As for the BJ flipping. 1. Do a search and you'll find some info.
As for what I can offer:
This shows the lower bj flipped and installed.
For the upper, it is currently installed under the upper control arm. Just unbolt it and bolt it through the top of the upper control arm...it's real easy lol.
As for the lower. Once you have the wheel off and the spindle unbolted from the control arm, you'll see how the bj is bolt to the arm from underneath. Unbolt the bj, and you'll notice that there's a hump in the control arm where the bj was mounted. Take a grinder and cut off this hump. Repaint, and mount the bj to the top of the control arm now where you ground off the hump. Keep the bj pointed down! (If you have 16" or bigger wheels you can point the bj up and really have it slammed, observe the lower pics below )
This pic below shows the upper flipped, and how the lower needs to be cut:
Now for the slammed!
This is with the bj pointed upward...can't do unless larger wheels, or the right offset is available: (I couldn't tuck the wheels I had and still turn the wheel due to the offset)
And now I am like this:
I got this way by, flipping the front bj's, reindexed the torsions 2 notches (had to replace the t-bolts due to bolt breaking, so while I was at it I reindexed), monoleafed rear with overload spring, 3" angled blocks, shaved rear bump stops, air shocks in the rear, Isuzu shox up front with bump stops removed.
I keep my rear end aired up a bit or else I'll ride on the shaved bump stops, so up front and in the rear I have about 1" of travel lol. The front still has the bump stop brackets...for now, and that's what I hit on hard bumps with the lower control arm...making for some hard hits on big bumps. The ride is fine on most roads, no bounceyness, but tightens your butthole when you see a bigger bump ahead
I haven't decided to remove the bump stop brackets. I may end up just going with dropped arms if I can find some used but on the cheap Then I can probably put the bump stops back in and have an even better ride.
Ok enough knowledge for today spent....oh the headaches
