they are good looking too.... very HD compared to the stockers, the splines are twice the length of the stock set and are deep splined in to the axle vs. the stock splines are stuck out of a taperd shaft. even the c-clip notch is beefier. all and all Cass has done me right. along with my LPW diff girdle, 4.10s,these axles,i should have a decent rear.
