Marko,
There are several kinds of helper springs for leaf springs.
1. Clamp on half leafs. These can apply high pressure and stress to the
clamp-on point that may cause the original leaves to crack. It happened to
me once in my youth.
2. Full length helper leafs. These mount between the leaf and the mounting
plate. A good method.
3. Coil springs over the shocks, either add-ons or built around the shock.
Can be difficult to install fully extended shocks.
4. Coil springs clamped on the axel housing, under the frame. I had a pair
of these from an earlier vehicle that I put on my Dodge. They are 1 inch
short of contact with the frame in the unloaded position. Do not affect ride
until a load is added or the spring is flexed an inch or more.
5. An extra full length leaf added to the original spring. The best method.

Subject: [FWDLK] Helper Springs
Hi, I installed heavy-duty helper springs made by Superior Industries to
the rear leaf springs of my
'61 DeSoto coupe. I bought them from JC Whitney (14BB1103N). My first
reaction was something
else, but now when they are settled down I too have positive to tell. Ad
says, that "they improve
traction and help stabilize vehicle for a smooth, comfortable ride"..
"restore springs to original arc"..
That's all true and now the car take curves fine without excessive leaning
and the rear-end lifted up
some amount with more erectness in appearance. So I can see better those
fins in rearview mirrors...
Has anybody else installed helper springs too? If so, I'd like to hear
opinions.
