Using Non-Standard Gear Sets In The 2.72:1 Strong Box Underdrive
Our line of 2.72 Strong Boxes are designed to use gears from the following transfer cases:
NP241, NP243, NP246, NP231, NP233, NP236, and a few others that are very similar.
To use NV271 or NV273 gears in the 2.72:1 Strong Box Underdrive, you simply need to order your Strong Box specifically for NV271 or NV273 gears. We will make sure your Strong Box gear housing has the proper dimensions for NV271 / NV273. If you have already received a housing machined for NP241 or similar gears, we can modify it easily to accept NV271 / NV273 gears easily, and at no additional charge. You only pay shipping cost. NOTE: A NV271 / NV273 housing cannot be modified for NP241 or similar gears.
Other cases that can be used, but may require slight modifications include:
NP261, NP263, NP241 DLD, and a few others that are very similar.
This allows the 2.72:1 Strong Box to be ordered with any of the following input shaft spline counts, making it compatible with many domestic transmissions:
2.72:1 NP & NV GEARS
2.7:1 BW GEARS
2.48:1 BW GEARS
