Bilstein 5100s

Anyone know the reason why on bilstein 5100s you cant use 5th notch (2 inch lift) on 4x4, 6 cyl 6ft bed access cabs?

Have 2022 tacoma 2.7l, access cab w/ 6 ft bed but RWD, not 4x4.

Called bilstein and got different answers from 2 different people.

 

Sorry, don't know why, but I love mine....

 

ACLBs are lighter. The last perch is too much preload. It likely exceeds what they consider to be a good CV angle.

 

What confuses me why only the access cab 6ft bed models? My last truck had eibachs set @ 2 inch lift with no problems, bilstein just quoted me, what there specs say but no reason or explanation?

 

Update, bilstein emailed me back.
They quoted.
