Spring Pad Options
Choose the spring pad option that best fits your trailer build.
Spring Pads Welded On Axle
When spring pads are welded on the axle, the axle will be built in an underslung configuration where the springs mount underneath the axle and the axle sits 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.
If you need spring pads welded in a custom location that is not listed in the available options, simply enter your desired spring center measurement and spring pad placement in the order notes during checkout. We will review your order and contact you to confirm all measurements before building your axle.
