Re: If you could design a spring....
Generally a longer spring is needed to make significant improvements. The longer a spring is the more even
the pressure though out its range of flex. This is due to the tension buildup. Leaf springs are measured and
specified for the first inch of travel. Every inch past that increases the storage of energy. A long spring
can simply be compressed further with less buildup.
GM also built early blazers with a single leaf. That was done, I am sure, to reduce the friction coefficient.
Friction and espesially rust, do add to a springs stiffness, but very erratically.
Improvments can be made by using the teflon pads mentioned. You could also use a thin sheet of teflon
or HDPE to improve flex. We used to use teflon on race cars springs, but it didnt wear well. HDPE should
wear better. I always clean the leaves and grease them with Blue marine grease.
You might play with a softer stock length, and a higher arch to maintain ride height, but I doubt you will see
much gain with that configuration.
