Lift with steering extension questions.

[mcgarvey2001]

I'm going to cut, sleeve and weld a steering extension for my 4" Brat lift but I'm wondering about a couple issues:

 

1.  The lift will increase the angles on the u-joints. At what angle does binding/longevity become an issue? I know a lot of bigger lifts are running around.

 

2. More critically, Subaru appears to incorporate a phase shift into the steering joint for the lifted rigs, but I don't see any mention of doing that on steering extensions in the forums. Are people just ignoring phase velocity cancellation?

 

Thanks,

Mike
