Inexpensive adjustable rear lower control arm

[maslin]

Yes, heim as in Kleenex, band aid, etc.

Heim joint, for your race car.



Spherical bearing (or bushing) for your 1988 Mercedes, BMW, and a million other factory fresh cars.



Elastomer Whiteline bushings



Stock inner bushing.






All of the stock looking LCAs with slots and cam bolts use a spherical inner bearing. The Whitelines replace that bearing with elastomer bushings for STX compliance. Heim joints (as everyone in the world refers to them as) go on race cars.

We're talking about lower control arms. They are rated to be lower control arms. Except for those $25 Chinese child labor rips offs. Those probably aren't rated for much.

Nope. That is a rod end. Possibly made by Heim, or one of a bunch of other manufacturers. Aurora doesn't sell Heim joints, they sell spherical rod ends.

It's not an escalator, it's a moving staircase!

The $25 China arm you seem to be defending has the joint you are arguing against, if that didn't come across.

My understanding is that OEM uses a plain rubber bushing/sleeve on the inboard end, not a spherical joint, and that the cheap control arm also uses rubber, which is what I want. If that's not the case, then you are correct in that this is all academic. Still, regardless of what is used at the inboard end, the $25 arm does have the eccentric bolt and washers and the tabs for them to ride against, so it's still a relative bargain for what functionality I'm looking to gain. Since no one has apparently used the Ultra-Power brand, I guess I'll be cutting edge again. lol

The OE arm uses a solid rubber bushing. The SPC/Moog/8 other brands use an enclosed spherical bushing, that is why they are illegal in STX class. The Whiteline arm is the same arm, with the spherical bushing pressed out and solid "elastomer" bushing provided.

The ultra-power arm appears to be a replica of the SPC part, spherical bushing and all. Just noticed the picture, those cam plates are going to be a bitch, flat sides on a eccentric don't work very well.

Moog/SPC/et al




Ultra-Power!

the SPC arms work fine for what you want to do and will last you a long time.

I mentioned the bearing because others have already pointed it out... it's not legal for STX classification. Whiteline will be closer to stock + adjustment with minimal possibility of play.

Welp, I took a gamble and got the MegaPowerrrzz... They do use a spherical bearing(possibly Heim branded?...lol) rather than a sleeved rubber bushing like I wanted but I couldn't find any other options, plus the price is definitely right. Installed them over the weekend and got the car aligned and was able to easily get the numbers I was looking for. We'll see how long they last; might see if I can pull the rubber boot back a bit and get some extra grease in there...

FT86Motorsports Canadian branch have a nice deal on Blox LCA's.
And cheaper than the Whiteline units and pretty colors. Here is a link to the red ones. Not sure if their US shop offer the same pricing.

EDIT: actually, they don't even list them on their US site. The link above is CA$. Your dollar is worth 35% more so even greater savings.

I just got a pair of coilovers for my car and found these UltraPower LCAs on RockAuto for much cheaper than the Moog’s or the SPCs, while looking fairly similar (I assume it’s a replica as others have stated).

I haven’t found much in the way of info on them other than this thread specifically; so I’d love to see how the UltraPowers been holding up for you? I don’t mind spending more for the Moog’s, however at $34CAD per arm vs $120CAD, I’d take the significant savings if the product holds up well.

They seem to be holding up as well as any other stamped steel arm would. I was able to get the alignment numbers I wanted, they installed super easy, they haven't fallen off the car...not sure what else to say?It's not a bling part, but considering i DD my car in the rust/snow belt, chassis bling is kind of pointless. It does what I wanted for short money. I'd buy 'em again.

The cheapest way to do this is with a pair of 14mm camber bolts. I have no idea why this isn't common. It's been working on my car for years now.

#Calum On the rear??????

#JBezugs I had issues with designs typical to the blox seizing and chewing out the thread. Maybe their materials have improved.

Same

downside is not a lot of adjustment. +- .5~.75 degree adjustment for $30 bux.
