Initial review
I am going to update this review a few times. Cuz the problem with reviews is people review when they look at them and then something happens and I never update it. By looking at them. It looks like the ball joint is the same exact size as the factory ball joints as for the bushings. To me that's important because they can be changed easily. I'm going to Mike them later and we'll update that. I bought these my main concern was being able to get new ball joints and bushings in the metal being solid. Cuz you're still saving money versus $500 for rough country or so on. They look sturdy they look solid. I will periodically update this review as time goes

Bad parts very bad
This product is bad. I put it on my 2500 germax. Crew cab only had it for a few months and the upper ball joint popped out of its socket, causing multiple damage to the vehicle and the suspension. It's a good thing. My son was not on the highway. When this happened, a lot worse, things could have had happened. Or he could have been killed.

Ok
Works... looks nice... but the bushings are squeaky and annoying .. sounds like dry ball joints at first but it's just the bushings...

Buy them
Ordered a set for my 2004 Silverado 2wd with a 7” fab tech lift. These things are beefy. Haven’t installed them yet but they look very well made. The ball joint doesn’t have a grease fitting so I’ll be ordering some moof ball joints to press in UPDATE: I’m an idiot. The upper cap on the control arm comes off and the grease fitting to grease the ball joint is under it

Upper A-arm swap
Bad description, rub inside of rims, 22 in stock rims. 2017 cheverlet silverado. There great other than they need to be knotched at point of contact on upper a-arm.

1.5 years going strong
They have been installed for 1.5 years, 25k miles, and they’ve been great. Upon installation I greased them until it was coming out of the boot around the ball joint. I’ve added a little every 6 months or so. They’ve been good for me so far. I semi regularly tow a trailer, so I do apply more weight than just the truck, still no issues.

Absolute junk. Lasted 10 months and the ball joints came apart, lost the wheel, destroyed my lift, cv, etc. no warning, if you value your truck and life.... But the more expensive ones! Should be recalled.

I purchased these control arms for my 2018 Silverado, this is my second time ordering lift control arms for my truck, first ones did not last any longer then 2 months, when looking over the new set I have gotten we looked over everything! we have noticed the size of the ball joint is wrong! This is why everyone keeps blowing the ball joints on these trucks! If they would of came with a sleeve there would be no problem, but the fact that they are smaller when tightening jt all the way down they are not tightening until the control arms hits the spindle, then from there all it does is put pressure pulling the ball joint because the more you tighten the ball joint the more it pulls down forcing it to stretch out it’s seat, the more you tighten the ball joint with the control arm against the spindle your actually forcing the ball joint of off its seat pulling out out more and more with every tighten of a thread ! Which gives play In the control arm side the joint! With the arm against the spindle it also rips apart the boot causing you to loose all your grease!!! Not recommended buying for 2018 Silverado these are improperly designed for the year and model of the truck
