Bore out service - D300 Retainer Transfer Case Why Choose the RAD DesignsIf you are upgrading your Dana 300 from a stock 26 spline front output shaft to a 32 spline, you need to bore out your input retainer to fit the upgraded larger shaft. For customers that are not able to do this on their own, or do not have access to a machine shop, Behemoth Drivetrain offers bore out service for these retainers. The service works for both the Behemoth Drivetrain model 32 spline shaft and the JB Conversions 32 Spline front output.
