The ACDelcos for sure, but they are getting more difficult to locate.

You should not have to replace the lowers unless they got tore up/bent. Replace the bushings and ball joint in the lowers.

AC Delcos are impossible to find.

Lower ball joints are shot. Have to be removed anyways, so why not buy new arms? Aren't the lower ball joints like the uppers? I.e. they cannot be removed from the arms?

You do not have to remove the lowers to replace the ball joints, which are 100% available. Get a pickle fork. Watch the vids and read the service manual.

When you star looking for NOS items for 50+ year old cars or motorcycles, then thing get interesting. H3s parts can be tracked down, most of them quite easily.

ACDelco is a DISTRIBUTOR! Thousands of manufacturers produce for ACDelco to distribute in the blue-white-red box @ a huge$ markup to the customer!
I'm still driving my '07 on factory installed upper/lower control arms/ball joints/bushings and all still tight now. Whenever I find any play, I will replace the control arms, since they are CHEAP + improvement compared to +/-20yr of old rusted/rotted metal.
Yes, you can save$ replacing the ball joints and bushings but, will they hold tight?

Yeah, and they are made to ACDelco strict manufacturing tolerances and approved manufacturing quality control standards. Not only is the product (parts) subject to inspection verification, the plant they come from is as well. There is an economic incentive not to cut corners for approved suppliers because if they get caught, they will not be paid for the parts delivered and have to eat the cost and sell their inventory under a different or in house brand. How long would it take to package, store and sell 60,000 (you insert the part name) on the market to get back your investment?

Cheap parts are cheap because they knock off the GM designs with inferior materials and do not use the same QC protocols and/or tools so they cannot make GM parts, but they can make cheap parts to sell to whoever chooses to buy them.

I helped a guy install an H3 Moog Upper Control Arm that he bought. It served him well and was on the truck for the next buyer. Got no idea what happened after that. I do know some trusted people in the H3 parts industry that say they used Moog UCAs and they did not hold up over time? I have used Moog hubs and suspension parts on winter beaters over the years with mixed results. Some went on to new buyers, others I had to re-do far too soon. I will always look for ACDelco when available and know I pay for what I get.

Good luck, choose your parts however you feel comfortable.

Since I can get an AC Delco Upper LEFT arm only. RIGHT arm is NLA,

I went ahead and ordered MevoTech supreme LOWER arms and TRW upper arms (on sale/closeout) from RockAuto.

I have a GM/ACDelco Right UCA in my parts stash. Looking for a deal on a GM Left UCA to add to it.

Nobody mentioned the Michigan Metal Works option? H3 Adjustable Tubular Upper Arm Set
