AFCO 20231M Discontinued alt spring help :(

You might want to go with the +1" Mopar oval track springs, P4529415. Not sure if summit has those, I know they only list the regular 414's the last time I looked. I've heard the oval track springs run a little on the soft side. Not an issue for spring rate, even the XHD's are only 110lbs, but the arch may put you lower than you want to be.

But that's just what I've heard, I haven't actually run a set of the Mopar oval track springs.
