Leaf Springs Types
Practically all leaf springs that are now used on cars and trucks are of the semi-elliptic type. Because the semi-elliptic spring has the outstanding advantages of not only acting as a spring, to resiliently support the vehicle, but also serves the important functions of positioning the axles and of cushioning both driving torque and brake reaction.
Although not new to the market, the full taper spring is now very popular for suspension systems on light to heavy truck application as well as some passenger car suspensions. The major advantages to this type spring are its superior ride and overall reduction of vehicle weight.

Quality and Workmanship of Leaf Springs
1. Center hole
If made with good dies, it will be clean-cut. A poor center hole may set up additional stresses in the steel, which may cause premature breakage.
2. Trim points
Must be done with good equipment, to avoid cracking, chipping and rough edges.
3. Clips
Must be right size and shape to fit properly.
4. Eyes
Must be tight accurately sized; must be parallel and straight, to avoid setting up excess stresses in the main leaf. If the eye is too small, the bushing may be crushed when forced in. If the eye is too large, the bushing will be loose.
5. Fitting of leaves
Must be accurate, to avoid setting up excess stresses in steel and causing premature breakage.
6. Leaves
Must be fitted side to side, as well as surface to surface.
