Bags come and 'bags go. No, we're not talkin' about old girlfriends. We're talking about airbags and airbag systems. Your girlfriend is a whole other matter, and you should look at another magazine for that advice. KP Components, located in Hilmar, California, has just the answer for your old 'bag woes: a six-link cantilever system that eliminates the 'bag-over-axle kit that everyone has been doing for years. The benefit of using this system is that it moves the 'bags from above the axle in a traditional application, to the link bars, which provides a mechanical advantage, thus requiring less air to lift the rear of your truck. The less air it takes to raise your truck off the ground, the softer the ride will be when you are driving it. The traditional 'bag-over-axle method only offers a 1:1 lift ratio, so if your airbag will extend 6 inches, that's how much lift you'll get and it will take a ton of air pressure to get there. The KP system multiplies that ratio several times for more lift and a softer ride.
If you're not handy with tools or just don't have the time and you want a pro-quality shop to do the install, call a reputable shop like Master Image Customs. MIC, as it is better known, has a new shop in Mission Viejo, California, and is a distributor for KP Components. When the folks at MIC heard about our old-school Silverado buildup, they said "How can we get some of that action?" Adam Diaz and crew proposed the KP six-link system, and we said, "Hell, yeah," because the crew is so well versed in 'bagging Chevys that they can finish the job in less than five working days.
Our project truck is an '02 Chevrolet Silverado, currently sporting a 3/4 drop using drop springs. It looks good and rides decent, but something is missing. We wanted a kit that can lay low and smash rocks, but we also wanted something dependable that we could use and drive on a daily basis.
We know what you're thinking; we want to have our cake and eat it, too. Damn straight, little camper, we do.
Using a combination of the KP six-link kit and MIC's check valves, tanks, switches, and wheeltubs, we were ready to 'bag and drop.
Because of time constraints and because the truck is going to be driven daily, we chose to not cut out the front fenderwells. Granted, this would prevent the truck from laying even lower and complete the look, but that may come at a later time so stay tuned for that.
After the KP Components' kit was installed, we gave it the ultimate test and drove our Silverado over the Ortega highway, which is also known as the 74, a narrow, winding, mountain road going through the Cleveland National Forest that connects Orange County to Riverside County. For those of you who aren't from the SoCal area, get out your atlas and check it out, because you'll be amazed at this two-lane, scary cruise up and down a mountain.
The truck rode and handled like a go-kart. Common sense says you can't lay it low and cruise like a mad man, but you can set a comfortable ride height and enjoy. The truck is driven daily on the mean streets of California. But, it's mainly a freeway hauler presenting no problems with the suspension. In addition to our regular work commute, we also cruised the Silverado all the way to Vegas for a photoshoot and then back to L.A. in a pouring rainstorm. It was no problem. The suspension and 'bag kit even unexpectedly came in handy when we came in contact with high flood water. A flick of the switch and the truck raised a few more inches to safely clear the raging stream. Who says inches don't matter? Other than a little rust on the exposed bolts, the suspension came out unscathed. So, now we can say we made it through hell and high water and survived.

There have been countless how-to articles on 'bagging a truck, so there's no point in rehashing how to do this install. Instead, we are going to give you a down-and-dirty summary for readers who are new to lowering and wondering what consists of 'bagging a truck.
