Rod end & DOM tubing choice for 4-link?

sen2two · 05-11-2013, 02:25 PM

I am planning to use 3/4 rod ends with 1.25 od x .125 wall DOM chromoly tubing. But I think this might be over kill. My car should weigh in at 1700-1800 lbs or less when completed and is an all motor car.

Could 1/2 or 5/8 rod ends be more than enough with 1.00 od x .125 wall chromolly tubing?

This is both a weight and cost choice. I know it will only be ounces saved here and there. But if I keep that mind set when choosing every single part for the car, it will all add up. And cost is always an issue...

Also, are chromolly end link really needed? or are the mild steel versions good enough with a car as light as mine?

For comparison:

5/8 mild steel rod end: Ult. Static Radial Load: 13,540

5/8 chromo rod end: Ult. Static Radial Load: 17,995

3/4 mild steel rod end: Ult. Static Radial Load: 18,810

3/4 chromo rod end: Ult. Static Radial Load: 28,081
