Meaning mopar's leaf springs were very good from the begining and hold rate very well, even after decades of use. However, many people mistakenly think that a properly installed mopar spring should have an arch to it and when looking at their flat old springs think that "Geez, these things must be really worn out" and they replace them with new mopar springs thinking they are going to provide them with a +1, +2 +whatever lift they want only to find that the replacements also sit flat and their car is not lifted at all. At that point begins the incessent verbage that the springs are junk and not any better than the originals.
It is also does not seem to not be widely know that mopars XHD springs were designed to control spring wrap up for drag applications while still providing excellent handling capabilities for a street vehicle. A combination of which is not supposed to lift yer rear into the air. The XHD springs duplicate the factory specs, plain and simple.
For my recollection and whatever proof I can find in vintage mags and photos from the time, in stock trim most mopars sat level and E bodies in particular seem to actually sit lower in the back, AAR and TA excepted. Add the passage of time and the changing of tires and many mistakenly believe that a stock, restored mopar should have a rake when in reaility, very few did and if they did odds are pretty good the owner changed tires very soon after receiving said vehicle. It seems a lot of current owners have forgotten that these car began recieving modifications as soon as they got home. Wheels and tires were usually one of the first thing to get changed. How many members here can remember the exact tire size on their first car? Very few I'm willing to bet and that fuzziness leads to the mistaken belief that their current restoration project with 235/60 BFGs all around should sit higher in the rear, therefore my springs are crap.
