I don’t think anyone would argue that it’s a dependable and reliable system. That isn’t it’s weakness today. Today’s issues with torque tubes are that they often leak, and parts are extremely difficult to find. Add to that the extremely limited gear ratios available now that it has been out of production for over 50 years.... the durability isn’t the issue. The issue is your stuck with it exactly as it is right now, leaking and nearly impossible to find parts/gears for.
- What parts are hard to find?
- 3.55 and 4.11 final drive ratio R&P are readily available
- no leaks, if you are careful
If you want more/faster: yes, you (or, your local/reliable/knowledgeable truck shop) would need to replace a lot of parts (at what cost?).
