The Fabco 306J-1 (also referenced as 306J1) is a two-speed, two-shaft transfer case with a 0.86:1 gear ratio. Sourced as a genuine Fabco component, this unit is designed for heavy-duty truck applications where a transfer case with dual-speed capability and a dedicated two-shaft configuration is required. The 0.86:1 ratio is the defining specification for this assembly, distinguishing it from single-speed and differently-rationed variants in the Fabco transfer case lineup. Pro Gear and Transmission carries this part for buyers who need to match an exact OEM specification. Call us to confirm proper fit for your application.
