Hi so my question is, I want to lower the rear of the aspen but can't find any one that has springs left for it. Do you know any other platforms I could use or if the newer Durango kits would work?
Thanks for any info

Kind of old question, but just in case - The Aspen have torsion bars and not springs and there are a lot of youtube videos and instructions on this site also on how to adjust the ride height. It's pretty easy to do but you have to measure carefully to get it right on both sides of the car.

The torsion bars are for the front only. Rears are springs/shocks with a bellcrank system to keep the differential centered.

Would need lowering springs.

The torsion bars on the front would affect ride height for the front only.

BAR-TORSION
DESCRIPTION
The front of the bar connects to the back side of the lower suspension arm. The rear end of the bar is mounted in
a anchor that rests in the frame crossmember.
OPERATION
The torsion bars are used to control ride height and ride quality. The vehicle height is adjusted through an anchor
adjustment bolt that increases or decreases the wind up of the torsion bar. Increasing or decreasing the bar angle
changes the wind up of the suspension arms.

Oops - you are right. I only changed the front (raised it).

Are you looking to cut a new one down or are you looking for lowered springs?

From 52855255AB - Chrysler Spring. Rear coil. [[spring - left rear, spring - right rear]] | Factory Chrysler Parts, Bartow FL, it should fit these:
