Lets get this right out in the open, my math is not that great but I calculate these are at least 4 times stronger than stock factory control arms for the Jeep JK, TJ, LJ & XJ! The factory arms are weak, too short when adding lift and need replacement. I dont think you will bend ours and there are lots of advantages.
These have 1.25 Heim joints for the lowers and 7/8 Heim uppers. The Heims allow for more than twice the travel (36 Degrees) of the factory bushings (~10 degrees).
Both our heims and bushings are easily replaced, you do not need a press to replace them.
The Upper arms are not a simple butt joint, they are seriously reinforced where they meet the housing.
The tubing of the lower control arm is 2 x .25 wall DOM, the uppers are 1.5 X .25 and made to take any hit you can throw at them.
These are all Jig Built by Humans (Not Machines) here in Loomis California With steel made in Alabama or Chicago.
