Default Lower Control Arm Lengths for 2.5 lift

I just picked up some Teraflex 2.5 flexarms and have the TF 2.5 coil lift. What lengths are people running for JKUs, and what castor angle does it correspond to? Same length on the driver and passenger sides? TF recommends making them different lengths to correct the tendency for JKs to pull to the right, but I've read some mixed reports about this. Any help would be much appreciated.

I just installed the teraflex lower control arms the other day. I set them at what the sheet said, It's at home, but I think it was 23 1/2" on passenger and 23 1/8" drivers. Not exactly sure. Drove it to work today, no pulling and DW seems to have gone away. Everything is good but slight vibration from up front that I have to track down.

I have read on some other forums that the vibration may have come from the arms being different length, and some people had the vibration go away with making them the same length. May be worth a try

Well, couldn't wait. I adjusted my fron lowers before work. Went to 23" like mentioned on another thread... can't think of it now. Vibration went away, but the DW was starting to sneak in a bit. Going to adjust them a bit longer. On my next day off...or sooner.

Be sure to check the balance on your tire's . I had a wobble at 50 mph after I put on my 2.5" Coil Lift on friday. Took it to the tire shop today , and had the tire's rebalacned . no more wobble , the tire's were out of balance.

FYI I have the same lift and my front lowers are both 23 and have not had death wobble (knock on wood)
