I did a search and couldnt find any hard facts about this particular situation. Most of what I found say you "shouldn't" need longer brake lines unless you lift your truck 3+ inches. However, After my recent AAL install and seeing how extended the brake lines were with the stock shocks, I am concerned about how they will handle a longer Bilstein 5100 shock. I only have the AAL kit from toytec in the rear on non-TSB springs. ( 4 leaves all together). My plan is too use 5100s at all four corners and Maybe Eibach springs up front.
Thanks for any info!
