I just ordered the new 5100 adjustable for a 2015 4x4 AT double cab. I read a lot of post for lifting the fronts and just couldn't bring myself to use a spacer. I found the shocks last night (front and back) for 14/15 models. I called around and no one carries them, checked Bilsteins website and the query said they don't have that part yet. Order them from a company out of California, SevenSaturdays., I was skeptical and ask why they had them and know one else does. He gave me the answer, he knows a guy at Bilstein and was given 10 sets. I believe their are 3 left. Guess we will see if they work.
The dealer is sevensaturdays.com
