so...the consensus is that it is okay to use them, as long as you don't lift the back of your car up 8-10"...if you use them like shock, essentially. this is great info and experience, i think i'll leave mine for now.

I've had them on my signature 6bbl car since 1972, never less than 30-40 lbs, sometimes 40-50. Couple of weeks ago a had to pick up some feed & since I was driving it, threw 400#'s in the trunk & ran shocks up to 100#'s. No problem. Had them on many '69 Camaro's, GTO's & they're factory on my SS elcamino, also, no problems. Guess I'm just really lucky.

Your not lucky you're using them correctly. Which we already agreed on.

Yes & yes.

Story time though about not using them correctly. I do remember a guy who bought a bright yellow 69, ss396 chevelle, new. Put L60's on 10" wheels & believe it or not, 180#'s in his hi-jackers. I rode in it once & every gear bang it felt like a rabbit. Kinda fun actually, except for hitting your head on the roof. I don't recall the car died a slow enough death to break the mounts but, I saw it one night on the side of the road after one of the shocks exploded. I understood that happened regularly. Boy, I miss the 60's!

The thing is , the weight of the body is borne by the torsion bars and leaf springs.

Once ago, in a galaxy far, far away, somebody with a rot-box had the upper shock mounts punch through because of rampant corrosion. He posted for eons about this, and it passed into Mopar "lore" - air shocks are bad. This is called "groupthink". LMFAO

There are other myths...




Not necessarily so. I had them on my Duster and broke the left shock mount out of the trunk with 25 psi in them. Absolutely rust free body.

I learned my lesson on air shocks by replacing two driveshafts becuase I had mine so high it messed up the pinion angle on a 62 savoy. Your'e right, the shifts were great fun for a 16 year old kid. The first time the shaft let go I about crapped my pants when it bounced off the floor a couple of times.

I think 120 PSI is a typical maximum. Generally, when the car is loaded to a certain level, a certain PSI will bring it to the correct ride height. I also have a '76 Eldorado which originally had automatic ride height adjustment. It didn't work anymore and the rear sagged, so I just replaced the factory shocks with Monroes. I just keep them adjusted so ride height is correct for a full tank of gas and no passengers or luggage, 65 PSI in my case. Pressure may vary within a range depending on conditions, but the height is always pretty close to correct. (should be able to find correct ride height in a chasis manual)

Thanks for reminding me about using air shocks to pre-load against axle reaction torque caused tire lift on the right side.

Just for the sake of discussion,
say you were going with a friend to the strip
to run a Ram pickup a few times.

A clamp on the right rear leaf spring is a cheap and simple trick to reduce problems at launch.

Would a single air shock absorber temporarily fitted on the right rear also allow some adjustment for launch improvement?
What starting air psi in the shock,
and what starting air psi in the right rear tire,
versus psi in the left side tire?

Keeping in mind the relatively simple leaf spring changes Chrysler SRT engineers did
to the right rear leaf spring suspension
of the SRT10 Rams in later model years,
what other relatively cheap and simple mods
will help a Ram pickup launch ?

the gasoline tank is left side mounted,
so perhaps fuel level should be low for more reasons than just general weight reduction?

should the spare tire be removed from the cable winch mount underneath and moved into the cargo box on the right ?

Should the tailgate be removed from its rear mounts, but secured in the cargo box on the right side too?

Should the moved weight be over the right side centerline of the axle, or to the rear?

Around 25-30 psi is fine.(25psi is the usual minimum pressure recommended on most air shocks),D.
