I can't speak on the gears but on doing my research (this thread
and several others, as well as other sources) on beefing up my front axle, I believe I've broken things down to more bitesized portions. Granted, all situations are different but this is what would fit any situations someone like me would encounter. I have a 2007 JKU, currently with 35" tires and it is 90% DD and 10% off road (light to moderate)
[*]33" tires = Stock axle is fine for DD and light to moderate off-roading. For rock crawling, should consider gussets (the armor that goes on the axle "Cs")
[*]35" tires = Stock axle is fine as DD but for light off roading should install gussets. For moderate off roading, should install trusses (armor installed to the outside of the axle). For rock crawling, should consider sleeves (tubing that goes inside the axle)
[*]37" tires and up = DD should at least put on gussets and any off roading should have trusses and sleeves.
Then things come down to the money:
I have flipped back and forth on how I am going to beef up my axle for my 35" tires. I was figuring the Artec stuff was overkill for my needs and could save money going with gussets and sleeves.
Well . . .
Looking at Synergy parts for example, I found I could get sleeves and gussets for $165. Then I saw that for an additional $35 I could get control arm armor.
And that brings the total to $200.
So why not spend $250 and re-enforce my axle for anything I might encounter?
Add to the fact that the shipping was cheap (granted I am in the same state), I'm sold. In fact I placed my order but they are currently on back order but should have them in a week or so.
