sg30721 Posted August 9, 2005 Report Posted August 9, 2005 Are there any places that make hiem joints that fit Laeger A Arms as a direct replacemnt for the ball joints? Is there a universal size most of the arms use? I know alot of A arm kits out there come with hiem joints now instead of ball joints. Quote
MonkeyBoy Posted August 9, 2005 Report Posted August 9, 2005 Laeger ball joints are the best out there. Don't waste your time converting to hiems that are more maintenance and weaker. Usually when an a arm runs heims, they go to a much larger heim. If you replace yours, they probably will break. Quote
sanddragon2004 Posted August 9, 2005 Report Posted August 9, 2005 dont know where your getting your information from monkeyboy? but heims are like 6 times stronger then a ball joint. at least the ones we use are. maintenace? a spray of wd40 is all you need on them. Quote
MonkeyBoy Posted August 10, 2005 Report Posted August 10, 2005 In the direction that they are supposed to operate. They were never designed to be on vertical and horizontal shear point. They stress where they enter the arm. Both back and forth, and up and down. Ball Joints were designed to be pulled all directions from the outset. Quote
racer Posted August 10, 2005 Report Posted August 10, 2005 (edited) MonkeyBoy is correct. Heims are meant to be pulled radially. However the way they are setup on a-arms the loads are placed axially. This means that you must look at the radial load capacity and figure that you will see a 85%-90% (depending on the quality of the piece) decrease in the axial capacity. BTW: That info was taken from The Chassis SHop catalog and is for Aurora brand rod ends. Edited August 10, 2005 by gimmeabeer Quote
sanddragon2004 Posted August 10, 2005 Report Posted August 10, 2005 I guess, that is why ROLL, WALSH, JANSSEN, ATV four play, DENTON racing, Herman racing, Sanddragon. All run HEIMS? cuz they are weak design? Quote
racer Posted August 10, 2005 Report Posted August 10, 2005 no thats not it at all. its like he stated: You will find that these arms were deigned for Heims from the start and use a larger size than would be necessary with a ball joint. its not that they inferior. its that they are being loaded in a fashion that isnt there strongest point. so to compensate a bigger size is used.

MonkeyBoy Posted August 11, 2005 Report Posted August 11, 2005 The only place that they are safe is on the top arm. The load isn't as much on the top arm (why Yam could get away with alum upper arms on the YFZ). Also the load on the upper a arm is on a horizontal plane, rotating on the lower a arm connection with the spindle. Different loads entirely. I haven't studied everyone, but Roll will not use a heim on the bottom. Ball joint or uniball. Quote
sanddragon2004 Posted September 23, 2005 Report Posted September 23, 2005 To date, We have had zero failures, due to a heim joint breaking, i think if you look at the heim joint we use up close and compare to the ball joints out their you will see why. very heavy duty chromoly joints. Quote
sanddragon2004 Posted September 23, 2005 Report Posted September 23, 2005 Actually Roll was using a lower heim joint on their arms, and is now using ball joints. Why? could be the pending patent owned by fireball racing on them........ Quote
MonkeyBoy Posted October 4, 2005 Report Posted October 4, 2005 On which arms? The 250R and 400 EX was uniball, the Yamaha arms have all been Warrior balljoints. Leaves the LTZ/KFX. Could also be a move to a better design. Roll has been around much longer than Fireball. A patent doesn't mean you were the first, just the first to run to the government and fill out the paperwork.

Justintoxicated Posted October 4, 2005 Report Posted October 4, 2005 (edited) yea still with balljoints. I got some crazy super Heimes/Uniball on my custom creations A-arms, way stronger than fireball heimes from what I have been hearing. Probably much stronger than any ball joint also... Then again they are basicaly some kind of modified Heim Joint to be use on A-arms. They are HUGE and very Beefy, and the joint body is much thiker than a typical heim that looks like it might pop out if worn down. Good thing about balljoints is that they are sealed and keep crap out that would wear down a cheaper heim joint. Edited October 4, 2005 by Justintoxicated Quote
sanddragon2004 Posted October 5, 2005 Report Posted October 5, 2005 Fireball been around since 85, Fireball building heim jointed a arms for about 7 years. Custom creations started by kevin formerly a Fireball employee. Quote
sanddragon2004 Posted October 5, 2005 Report Posted October 5, 2005 Stronger then Fireball? take a look at the banshee/raptor heims they are identical. Fireball been making those arms for years. Must not be too weak if Janseen racing/Denton/ATV fourplay/Sanddragon/many others run them? Quote

FYI/ the R&D that went into designing those very $$$$$$$ Edited October 5, 2005 by sanddragon2004 Quote
