Good. We need more of those types. Less go along to get along.
That means you're probably also open to learning things - another thing we need more of.
Further to the above on your part number research:
"My research shows that part number for front and rear shocks are different from non offroad trims vs off road trims. (This part is true). So the 1" inch is from the shocks.(This part is not.)"
Reason why some folks are buying the ORG springs from parts departments or as takeoffs from other owners is because, apples to apples, achieving a lift with increased spring length is ideal over achieving a lift via spring preload. If the ORG and non-ORG pack springs were identical no one would be seeking out the ORG pack springs. Spring rate also plays into this, but I've not seen specs on whether the rate differs between ORG and non.
For an on-road vehicle where the emphasis is in preseving ride quality, the hiearchy of preferred methods for attaining lift would be:
Spring Length > Rate > Preload.
A shock alone can only adjust preload by manipulating spring perch height. And this applies only to coil over suspensions (e.g. not Wranglers or rear suspensions).
I've even seen folks getting the ORG pack springs and putting them on the Bilstiens, so that they can run the 5100s at a lower perch theoretically improving the ride quality since they can get away with less preload.
ORG also includes different Shocks, yes, hence the different part number. But because they are valved differently, as advertised in Ram marketing materials calling them "HD Shock Absorbers...".
On the Jeep you didn't have to deal with any of this because the front suspension does not use a coil over design. The spring and shock are completely separate assemblies. But oddly I'd have expected that to have reinforced the notion that the lift is all in the Spring - because no matter what shock you put on a Wrangler, no lift is happening until you modify the spring or add a spacer/puck to it.
Either way, just adding detail since it sounds like you are curious about it, and since this is a forum after all and someone may review down the road for their curiosity as well.
