Is there any difference between boxed and tubular. It seems to me that the tubulars would twist easier, but I am no Einstein. I found a set of Lakewood boxed for 133 and some tubulars for 70. What do yall think?

I just installed some umi tubluar ones on sunday. unless there is a cracked weld your not going to twist theses things. there are pretty big, and they have beautiful welds on them aswell.

I have a some pics of them next to the stock stuff if you want to see it.

I have never had boxed ones, nor have I had 1000hp but I would highly doubt you would break one. maybe if your panhard broke during a wheelstand.

just my 2 cents though.

you can buy the boxed lakewoods for like a hundred bucks from summit. i boxed my factory one and put in energy suspension bushings and didnt see a difference in traction, but it did seem to stiffen up the back of the car. havent put relo bracket in yet though.

XX11 i just saw the ones on summit for $100. Thanks for the heads up though.

so which one is really better?
boxed style ! only see them on GM A-G-B and 82-02 F-bodies etc.
tubular style ! only see them on real race cars,4-link and ladder bars

Yeah i've heard there really isn't that much of a difference. I know if you want adjustables you will need tubular.

if you are sticking to street and a track day here and there, go with boxed...no point breaking the bank if you aren't going to put it to use

Given the similar size tubing square resists bending better than round, though round resists twisting better than square tubing.

However round tubing is also lighter.

I personally run a 1 1/4 c-moly LCA. It is very strong and more than enough for a street car with trips to the track.

Boxed is cheaper in cost, although most round LCA's can be adjusted which is an advantage if you ever use lower control arm relocation brackets or swap to another tire size or raise or lower the car

...go with the tubular adjustibles ...we are not talking a bunch of dough here - what is 150-175 for the set Vs 100?

Well I am not planning on getting relocater brackets or adjustable LCA's and I dont have 1000hp, so yall dont think it matters if I went boxed or tubular.

Not really a diff on a street car that is DD. But if you do plan on doing some heavy syuff down the line i'd go tubular adj.

When i go 9" i'm ditching my Boxed arms and going tubular adj.

your not going to notice a huge difference between the boxed or tubular LCAs if you stay with poly bushings for both ends. the great thing about the tubular arms is you have the option of runing a rod end on either or both sides which allows the rear to move in a more natural way rather than binding with the poly bushings. If your drag racing, go tubular or boxed with poly bushings... but if you want to carve corners, get some tubulars with rod ends on the axle mounts and poly bushings on the chassis mounts.

If you are going for handling, the boxed LCAs with poly bushings aren't the best idea. They cause the LCAs to bind when in a corner. It's cause when the body tries to move over the rear end (which it's supposed to do) and the poly prevents it. When you come out of the turn, the stored energy is released and it whips the rear of the car around...yeah, it's pretty not fun. For drag racing they are fine. But, if corner carving is your thing, the best bet is a tubular set with either dual rod ends, or a rubber joint on the body (for comfort, you don't have to replace them, and they are cheaper than rod ends) and a rod end on the axle. A poly end works on the body to, but they still don't function properly when turning and the polys ride isn't as nice as the heavy duty rubber. I know from experience for most of this.
