Traxxas GTR 139mm Progressive 0.937 Rate RC Shock Spring - 8443

The Traxxas TRX8443 GTR shock springs are 139mm progressive rate replacement springs with a 0.937 rate, supplied in a natural finish with an orange stripe identifier. Designed for Traxxas GTR shock absorbers, these springs offer a progressive rate that firms up as suspension travel increases, providing a different suspension response compared to linear-rate springs. If you're replacing worn springs or experimenting with suspension tuning on a GTR-equipped Traxxas model, these are a direct Traxxas spare part made to fit the GTR shock body without modification.
