I've been doing a little research and noticed that the front axle tubes on the Rubicon D44 are actually the same as the D30 and that only the centre section is D44. Correct me if I'm wrong but shouldn't we all be looking to truss the front axle?

That being said, who offers truss kits?

 

I think you'll find the D30 tubes are 2.5" while the D44 tubes are 3". I'm almost certain that's right. Of course....not having compared the two, I could be mistaken.
