I vote for the heim joints as that's what I'll be getting.
Even if it was a poly/heim combo it would still be better then what you have.

He wants a lca that will articulate what would you recommend Craig? What I mean by this is does the lca matter as far as tubular or boxed or brand?

I heim joint on one end or both would work fine. The amount the arm has to flex is extremely small. Full stuff on 1 side and full droop on the other in an fbody will only have the axle cocked at maybe a 10 or 15 degree angle.

Well the stock LCA with the rubber bushings will themselves flex. Obviously that works fine for a driver car but for a more spirited application (like we all want) a boxed or tubular LCA is needed to tighten up things. The problem lies in the Poly bushings, with their limited amount of movement, where as the heim joint while still being soild enough to aide in putting the power down has a better range of articulation. As Joel said before, the poly/poly setup works great for straightline stuff but falls short for a handling application. Before the heim joints became available I was looking at a Poly/Rod end combo. The Poly on the Frame for better noise control and the rod end on the Rear for better articulation. One other nice thing about the Heim joints is I heard they are rebuildable.
I've been using UMI parts myself and think they make a great product.

I agree but it's not all the swaybar either, springs and shocks help aswell.

[JoeliusZ28]

craig do you know of a one-ended heim LCA on the market? seems like that would be the optimal setup as you say.

Off the top of my head I think UMI sells one but it's an adjustable style.

Edit found it.

I have the Spohn rod/poly units on my car...it's the way to fly for a car that see's alot of street duty as well as track.

[JoeliusZ28]

I also made up my mind on this today:



It worked perfect but good riddance.

Is that your AC system? Did you ever think of a price for it?

[ThreeHonks]

too bad we couldnt remove the heater box assembly too. its impossible to do it with the engine in the car unless you want to take the dash off

I dont know about you Joel. But for me to sweat my ass off in a car it had better be 3200# or less with driver. Are you weighing this stuff as it comes off? Any guess as to current weight reduction? Oh, and do you have subframe connectors? Eric L
