Despite my efforts to allow for max room, the larger OD bags were too close to the pocket edges for me. You could possibly get away w/the smaller diameter bags on a lighter set-up (sbc vs BBC) but my BBC/TH400 requires ~100psi to achieve ride height & rides very decent. Smaller bags would likely require more PSI which adds spring rate to the mix.

Using the cups adds to the overall spring height which I didn't want. By pocketing the arms, they sat into the arms like the coils would. The way I did mine also kept the 'pocket' flush w/the bottom edges of the arm.

In the end, I wound up using PB's 1" Forward lower arms so I could use the larger bags w/o issue & used home fabbed upper plates that attach under the x-member...

I plan on using the 2600s because that is what the PB rear kit uses and what they use for their front kit.

What you did to your lower A-arms is what I was trying to describe.

* What thickness plate did you use? 1/4" is what I was going to use.

I think that is what I am going to do first.

I'd like to eventually go to a full PB Fab front cross member - Just need to pay for my kid's school first ($$$)
