UPPER CONTROL ARMS

[penner]

So, while I was replacing the rear shocks on my 2020 Trail Boss with Bilsteins I had my mechanic do a check on the front end.Turns out the control arm ball joints are shot and since the ball joints aren't replaceable I have to buy upper and lower arms. Apparently this is a problem with the Trail Bosses. Truck only has 110,000 km so I was kinda surprised. Thinking I would be best to go to an aftermarket upper arm that would accommodate the 2" lift. Anyone have any suggestions?

I have a 20 Silverado Z71 and would like someday to get a 2" lift. During my research I have seen these mentioned many times and they seem to be a popular option.

Ball Joint Upper Control Arms

Dirt King Fabrication Chevy Silverado / GMC Sierra ball joint upper control arms (UCA's) with polyurethane bushings. These upper control arms allow for 1" of additional wheel travel and up to 3" of lift with 35" tires.

As far as the LCAs are concerned, I think the lower stock option would be good. I think the only reason to replace these is if your looking for more travel.

Again, I have not used this product, just some ideas for you. Let us know what you end up going with!

After contacting a few of different shops I decided to just replace the UCA's with factory ones. They said if I was going to raise the truck any more than the 2" factory lift then I should consider it.
