I cannot type but let me try.
Air bags, when inflated, give a much more harsh ride than actual springs would. No matter if variable rate or constant rate.
Once that bag is placed into effect, by the load, it its very stiffness which affects teh ride. Under Load, no load, no air, no effect.
Springs providw a choice, Keep the OEM Ride,, with a variable rate spring. Squat will still occur, though not as much as OEM SPrings. Once that varaible rte springs is compressed to acertain point, then the rate gets tronger and weight is met with more rersistance, similar to an air bag but not nearly as firmly. In teh case of constant rate spring. the OEM ride is no longer there. The spring is stiffer, wit the same rate of compression, throughtout. ye, again, for a bag to provide teh same amount of resistance, the ride will be better with teh spring.
WHich do you think is a more permenant solution? Metal Springs or flexible air bag?
Which is going to last longer?
A variable rate Tuftruck spring, once installedm is done. Nothing ever needs be done again,. Its going to be able to handle 50% more payload and, when not supporting a load, will give the original OEM Ride. With lighter loads, same OEM SPring liek behavior and ride will occur. It si sonly when getting serous about things that the springs will shine and ride will begin to be affected.
Same cannot be said for air bags got to fill them. if not enough air for the laod, add more air. when load is gone, bleed air to get ride back. constant mfarting around and, the ride is never a good as actual physical springs.
SPrings can be bought for less than $250. Truly Excellent springs.
Ones that a ton of members form various forums, have used for years.
Now, if springs do nto do the job, one can always go with air bags, although, at that point, I;d be stressing about the axle not being able to handle the load.
The Axle is teh weak point in all of this.
I've used bags over the last 40 years, gt a set in my wife's explorer right now.
Even had them in trucks, but only after the springs were upgraded.
This Ends my Peach.
Carry on
