End-Links with Spherical Bearings, All in Stock

[PolTec Inc]

For the people who have pink 6 piece with that little pink box. If you sandwich a big (1 inch diameter) washer in between the endlink & pink box, does that do anything to reduce the stress on the pink box? or even weld it on the pink box surface , so that act like a reinforcer?

If you look at the control arm bushings they have a metal tube inside the rubber bushing and the outside diameter of that tube is much smaller than the OD of the washer so, by adding the washer, you will not increase effective mounting surface of the "box" signifficantly. Besides, this is not the place where people experienced failures.

I think STI should of boxed off the top of the end link mount for re-inforcement. They probably left it open so you can access a wrench in there to mount and dismount the end link.

This would help but I do not think that it would be sufficient when using 24mm sway bar. I think that I saw failures of the "box" with 22mm sway bars already.

yeah so like, I installed my Poltec adapter boxes (the billet aluminum things pictured above) and OMG. They fit perfectly, work extremely well (they feel wayyy better than the Kartboy I took off for the install) and they also took a coat of STI Pink very well

Thanks Poltec for the awesome job with these! That was money WELL spent!

my roommate has been "borrowing" my camera for over a week now.

I'll get a pic as soon as I can.

Thanks Poltec, great product. I replaced my stock endlinks which one fo them broke in half and yours are much stronger. However, I noticed that they tend to lean towards one side, either towards driver side or passenger side instead of staying straight. Otherwise the car handles great.

bwco, I sent you PM.

spankaveli, your order will ship today.

Regarding the "pink box" replacement, here is the picture of the prototypes that nhluhr will be testing soon. If possible, I would like few more of you to test them as well, send us email if you are interested.



The box is made of billet aluminum and the end-links are oversized versions of our USDM STi end-links.

hey poltec, i wonder if the final product will be the same thing as these? or we'll have the shiny silver color end links same as what your website listed?

one more question, i found some of these (golden color) endlink shell (without bearings and stuff) selling from a home hardware store here in Canada. So, the endlink you guys selling are different from those that I see? I'm totally a noob here, i thought i would like to ask for more details in these link.

Thanks in advance

Is there a noticable difference in noise/harshness with the full bearing vs the bearing/bushing endlinks?

Do the endlinks make any more noise than conventional bushing endlinks?

Thanks,
Dave

Thank You, I am glad that you like them, regarding the movement of the sway bar, little movement is normal with links that use spherical bearings since they eliminate restrictions that links with urethane/rubber bushings impose.

Final versions will also be gold and we will be using these components for the USDM STi applications as well. We decided to do that as a result of the recent problems with Cusco bars, these golden links are actually about 50% stronger than the silver links.

You might experience slight increase in vibrations as your suspension works but it will be only a fraction of what performance tires or stiffer springs would add.

Links themselves should not make any noise but may bring out noise that your sway bar makes since you will no longer have rubber bushings. If you are concerned about it, you may try our combination links that have one spherical bearing and one urethane bushing.

nhluhr,

Thank You for the pictures, nice paint job BTW.

Compared to STOCK yes, but I had GroupN bushings on there before and now it's actually a little more "supple" over bumps. I attribute that to the bearings actually moving instead of the ultra hard rubber GroupN bushings just deflecting.

Even though it feels smoother, imho, than GroupN bushings, the rear still feels much more located and precise. You can ask my STI-driving roommate how controllable my car is. I'm able to toss it around freeway cloverleafs and easily balance between throttle and lift-off oversteer. It doesn't snap out of control like it did with the stock stuff... It just keeps itself right where you want it.

You should take up sales. I'm going to order a set to replace my poly bushing endlinks, not having any extra binding in the bushings sounds great.

would i notice a big change in my cars handling by getting these endlinks?

[PolTec Inc]

AK_2002_WRX,

The difference in handling will depand on the size of the sway bar that you are using, the bigger the sway bar the bigger the difference that you will notice, plus you do not have to worry about them braking on you like the stock links could.

The links with spherical bearings will give you the biggest difference, since they will always keep their effective length the same unlike links with urethane bushings that will always compress more or less depending on the design.

Ans with our links you do not have to worry about bearings wearing out or rusting since we seal them with rubber seals that keep the grease in and water and dirt out, no other links with sphearical bearings have that feature, not even Perrins and they sell for a lot more.

[AK_2002_WRX]

im usin the stock sway for now, and i am planning to get a cusco. i just wanted to put them on part by part to see the difference. is the vibration and harshness a lot more noticeable?

also i'm going to order your solid endlinks with the spherical bearings tonite

thanks a lot!

After installing Poltec's endlinks, I didn't notice any additional vibration or harshness.

ditto, only thing i noticed was the rigidness increased

Just ordered. Great idea to use the PayPal linked checkout.

If you order both fronts and rears together you save 6 dollars on shipping! (total 10 instead of 16)

Cant wait to get them. They will be replacing whiteline units.

Sorry PolTec, one more question... actually two...

I'm concerning about the ball in the housing. Since the stock endlink has a closed black steel housing that hide the ball inside the housing. Now, these endlinks came with an exposed balls. So, when we're doing autox or on track, is there a chance that the balls being pulled out? In other words, is there a thrust rating on the balls? Does it handle side loads? Or my concern is totally nonsense?

Thanks for your reply

[PolTec Inc]

bwco,

Those are good questions and we did take them under consideration while designing our links.

1. The stock links do not have the ball completely enclosed, there has to be opening for the mounting bolt that you use to mount the links.

2. The balls in the links do not experience any axial (sideways/thrust) loads since they always align themselves with the forces that they are carrying so that they only experience either tension or compression. To illustrate this, imagine holding the bottom screw of the link horizontally and pull on the top screw sideways, if you do that, the link will tilt with little resistance since it is going to swivel around the bottom ball. No resistance will be felt until you reach the allowable travel, however, in real life, the links will never reach that point because the sway bar and control arm constrain this motion and our links are designed to operate in this range plus some margin of safety trough use of special spacers that allow for maximum swivel.

3. Bearings that we use are not thrust rated; however, they do withstand about 500lbs of axial loads.

In other words, I do not think that this should be a problem with our links and we have not had any instances of that happening.
