Does Single-Leaf 6K Leaf Spring e34SR Have a Pilot Nub for U-Bolt Plate

Question:

Part # SP-115275, Does this spring have for lack of a better term a pilot in the center for the u-bolt plate to fit over?

The 1-Leaf Double-Eye Spring # e46SR does not have a center bolt as found on the comparably-rated 6K spring # e34SR. That center bolt head, or pilot, is not present on the single leaf spring because it is not needed as it is with multi-leaf springs. You can still install this spring using a u-bolt plate that has a center hole.

Although these two springs share the same dimensions and weight capacity (25-1/4 x 1-3/4, and 6K) if you are replacing a multi-leaf spring you'll want to stay with a multi-leaf type as a replacement in order to maintain the original ride height.

Trailer leaf springs should always be replaced in pairs to ensure the trailer will track straight.
