The website says it requires a 2" bumpstop ? is this required only for 35's i'd guess ?
I've scheduled my lift install for next Monday.
I'm doing a Rubicon Express 2.5" std lift kit, but improving the parts with Synergy stuff, mainly i'm having this installed:
RE 2.5" coil springs with their rebranded 5100's
front/rear brake line brackets
Teraflex front Disconnects 0-3"
Synergy adj front track bar
Synergy Adj lower control arms
and for the rear, the trackbar bracket included with the RE kit seems a bit too cheap, and from reading on the stickies about certain brackets causing issues with the stock mount because their lack of proper support, i placed an order a couple of days ago adding the synergy rear track bar bracket to my list.

I wasn't going to add bumpstops because the instructions in the RE kit specifically say their kit was designed to use 35's and the included bumpstops, but if 33's are to be used, then the included bumpstops are not necessary.

Would i have to add those bumptops with 33's and this particular synergy rear track bracket ? i have no plans of switching sizes anytime near the future, so i'll have 33" for at least 2-3 years.

Thanks a lot.

 

The bump stop length is required for clearance of the track bar mounting height increase.

Plus chances are you'll need the bump stops to keep the longer shocks from bottoming out.
