Inboard Bag ????? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Question for you guys, I am working on my 72' Burb slowly but surely, and the time has finally come to set up the rear bags. I already have the notch done, and raised the tank etc. but my question is have any of you guys ran the bags inboard the frame rails. I already have three inch custom blocks, and my trailing arms are touching the frame where the factory spring went, so without major modification to either the frame of the trailing arm I can't put them there and have it as low as I want, so again have you or anybody you know ran the bags inside the rails? and how well did it work? I am aware that body roll would be significantly worse, but how much? I will run the shocks to the very outside of the axle so that will help, but just looking for someone with first hand experience.

Thanks alot

Robert

DO NOT offset the bag on the trailing arm! My first bag setup on my burb I did that....thing twisted alot....I never drove it. You can mount the bag in the middle of the trailing arm and move it to the inside of the frame rail. Make sure you do a 2:1 ratio so you get enough lift.

I'm in the process of converting my 67 SWB from a ladder bar w/ coil overs to ladder bar w/ air bags. Because of the ladder bar locations and the exhaust system, I've located the bags behind the axle and directly under the frame. I'm not try to lay frame or any of that, just make the truck ride smoother so my "honey" will cruise with me. Those coil overs may be great for the track, but mine are way stiff for the street. My frame is notched 2 1/2". I don't have the exact measurement from the bottom of the frame to the street with me, however, I can measure it tonight and drop you a note. I'm shooting some pics of the process if you're interested. I'm not real hip on how to post them, but I do know how to email 'em.

If I run them inside the frame they will be mounted to the axle about 6" forward, not the trailing arm, so I am not worried about that. Alos the bags are the Slam Specialities RS-82's which get about 8"s of lift which should be enough to untuck the 20"s. Thanks
Anybody else?

Oh yeah, in response to the 2:1 ratio as well I still need to have a pretty good load capacity. The Burb will see the occasional trailer, and just having alot of people in there aswell. I figure the closer the bag is to the axle, the less lift I will get, but the better load capacity.

Correct! Don't forget the sway bar. They help alot.

TOYOTA61384 · 03-29-2005, 06:25 PM

I have an addiction to throwing side to side, so I don't think a sway bar would be in my best interest, unless I made it removable so I could only use it while I was towing? I'm not too concerned about that right now, I just want to know if anybody had mounted them like this before sucessfully, if not, I guess I will let you know if it works.

Thanks
