High-lift mid-weight Tru-Spring - regular length

Medium weight Tru-Spring armature bar controls speed while maintaining proper point gap.

Tru-Spring Armature Bars

The Tru-Spring system of spring mounting ensures consistency in spring angle of deflection and eliminates all spring bending. Makes changing to thicker or thinner springs quick and accurate. Maximizes spring performance and exerts exact front and back spring pressure on the contact points of the machine.

There are two series of Tru-Spring armature bars - high-lift and low-lift. High-lift Tru-Spring armature bars are best for all long stroke set-ups, and short stroke set-ups with high compression. Low-lift Tru-Spring armature bars are best for short stroke set-ups with low compression.

All Tru-Spring armature bars are precision machined from 1018 low carbon steel with a rust resistant black oxide finish. Complete with #8-32 screws and washers. Available in two lengths: regular and long. Specify low-lift or high-lift when ordering.

IMPORTANT: Tru-Spring armature bars will not fit on some cut-back style machine frames. To determine if a Tru-Spring armature bar will fit on a machine, measure from the contact points to the center of the back spring mounting screw. If this measurement is 1 7/8” (48 mm) or over, a Tru-Spring armature bar and springs will fit on that machine.
