Default adjustable, flexible tj/lj short arms

i got an 05 lj rubicon. its totally stock. im looking to improve on the stock suspension. it will be low so long arms are not necessary.
it will never be lifted very high(1.5 to 2 inches max). it wont wheel alot.
dont try to convince me how much better your long arms or radius arms are.

keep in mind it all must fit in the stock mounts(they wil be reinforced).

what size tubing? 1.75? 2.0?
wall thickness? is 1/4 inch enough?
joints on both ends? or one joint, one rubber bushing?
what joints do you like to use?

i was leaning toward 1/4 wall tubing, with johnny joints at both ends.

i really want to build my own. i impressed myself on how my bumpers are coming along, and looking for my next project.

thx!

what was used on your rig in your avatar?????? use same materials, streetable/comfy joints in stock length to bolt into stock locations. I use 2"x.250 wall dom with weld in bungs and bushing adapters I turn up my self for factory bushings. 1.25" shank for adjustabilitly

How are you going to improve the stock suspension if you arent doing anything but replacing the stock control arms with ones that dont really fit the application? .188 wall 1.75" lowers and 1.5x.120 wall uppers, one end threaded for adjustment using 1" threaded uppers and 1.25" threaded lowers. Johnny joint on one end and an XJ lower control arm rubber bushing on the other.

ive broken a couple stock tj control arms. its no fun limping home or getting trailered by a friend. good control arms and track bars are a must for me personally.

i have been looking for small lift springs about 1.5", but they are not common.
ome has 2" but they are kinda pricey. i might go that route anyway.
i have seen steel spacers that basically relocate the upper springs mount 2" lower. im not a fan of poly spacers, but its an option.
im doing a 1" body lift for a tummy tuck, and as little suspension lift as possible. hi clearance fenders front and rear will allow what ever tire size i want. ive been buying up parts(mostly used) for future use. if i see a good deal i snap it up.

i would like to build my own control arms. ive always bought this kind of stuff.
its time i do this on my own. its not really hard. why pay someone else?

i saw curries arms have joints on both ends. that is probably not necessary.

i have read where joints on both ends can be more noisey.
rubber bushings isolate some road noise.
leaning more towards a good joint, not heims.

mostly looking for opinions from people that have done this b4 me.

personally i think the heims on my buggy area little small and wimpy looking.
they have been abused and held up so far, so what do i know?
