Re: {Chrysler 300} C300 coil springs

["'John Lazenby' via Chrysler 300 Club International" <chrysler-300-club-international@xxxxxxxxxxxxxxxx>]

Jack,

What is not included in the report below is that on C300s the rears were 7 leaves and NYer and Windsor were 6.  I suspect installing the twist spaces in the front coils will only provide a more harsh ride.  When I purchased our 300B those were in it and the car had still settled so much one had to lift up on the front fender to slide a floor jack under the car.  My thought is these spacers may have weakened the already tired springs even more.

I have this in my notes:  Front: C-300: 800#/inch, Rear:  160#/inch;  NY: 480/100; Windsor:  480/90 as per AMA specs. 

 

The stiffer ride of the 300 no doubt caused many Chrysler buyers in 1955 to buy the more comfortable riding New Yorker.  The 300 did get them into the dealership though.  I don’t recall our C-300 to have that stiff of a ride.

 

I have never heard definitively as to whether the deflection rate is per spring or total of the two.  If 800# is placed on the front bumper and it goes down 1”, each front spring is loaded to 400# and the individual spring rate is 400#/inch.

 

I do recall little metal wedges that could be forced between spring coils to jack the front end up.

 

Still suffering seller’s remorse and our old C-300 is for sale again.

My front springs are tired and probably should be replaced. I called Eaton and they don’t have them, won’t have them and don’t have the specs for them.

 

Any ideas or sources?
