Commentary on Mopar XHD springs.

Your right. The factory 340HD springs were the same number and leafs per side. The XHD springs are not and from what I've seen were used only on big block cars. At least that's all I ever saw them on back in the day. Nevertheless wasn't the Mopar XHD springs what the topic was about? Not the 340HD springs?

Yes, but that link that I posted on the prior page - and any others I could find for what are being sold as XHD - define them as: "XHD Leaf Spring - Original Equipment
These extra heavy-duty springs are just like the bias design production springs that were stock items on 1968-72 A-body vehicles with 340 high performance engines ... ".

So ... dats da angle I wuz cum'n frum ;-)
