CU-0402 KEYSTONE SHOCK CONTROL SA-20

$3.50
Upgrade and cushioned underframe car with a cushioning unit from Keystone. This Shock Control SA-20 is a single-acting unit with integrated and shielded return spring. Identical to SA-20A and very similar to SA-20MS units. SA-20s were sometimes used as easy replacements in the field of the earlier DA-20 double-acting type which required a separate return Spring. Improve a kit or ready to run car with accuracy.
