Im going to make 2 sets of traction bars for myself this year. Trying to make them for as cheap as possible and basically the only thing Im going to have to pay for in the heim joints or whatever I decide to use if there is anything else.
Do you really need 4 of them or will 2 suffice with a solid mount on the control arm?

Are there any designs or materials that are better than others? Squeeks and such

Any cheap places that sell them?

Thanks guys

 

Also curious if the way they are threaded matters, left and or right seems to be sold

I dont know how they are adjusted at the radius rod or what adjusting does so i dont understand

Is 1/2"-20 A good size for these?

 

If its an EF chassis type DO NOT use 1/2. GO bigger. If its an EG/DC/EK type the 1/2 will be fine. You need right and left threads so you can adjust them on the car.

 

Don't buy cheap rod-ends!!! A rod-end breaking is not ok. Aurora is the best around for the average racer. www.hrpworld.com Talk to Mike Eddy!

Go check out speedwaymotors for nice threaded rod but I don't really like their rod ends. I went with some from McMaster when I built my 4 link and panhard for my old Corolla and they held up fine. Don't buy cheap heims if you value your life. Those snap and it won't be pretty.

 

Look what you can do with heims. I used (6) 3/8th heims to make this hood open almost as far as it did stock.

I don't care if it helps for mad downforce. It's mexi-retarded :1

 

Any particular model of Aurora end I should be looking at?

 

To be real honest. I have no idea what a track bar has for forces. I have never worked with one before. The AM-T and AB-T rodends are pretty good for most applications. If you have the extra money then go with a more $$$$ rod end. It is better to over build the first time, it's cheaper then breaking one then replacing them all.

1/2 heim can hold up a small bridge, they are strong if you use them right.

Would 1/2-20 suffice?

Theres some cheap ones on ebay

Also, does my welding a nut onto each end of my new radius rods work ok, or would that be taking a ---- load of force?

I BELIEVE that tubing I took from work is almost 3/4" ID But 3/4" heim are EXPENSIVE it seems
