I'm kind of shocked. They look like LSR arms. It was the only reason i actually bought them in the first place. But lonestar is telling me they are not lonestar. Thoughts on what they might be?
Basically im looking for replacement ball joints.

american star maybe??? Cant really see the bottom arm but I know the top arms from amstar and lonestar look close...
-
Just take all the measurements and hunt for it at FK bearings they should have a suitable replacement.

or go to Jegs or Summit racing...type in 3/4 in heim in there search and a bunch will pop up....They have really fast shipping also.....

I ran into a set of LSR copies once, they took the same ball joint. They were the same in almost every way other than you could tell the finished product was not quite as good, welds, finish ect. and the reinforcement on the lower was slightly different. They were not sport arms like what you have but they were standard travel, the rod ends up the uppers were the same on mine also. I'm confused by the nut welded on because all of my LSR arms were threaded through that whole tube even the copies, I distinctly remember that because I ran the jam nut on the inside so I could get it down to around 46" width. I wish I could remember who I thought made them because I found who I thought it was at the time.
-
Some idiot welded the jamb nut. I didnt realize this untill after i bough them and they sat in a box awaiting my build. Same guy that told me they are LSR arms.
-
Some people are ultra helpful aren't they. I think the ball joints LSR runs are a pretty standard size, I know they get them from a company called Frapco which supplies tons of companies. I used to buy the dust boots from LSR for all my different brands because the ball joint was pretty standard as long as it had the groove for the spiral ring. I hated the caster they set those things at back then so I always went for the adjustable ones, I did chop some up and make them adjustable by adding washers to the rear it's how JD does theirs pretty much. Those things are probably twitchy at high speed in rough stuff, lots of them only ran like 3 or 4 degrees.
-
Three companys that come to mind that use that style of ball joint are:
American Star
Full Flight
Fire-Ball Racing
They look closer to the Fire-Ball a-arms. Is there any webbing in the Lower a-arms?(http://i1085.photobucket.com/albums/j438/TRX250RACER/20131107_233358_zpsjriftt52.jpg)[/URL]
-
No webbing. I will take more pics tomorrow.
-
I don't think i've seen a pair of Lonestar's with heim joints as opposed to standard ball joints. Now i've seen LSR's with heim joints where they mount to the frame
-
Any idea how old they are?
-
burugard?

-
Well Heres what i have seen.
Full Flight - uses adjustable frame mounts and has a cross bar right near where the arms mount to the frame.
American star has webbing around the lower shock mount.
Fireball - cant find any pictures.
I swear they look like LSR with heim joints installed. maybe thats what they are.
-
Dont think they look like burgards either.
-

I'm with Tbone. I have never seen LSR's with heim joints at the spindle, only on the frame side.
-
Well my point is its possible the heim joints are not stock.
-
I realize what you are saying. I should have also mentioned that the bends in the a-arms and the general construction does not look like LSR. Are they standard travel or long travel? I have had both from LSR and neither of them look like those.
-
They are standard travel.
At this point they dont look like any other A-arm i have seen. Im at a loss as to who actually made them.

They sure look like LSR to me, set on my daughters look just like them, except hers has himes on the inside upper arm.
Those heims worn out ?.

On the right side the top is stiff, and the bottom is loose.

look like these will work

-
I wonder if they are denton a-arms.
-
If you go to this image of the closed ebay auction and zoom in they look just like these as far as i can tell. I even have the copper/brass inserts where the a-arms mount to the frame.

they look like laeger/burgard arms to me. I thought lsr usually had some webbing on the bottom a-arm. the previous owner must have wanted to convert from the style of ball joints originally used to the heims and thus welded the jam nuts on to mount the heims too.
my pesos :stung:
-
Na the arms are threaded on the inside as well. I had to grind one of the jamb nuts and break the weld so i could back it off and adjust camber. man i hope that they arent whats holding it.
-
That top a arm sure makes it look like lsr to me
-
the denton arms the balljoints go all the way through the bottom arm with a nut on the end... From the pics doesnt look like yours do...
-
And the bottom arms are completely straight, no bend. I was sure they where LSR. Maybe they are just upgraded with Heims. I bought a pair of heims, so we will see if they fit.
-
they look just like mine minus the heims.. I know for a fact mine are lsr...
-
can you post some pics.

can you post some pics.

I had that pic on my phone if it helps... Kinda hard to see the arms though

This is who copied the LSR arms that I found, I'm sure there are many others that have long since disappeared. You have the sport style the ones they are talking about are the old standard travel ones and I don't think they sell them anymore. Burgard arms are not built like these, they are not his.
-
Could it be they're not 250r arms? They look a lot like the lsr arms I had on a kfx400 other than the hiems.
I thought the Janssens had a bent lower arm like the Rolls.
-
They bolt up perfectly. I assume they are 250R arms.

Might be far fetched but I live near the Arens brothers and have talked to them about all sorts of things from frames, swingers, stems, to arms. While frames are most common they have made a few other things that are not wide spread. Just maybe. They do things alittle different like the lower steering stem mounts so maybe they did a heim joint?
