Spring spacer front-to-rear interchangeable?

[shinysideup2]

@Black or others... Would you happen to know if spring spacers for our 3rd gens are interchangeable front to rear? I'd like to raise my rears (on Ranchos QuickLift) a small amount. Readylift has a 1.5" "leveling kit" (front spacer). I'm trying to figure out if I can use these in the rear.

I've got the Bilstein 6112's up front, so I can just move the lower spring perch up when it comes time to lift.

BTW, I wish the Bilstein 6112 had more rebound damping. Around town, after going over deep dips at a "brisk" speed, the front end pogos a bit. The rears (on Ranchos set to 7 / 9) don't pogo at all - noticeably firmer than stock (50k miles), and the 7/9 setting is still pretty comfortable for me and the family. Perhaps Bilstein tuned the 6112 more for off-road (softer), but with their claim of digressive valving (damping curve increases more sharply for lower-speed movements), I would have expected much firmer damping at lower speeds, such as dip recovery, with damping tapering off at higher speeds such as bump recovery.

Thanks in advance

The spacers are not swappable front to rear.
If you go on eBay and search rear spacers you will find rear sets of varying sizes.
Granted they are not Readylift but a strut spacer is not really all that complicated.
Here is a 1.5” rear set.

Further to this, is there any known reason why you can't just put ride height leveling struts in the rear position? other than maybe the spring rate is to soft?

The older models you can then couple with the part a member makes to add height to the rear.
The newer Nivostat self adjusting or whatever the are called won't add lift without a spacer and I don't know how the spacer would effect how the nivostat works.

If anybody would know, @Black would know.
