Spring Pads Welded On Axles
When spring pads are welded on the axles, the axles will be built in an underslung configuration where the leaf springs mount underneath the axles and the axles sit on top of the springs.
Spring Pads Shipped Loose
Choose loose spring pads if you want maximum flexibility. Loose spring pads allow you to weld the spring seats where needed for either:
-
Underslung Configuration

Overslung Configuration
Custom Spring Pad Placement
We can weld spring pads in a custom location for an additional charge.
