Hi Doug: I would say no. If the leaves are all new, the leaves from the same batch of steel, and the fabrication and heat treating done properly, the springs should perform the same—including slow creep leading to sag. I’ve seen a lot of 300’s at our shows that were jacked up in the rear due to new or re-arched springs installed. Our ’55 C-300 came to its restorer in 1989 with a trailer hitch and coil-over load-bearing “helper” rear shocks. So, if it was called to trailer-towing duty by its original owner, those seven-leaf springs could have taken a set. I put on new HD shocks without coil helpers and it did set a little low, but wicked-looking and close to specified ride height. The C-300’s were set up to ride a little lower than NY’s and Windsor’s as the significantly stiffer F&R springs on the C-300 enabled the car to jounce less without bottoming. I think this is true across the line of letter cars with the HD suspension standard or option. Your sport may have come from the factory with a standard suspension. On all ’64 300’s, the HD suspension is shown as a “2” under the “X”. The ‘64K ram car I bought for its engine had a “1” under the “X” and that is one of the mysteries of Chrysler life. Thinking it might have been special order for just part of the HD package—brakes, springs, shocks, sway bar. You might check for missing or broken leaves. Communicate with Eaton and let us know what kind of customer service you get. A top-notch outfit would want to pay to have the sagging spring removed and returned for failure analysis. In new cars, this could trigger a recall! Rich Barber Your neighbor in Brentwood, CA From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of 2HsandaHeritage@xxxxxxxxxxx [Chrysler300] HI Group, I installed new Eaton springs and KYB shocks on my 62 Sport conv. 2&1/2 years ago. Rear of car was raised about 1 inch and then completely level. Now left rear is 1 inch lower than right rear. Right spring has a slight upward arc and left spring is flat or has a slight downward arc. Should this have happened in just 2&1/2 years and less than 1,000 miles driven? Any thoughts will be appreciated.
