Same setup for me. I have a harsh “top-out” when unloading the front suspension no matter where I set my droop. Currently my FCPs are the limiter in the travel and that’s what is topping out.I'm also running SPC uppers and 555 lowers. Looks like we have the same configuration.
Just ordered the 786s from ExitOffroad. Will report back on how they compare with the FCPs and new droop numbers when I get them installed.
