Manufactured by PSC, this gearbox utilizes a custom machined housing originating from a 100% new current-generation Mopar ‘Big Box’ in order to accept heavily oversized bearings. This gearbox is the strongest and most durable option out there for any Ram 2500/3500 truck, and is built to order for your trucks’ configuration. Will fit any 2003-2009 4×4 Ram 2500/3500.

 

For 2003-08 trucks

  1. This upgrade still does not require any changes to your truck. This can be run with stock hoses/fittings, power steering pump and fluid, pitman arm, and steering linkage.
  2. In some rare cases, the factory gearbox came with smaller M12 bolts that will need to be upgraded to M14 hardware. While this is a very rare circumstance, the factory frame sleeves are already sized for the larger hardware and all taht is needed is the 3 newer bolts.

  3. While this gearbox does not require changes to anything else, this is a very good time to upgrade your steering to the large sector shaft and 08.5+ T-style Mopar steering if you have not done so already. This does require a new Pitman arm. Even for those trucks who are running the adapter Pitman to run the 08.5+ steering on the original gearbox, we still STRONGLY recommend upgrading to the larger sector shaft and getting a new Pitman for it. The size difference between the factory sector shaft and the later upgrade version available on the 2010-13 trucks is huge, and many 03-08 sector shafts have snapped off completely at the gearbox interface, particularly when used with drop-pitman’s and tall lift kits.

For 2009 trucks:

  1. This upgrade does not require any changes to your truck. This can be run with stock hoses/fittings, power steering pump and fluid, pitman arm, steering linkage and gearbox bolts. Note that the 2009 model year was an oddball year with many unique parts; it is best to confirm which input type you have and that you have the large-output sector shaft for the 08.5-13 T-style steering. The input shaft can be checked by removing the bolt holding the input shaft to the gearbox, and checking if the input on the gearbox is either fully splined or is a D-style shaft with a flat face.
