QA1 Rod Ends - Chromo vs CarbonSteel for Wheelin

[CaptainInsano]

I am looking at the rod ends available and trying to figure out which ones to get. Buying the replacments for last times carnage, plus two more for spares. After much investigation and actually one of the pics from the day, the reason the end failed was do to binding, ouch. The drag link was up against the spring, can see the gouge in it. Put a shear load on the rod end and snap.

The ends are 5/8" - 5/8"-20.

I was thinking the Chromoly except the Carbon steel would bend a bit before failing correct?

I think I just answered my question...

XM Rated at 17,955 lbs

vs

EXM Rated at 7,364 lbs

vs

PCM Rated at 18000 lbs

Just because mild steel has a lot of room for plastic deformation before failure doesn't mean its stronger than something that didn't yield to begin with. Its like the G5 to the G8 bolt arguement.

Do you gain more strength by going bigger? For some reason 5/8 is seeming small to me. What kind of forces are you dealing with the hydro steering and bigger tires?

[CaptainInsano]

I fixed my steering another way today, no need for the rod ends... :D

it's ghetto, but it works for now...until I get the coin to do full hydro the right way.

just need to weld up the 14 bolt gov bomb and I am ready to wheel again!
