I think Nitros are even cheaper than the Blackhawks right now on Bumper Superstore. I guess its nice to just but whatevers cheapest if theyre all the same.

I will probably need to replace my old style Nitro UCAs soon and have been looking at the Blackhawk/Dobinson/Nitro option. I reached out to Mill Creek Overland who is a US supplier of the Blackhawk units and he wasn’t totally sure since he said they haven’t yet had to replace a ball joint in their shop on these arms (good sign), but he though it was the 100/200/GX unit which reassured me since it’s probably a better part than what’s in the Tundras. FYI the Blackhawk units are super cheap compared to Nitro and especially to Dobinson.
