Rear axle air bags

I want to put air bags on the rear axle. Problem is the exhaust pipes would be within a few inches of the pipes. Does anyone have air bags that still have the exhaust pipes running over the axle? I'm a leary of the heat issue with this setup and I hate to think of having to reroute the exhaust.

Well that is good info. If I had to reroute the exhaust, both pipes would have to be routed out the drivers side because of the propane tank on the passengers side. Then I have to deal with getting the pipe around the drive shaft. Any others out there with air bags?

Lightbulb protect

If you are still concerned with your pipe to bag clearence and possible heat transfer I would suggest fabricating a simple heat sheild to sit between the two. Mounted about an inch from the pipes. This will help isolate the heat from the bags and as you go down the road remember that airflow under the unit will help to move the heat out. It should be noted that air bags are constructed similarly to tires and are capable of withstanding so serious heat.

I was thinking about fabricating a heat shield. Whem2fish what kind of air bag kit do you have? It seems to me the last time I looked, it was going to be a Firestone air bag kit.

One warning tighten the U bolts that go around the rear end more than they say seems like it was 20 foot pounds if not the bag mount will slip and damage the shock I learned this myself

Well I ordered the air lifts today. $262.00 including shipping. Plus I found that there is a $50 rebate from Air Lift. I now have a rear right leaf spring that is creaking loudly. Sprayed WD Specialist but is still loud as heII. More stuff to do...

If you need to lube the rear leaf springs you need to jack up one side until they hang free. I am not sure what wd specialist is but wd-40 is not a lube and will not lubracate any thing as it evaporates fast. Try a chain lube from a motorcycle shop.Really though leaf springs are not lube as a rule.

Lifted the frame and pulled the bolts. ( not all of the way out ) and put anti seize on the bolts and Fluid Film on the leafs. It did quiet it down but there is still a slight creak but I think that will disappear once every thing is worked in. Bags should be in on Thursday.
