Quad Bag Rear Suspension system
Go to New Quad bag system for a looksee at the newest addition to the Co-op parts list. It’s been a long time coming, but we’re finally there.
Here’s what Bill F. said about our “Q bag” system, he was one of our “beta” program customers:
We purchased a couple of Seats, Rear Bogie pins and a Quadra-Bag set-up from you last year and all have been installed. You were right about the handling improvement with the Quadra-bags……Great! Very timely too, I see that the New original air bags have been hoarded!
Rear suspension “Super greaser” bogy greaser

Man, we’ve got the new- improved bogy greaser in and they are PERFECT!!!
These making getting grease to the rear of the bogy pin a snap. Wether you have a large or small grease channel in your rear pins, this new kit has screw on fittings for either size. Try the big one, if it won’t go in, screw on the smaller tip and you are good to go!Thanks goes out to Gary Kosier for the design and manufacture of this great little widget— great job $60 for a set of 4– you can’t beat that! These are supplied to us by our good friend and GMC enthusiast Gary who came up with it. Good job man, you know he’s a crafty little devil, he’s always thinking. You wouldn’t know it by his manners but he’s thinking all the time– we need more guys and more little “widgets” like this. If you’ve got something that you think GMC owners can’t live without, let us help you promote it, we have many people looking to us for stuff like this. We are happy to help both the builder and people in need get together— it’s part of who we are.
NEW! Rear Suspension Air Compressor
This new compressor is a good replacement for the original V2 Delco compressor. It is a direct drive, single cylinder unit that runs at a higher RPM thus giving similar if not more CFM. The unit comes with a remote mounted intake filter system and even has 3 replacement filters included, a Braided stainless steel outlet hose and a polished aluminum cylinder head. The heavy duty (actually heavy weight) motor is well suited for our use. The included shock feet will need a new mounting plate in that the footprint is different but if you prefer, we can supply it for you for $10 additional with the kit (the interior mounted units do not need the new mounting plate). The complete kit is $285 plus shipping. The only other fitting you may need would be a new fitting into the tank and new plastic air line if you decide to replace the feed line to the tank.
Air Bag shut/fill kit
As you well know, if something happens to your rear air ride suspension and you loose air pressure, you are parked! When the air ride system is working it provides a smooth ride, that’s the reason GM used it. Ask any pilot, back-up systems for critical systems are very important. On a GMC motorhome, the rear air ride system is one such. There needs to be a simple method for isolating each air bag from the system and controlling the pressure to the bags independently from the rest of the system. This shut off/ fill kit does just that. Just above the height control valve between the wheels, you will add a positive shut off valve to isolate the air path from the air bag and a Schrader valve to enable you to fill the air bags there. Now, no matter what happens to your air compressor or control systems, you will always be able to pressurize the air bags and get home safely.
We have many customers who use this kit in place of their burned out compressor. Some GMC owners answer this safety question of emergency air bag inflation by explaining they carry Schrader valves to thread into the air bags directly . I can’t believe they have accomplished screwing in those valves at 2 AM in the driving rain on the side of the road. With this kit and a simple cigarette lighter compressor from Wal-Mart you can easily air up your system without a hassle! The added bonus of having the ability of taking out the air bags from the rest of the system for storage helps prevent the bag from losing pressure and “squatting” the coach over time.
Any way you look at it, this kit should be a must as piece of mind and a back-up. This kit is not rocket science and you may be able to piece a system together for yourself but for the price of $75 for both sides, it’s not worth wasting your valuable time poking through the brass bin at your hardware store. And of course if you can’t figure the darned thing out, you could always follow the directions that come in the box! But this, some day you’ll be glad you did! Add a remote mounted Schrader valve on the “T” skirt for easy fill access for $20.
