Of the kits that ORD makes, none use the Dodge diesel NP205. The input is only 29-spline, but its larger that the GM 32-spline. In fact, you can take a 32-spline shaft and stir it around inside the Dodge. It also has a fixed output yoke that handles a huge 4" u-joint. It seems to me that would be the ideal NP205 to use. The "doubled" NP205 is already seeing twice the torque of a regular one. Is there an advantage to the larger input & yoke, or is it overkill? Hitting the (off?)road in a 350-powered 7000lb K30 isn't doing any favors for my wallet. A good diesel engine (like a Cummins or Navistar) may be in store for the future. Upgrades are going to be diesel-friendly. I don't want to be breaking stuff - doublers especially Any thoughts?
