The Dana 300 transfer case is becoming one of the most easily upgraded transfer cases available for both early and current Jeeps and tube-frames. Our company has completed a line of upgrade components for the Dana 300 which covers everything from super-strong 4-to-1 gears and 32 spline front output shafts to a variety of input gears and rotation plates. All of our Dana 300 upgrade components are designed and manufactured as independent projects of JB Conversions, Inc.. We are not jointly involved with any other aftermarket company in the design or manufacturing of these components.

Our front output shaft kit features an all-new precision machined output shaft equipped with the same 32 spline configuration found on the NP205 transfer case. The kit includes a new end yoke, bearing and small parts kit.

Our kit comes with a 1310 CV yoke (reference Spicer Part No. 2-4-5341) however a 1350 non-CV yoke option is available from us. The following part numbers are compatible with this kit:

Note: Some larger yokes must be machined to a 1-7/8" OD to match the seal supplied in the kit. The Spicer yoke numbers are as follows:

  • 1310 non-CV Yoke: Spicer 2-4-4191, machine to 1-7/8" OD
  • 1330 CV Yoke: Spicer 2-4-5441, No machining required
  • 1330 non-CV Yoke: Spicer 2-4-5521, machine to 1-7/8" OD
