40* might be a bit extreme on those cv's. i ran mine with a max of 35* on my busa for 3 years. it does run higher temps at 35* where 40* will be a touch hotter. i have never tried 40* so i cannot say for sure. i lowered mine to 30* with my current motor. only thing getting them hot now is my down pipe lol
lance is right on the twist as well as bending moment. just for example.......enemy had lower a arms with a single piece made out of 1.5" od .25" wall 1020 dom. i mounted the shock close to center as you have done. i questioned if that 1\4" wall was strong enough waaaaaay back then! lol it wasn't, he bent it down apprx 1/8". so built new ones with a brace. now you have seen my current rear a arms with 2.5 fox shock mounted 40% up from carrier. i used 1 piece of 1.5" od .25 wall tube and 1.25" od .120 wall to make the lowers. recangle 1"x2" .125 wall tube was used as bracing. shock is mounted on the 1.5" tube with an extra wide ( 8" wide i think) shock mounts. the rectangle tube welds to the point to take the twisting moment. i say all this because mine is much heavier than yours. it has been fine for over 2 years and has been bottomed out a couple times. now having said that i also have a 3 legged lower arm so the twisting moment is support from both sides. could a couple pieces of rectangle tube in each lower for bracing work on your with current shock location?? i think so if you use a long/wide shock tab that spans ateast 3/4 of the lower arm and inner tab weld to the recangle. still cannot say for sure though. lancew what are you thoughts on that idea?

I will max it out at 35* to keep things somewhat in the safe zone. Maybe 36* to live life on the edge. LOLJustin
It'll just bend at the end of the truss. You're just moving the stress point. To overcome it with a truss the truss has to go from one reaction (think pivot) point to the other. At which point why even use the tube other than be a jig for the truss. The shock in the middle of the arm is the problem......Putting the shock on one side and the bypass on the other is a good idea to balance the load but the arm will still see twist if they are not even in the reaction force when the arm is forced up in suspension compression. Whether it's close enough??? all you can do is try it.
