That may be true, but that doesn't mean it hasn't happened. When suggesting these types of mods to ones suspension components, I feel its best to advise overkill rather than taking safety concerns lightly.

thanks, i would rather sombody suggest me to do it overkill than for it to not be enough. also those a arms dont look to bad, but mine are a different style, and that opening probably wouldnt work for me.

here is how i did mine, i did not run the "bucket" as deep as you did. Let me warn you about this design. I was running these arms and hung the truck up on a man hole cover. It did hardly any damage to the arm, but totalled the truck. Do not run your truck low, keep it at a safe ride height. I am lucky to be alive. These arms now reside in my trash pile and now have a porterbuilt dropmember.

thanks for the info, i will also not be riding to low at least for a while as i do not have compressors, tanks and valves yet, it will be ran on shraders untill i can afford it, also i would like to get a pb dropmember but that is not in the budget at this time

Ya know, if you were to slightly modify the filler pieces to also be utilized as skid plates then if you did hit something the lower arms would slide up over it rather than get hung up on it....

Again, just a suggestion.

well i was trying to make a couple of points. when cupping the arms it allows the truck to lay crossmember. when plating the arms like i did it made them stronger then any other part of the suspension. so when i had the truck about 3 inchs off the ground i was approaching an incline where the man hole cover was at. the a arm hung up on the rolled lip and stopped the truck. i went into the windshield. the control arm is tied to the cross shaft, the cross shaft is tied to the crossmember and the crossmember to the frame. the frame was the weakest point on the truck. bent it down about 6 inches and out about 4. it was not pretty. the dropmember is the solution because it allows you to drive it where you want it without the suspension hanging low. the a arms are going to be the lowest part of the truck without the dropmember. just be careful. still paying the hospital bill for that one.


you are going to want to drive it low, that is why you bagged it. this is why i really discourage your design. i would leave them flat like i did. but we know now that it is still not the solution to geeting these trucks low.
