working load means the bag itself will see MUCH higher loads than the 100psi to which you’re inflating them. Throw a trailer on the back – theoretically, let’s say you fill these to 100psi to get the truck perfectly level. Drive down the road, hit a speed bump that sends the axle 3″ up the travel stroke and you’ve compressed that 100psi effectively increasing the pressure. So what pressure can these bags take? We test them continually – from every batch of airbags, since their release circa 2010, in a LOADED fixer. This means the bag is compressed to working height before inflated to failure. On average, they Burst between 500-600psi.
Every Carli product is designed from necessity, these airbags are no exception. Double bellow bags limit travel and ride harsh even at minimum air pressures. Enter the Carli Long Travel Airbags boasting no suspension travel limitations or ride quality degradation in a bolt-on package that restores payload capacity and adds adjustable load leveling capability to trucks with softer-than-stock leaf spring systems.
These are the bags run in every Carli Long-Travel Airbag kit – we don’t offer multiple bag lengths – just different bracketry to fit these to different applications. With the Airbag systems, we include all brackets and hardware to attach to the truck as well as air fittings, airline (1/4″ – can be plumbed to compressors, too) and schrader valves to install these bags for manual fill as this is the most reliable!
We combine a rolling sleeve bag and tapered piston design to provide 2,000lbs. of payload capacity per bag at 100psi max working load. These bags are offered for both 1″-2″ rear lifts and 4″ Rear lift configurations (adds the listed spacer to the bag system) to suit our 3″ and 6″ front suspension systems.
