Was doing a little research and have been thinking about ordering control arm drop brackets. Thing is while i was doing research ive seen a few people mention that you should have adjustable UCA's. I was wondering if this is true and wanted to get a lottle more input on whether id need some or not?

My situation is i have a 3.5" RE lift measures to about 4.5-5.0 and will settle at about 4" ish

hving upper and lower adjustable control arm is deff a plus for fine tuneing front end alingment and if you add more lift you can just extend the arms but with that small a lift dont think you need both

This. Having both is a plus.

Soo I have fixed lowers and stock uppers so if i had a control arm drop do i need the adjustable uca's or would it be fine stock? And i dont plan on upgrading to a bigger lift

I know i saw something on here where a guy was running DB at 3" of lift and was having caster issues that required UCA's. DB also push your axle forward slightly. What are your reasons for wanting to upgrade?

Smoother better ride as well as droop/ flex

because arms are for 4 inch and up lifts maybe

brookhart63

He knew that when he started. Using DB's at that height is no problem. It just needs to be set up correctly.

having control arm set 1 inch lower than factory set ups a problem think about it

brookhart63

Understandable. There are many different things that contribute to flex. Ride however, depends mostly on CA angle and shock choice.

DB's at that height were made to be used with the weak stock LCA's. How long are your current LCA's?

read must have at least 4.5 lift .....http://www.roughcountry.com/jeep_xj_..._arm_drop.html

? I dont understand what your trying to tell me. You can run whatever suspension you want at 2-3" of lift. Just because they dont make the parts that bolt on to do this doesnt mean it is not possible..... Are you saying that running long arms on 2-3" of lift is bad? I believe KTM ran LA's, 36's on 3" of lift. Doubt he just bought the parts and bolted them on. http://www.jpmagazine.com/featuredve...j/viewall.html

Roughly 2" of lift on 40's and custom suspension.

Im running bilstein 5100s ans my lca are 16"

3 inch lift with 4.5 inch drop brackets your control arms are 1.5 inchs lower than stock set up dont think thats very good like negatve

brookhart63

Good choice on shocks. Your LCA's are slighty longer than stock so you might be able to get away with running your current ones with the DB's. I would suggest getting a nice set of adj. UCA's. That would help you dial in a very functional short arm set up.

Uh not sure if im right but i dont believe the DB's lower the mounting point 4.5".......
