Muncie Side Cover HD Detent Spring - 20LB

The M-156-001 20LB heavy duty detent spring is a great update to older weakened springs. If you feel that vibration or long shift handles may cause falling out of gear this new spring may help and was standard on later 1969 and up Muncie 4 speed transmissions. Made in USA.
