Yes, welds aren't known to improve durability.

This is actually false. When a weld is done correctly, it will be structurally stronger than the metal welded on. Essentially you're not only heat treating that metal, but adding alloys to it, thus increasing its sheer strength. Where welds run into problem is if the person welding them doesn't insure against contamination or pores in the welds.

True, but you have the human factor. If the weld is a little hot it undercuts the joint, a little cold and you don't get the penetration. These guys use what wall thickness to build control arms? And you seldom see gussets. There's very little info and tons of room for error. I've seen some where they talk about .043 tubing. Welding a thinner tube to a thicker ring what's the penetration without x-ray????. If it's .080 wall you don't have much holding it together when you have a 3k car hammer a pothole. Most of these parts are marketed "use at your own risk". So the liability is on whom? Seldom you see a detached wheel in a collision with oem stuff, but I have seen a few broken aftermarket ones from street use with no accident involved. If they're using cro-mo tube the properties in the HAZ can be changed/embrittled if they don't normalize the part after welding.

Yeah, that's why you have to do homework on the company. And why I can't stand AJE or Magnum force, too thin, crappy welds and tons of public evidence to their failures.

When I was doing my research on whether to go RMS , HDK or Gerst, this was one of my concerns. Carl at Gerst calmed those concerns with tons of evidence as to the quality of his kit, he personally welds each one and each is tested for strength and quality. Not to mention dirt trackers, drag races and road racers have been using his. There's videos of cars with his kit launching into the air and coming down hard yet the suspension holds up. If a driver can launch the car hard enough over a huge hill and land hard enough on the front to drag the k frame and the controls not break, I'm convinced. Plus I know the wall thickness on the GTS is the thickest currently on the market. Now would I run anything else? No.

Has for the liability side of things, under federal law, to be marketed for highway use, it has to be DOT approved and meet NTSB standards. Most companies outside of automobile makers can't afford the level of testing to get that stamp and would require a huge price increase in the parts. That's why pretty much every single aftermarket suspension piece, OEM style or complete custom like the coil over kits, all say in the fine print for off high way use only. So the liability would fall onto the customer unless the customer could prove the company knowingly sold a dangerous product and was negligent in design or construction.

Ok, insurance salesman hat is going back on the shelf lol
