what size rear LCA's needed

Although not needed but was wondering what size rear lca's are recommended with a OME lift? Looking at the bwoodys and this is quoted from there site but offer many lengths
" Great for guys with lifted jeeps as well, we now offer custom lengths for an additional charge. Once you lift your jeep you shorten your wheelbase which chages your pinion angle, let us correct it for you with a custom set of BWoody Lower control arms!!"

Purchase there advertised set?....or go with a custom length that they provide?
Heres a pic of there lengths.

what do you guys think is sufficient for an OME lifted wk? Thanks!

Re: what size rear LCA's needed

Or instead of fixed arms get adjustable LCA's from a different company? And from which one?
Whats the consensus?

Re: what size rear LCA's needed

I have never put an angle gauge on my ujoints so I cannot say with 100% certainty that I am not overlooking a detail, but with it being a 4 link any amount that the jeep is lifted it keeps the pinion orientation the same, so long as the angle is split evenly between the front and back ujoints there should be no need to adjust.

Ultimately though, if this is money you wanted to spend, you would just need to do the measurements yourself while installing the lift, that would likely require unbolting the LCA which would take some care and thought as to what will shift around and move where. Then move the axle back or forward (twisting the pinion to the ground or to the sky until you are reading the same angles on the transfercase ujoint as you are on the diff ujoint, then measure how much longer the LCA needs to be to hold the axle in that position.

Realistically, there are hundreds if not thousands of lifted WK's and XK's most of which with unmodified control arms with minimal noted failures. My jeeps got 200k miles, and about 15k miles on a 2" lift with no issues.
