I'd like to see a photo and info on the kit, where to buy, price, ease of installation etc.BillsCamino said:FYI.. there are kits available to box your original stock "open" lower arms.
I can take a photo and post it here if that would help...
Mine are a little different than the method described...Mr Chevelle said:
True Brian but the inserts are formed to give better support around the sway bar bolt area.69boo307 said:Just go to home depot and buy some 1/8" steel, and box them in yourself
I don't think boxing will be noticeable or needed if you're not planning a sway bar, just make sure your control arm bushing are in good condition.Hughski said:I'm debating getting a set of stock boxed lower arms to replace the original open ones. Do they work well enough or should I consider something else? The car will be mostly a cruiser...no canyon carver or strip machine.
Not true... The uppers need to flex to be able to go through their range of motion without binding up. The bushings do not flex enough, so the arms need to have some flexibility. If poly bushings are used, and the arms are rigid, that flexibility has to come from either the frame (bad) or the axle housing (worse).chevfan_1 said:Box the uppers while your at it. No such thing as too strong.

They probably already know it, but they're making money, so they don't care.chevfan_1 said:So you guys can tell hotchkis their uppers are worthless and poorly engineered.
That's pretty-much right-on :thumbsup: I'm going to try spherical in all 8 pivots in the rear.Mr Chevelle said:A while back there was a long discussion about boxing upper control arms. I tried to find the post but gave up. I think it was about a year ago.
If my memory serves me correctly the discussion went something like this: Because of GM's 4 link control arm configuration something needs to flex when the differential moves. The best place for this flexing is the upper control arms. Boxing the upper control will eliminate it.
If poly-urethane bushings are used in the upper and lower control arms at least one rubber bushing should be used in each upper control arm, perferably the one in the differential housing.
The one acceptable place to use both upper and lower boxed control arms is drag racing because the differential movement is very limited. They even sell solid bushings for this type of use.
Some suspension companies like Edelbrock are offering upper control arms with spherical ball assemblies that allow the suspension to move freely.
Hmm...sounds like a good idea...Derek69SS said:I'm going to try spherical in all 8 pivots in the rear.
