Q & A

What's in the Box

Super Glide™ quarter elliptic springs feature a five leaf, 1-3/4" wide spring design. The ends of the spring leaves of a Super Glide™ spring have a unique nylon insert. This insert works as a dry lubricant, significantly reducing leaf-to-leaf friction. This reduction of friction lets the spring move more easily, thereby giving a smoother, quieter ride.

  • 1-3/4" wide
  • 20" long
  • Sold each, two required
