Leaf Springs-

Achieve a smoother, more comfortable ride with Speedway Super Glide™ springs for your 1928-1934 Ford front end! The ends of the spring leaves of a Super Glide™ spring have a unique nylon button which works as a dry lubricant to significantly reduce leaf-to-leaf friction. This allows the spring to move more easily, thereby giving a softer, quieter ride.
