are 3/4 heims big enough for a panhard bar on a stock YJ with 36s-37s when looking at 3 linking the front? I notice a lot of the panhard brackets are designed for 2 inch spacing. I was planning on 7/8 heims but I already have spare 3/4 heims. I'm sure they are too small for the 40+ tire rigs.

I run poly on my trac bar and 3/4 on my steering I run heavy 38.5 xmls (145lbs 16x10 steel wheels)
3/4 are fine but heims wear out like every 6 months at 30 each it gets expensive..might increase their life with a styabilizer or get off my butt and put my ram assist in.
 
3/4 heims on the panhard on my buggy with 1 tons and 42s. They work just fine for me.

if you buy quality heims they will last a very long time.

3/4 QA1 Chromo only last me 6- 12 months. I keep loosing/damaging the teflon liners:confused:

Are there any beter possibly w/o liners?
 
rsmx10t. thats an fk part#. they will last for years. they also have high masalignment, .75x.75, .75x.625. also have larger sizes. .75 joints are adequate as novacayne said just be sure to get quality parts. the tefelon, kevlar liner is the key to long life.
 
A 3/4 will do fine. QA1 are heavily over rated. Midwest Control and Ruff Stuff are actually pretty good joints. 75% of the heims come out of the same building anyway. Bushings on a trac bar are a waste of time in my opinion, that's one area that I don't want any deflection what so ever.

I know you do alot of steering systems, how long to heims usually last? I run heavy XMLs (38.5x13.5) on 16x10 w 2.5 bs with a weight of 145 lbs each. I know I have alignment issues with radius arms. Could the alignment, tire weight and no steering stabilizer be causing the heims to wear out premature? Also is there realy a big difference in the steel ones from CV products (only ones available) and the chromo from Qa1? I dont understand why Nascar and drag cars use the regular steel ones and not the chromo....
 
You caught me in a talkative mood.
We are trying new brands all the time. The average heim is going to last a year or two before it has enough play to become noticeable. If you beat the :poop: out of it often it could be a couple months. So far i've found that the high end FK's last the longest and are the tightest but they are wicked expensive.
We don't use 3/4 heim's on steering or in general anymore unless its a D30 or something small and they want a little stonger steering on the cheap. We use all 7/8 stuff since its only a couple bucks more. We have a lot better luck and longevity with that.
I don't know about the nascar stuff or the steel joints. I feel that steering is no place to slack on quality so we've always used the chromo.....there may not be that big of a difference, i'll do some research on that.
Those things you listed probably don't help matters much but fighting big out of round, non balanced bias ply(I know yours are radials) heavy tires sure don't either.
Steering geometry will definitely effect it if you have horrible angle and load the joint weird. Steering stabilizers are bandages for steering problems, they do smooth things out but you have to remember this is happening at the knuckles, not at the steering wheel so tire balance is going to have a lot to do with it.
Just try to keep them clean and shoot some WD40 or something like that pretty often and that will help give you a little more life. The bottom line is its a consumable like TRE's, they wear out.

another thing you can do to help protect the heim against wear from dirt are these heim seals from Baker precision. Someone else might have them as well, but this is the only i place i have ever found them. They also have boots that slip over the entire heim.

^ Thats pretty cool, I've never seen those. The only thing about boots is what they keep out they also keep in.

uh-oh. Does that mean you might start stocking the "seals" it would be nice for someone to start selling them around here.

Just kidding man. You make a very good point about whatever they keep out. They also keep in. I like the evo Heims bc they are greaseable and rebuildable. But man they are pricey.
 
Yeah I have one of those Evo heims here but at a $100+ a pop they aren't that nice. I might try to drill a couple heims out in the shop and put a needle type grease fitting on them and see how they do and if it helps at all. You guys let me know what you want me to stock and Ill have it here.
 
We have 3/4, 7/8 and 1.25 HEIMS in stock Just a 3/4 HEIM is $15 bucks chromoly heat treated and cryo treated suppossed to increase life there ruffstuff. and we have had good luck out of them.
 
Thanks for the plug Chase.

But you bring up a pretty interesting subject. Cryogenetic treatment does amazing things to Nylons and Teflons. Google it, the gain in durability is 2-400% over non treated joints and at $48 for a 1.25" Heat & Cryo Treated 4130 Heim is a steal.

I noticed another thing mentioned here. Joint width with misalignment? Several people mentioned 2" as the width? We make our 1.25" heims 2 5/8" overall with misalignment, that is and has always been the standard width...If some company is telling you otherwise either they have no idea of what they are talking about or they are simply trying to sell you something else.

We do make all of the 7/8" & 3/4" spacings 2" overall, you get full misalignment (34 degrees) in 2" spacing with 1/16" to spare. A 1.25" heim goes to full misalignment in 2 5/8", any other width would either waste valuable axle space or be too narrow.
