Muncie and Early T10 Synchro Slider

The M85-15 replacement slider is designed to fit General Motors Muncie and early T10 synchro hubs correctly.   Unlike poor quality sliders that fit hubs loosely,  these will restore your factory fit.  If you need hubs, consider getting our complete Zero Rok synchro assemblies. Precision heat treat, plug quenched 8620 alloy slider offers the best fit than any other slider currently offered.
