Price: $75.00


The Zero-Rok light weight slider and hub are matched for a perfect fit. GM sold matched hubs and sliders to avoid sloppy fits. They have roughly 50 percent less clearance than typical aftermarket combinations sold elesewhere.  You still need some clearance for thermal expansion as well as proper lubrication. These are flank fit, meaning the fit is based on the side cleance of the spline to avoid and indexing error. Sloppy fits cause sliders to index the synchro rings with less precision. The hub is nitride hardened to avoid spline distortion. These are sold as ONE Slider and ONE HUB as a matched pair. These will make a great upgrade to any Muncie rebuild. This works with LATE STYLE RINGS ONLY!  If ordering two sets, they will be matched as 1-2 and 3-4 assembly.
