Haven't installed a set myself, but we've sold over 1,000 sets over the past couple of years with minimal drama, if that helps!
The SD hinges are SUPER beefy, and look very well-built.
Our hinges are a bit smaller, but still feature steel hinge pins riding on bronze bushings, they use 1/2" steel for the hinge arms, and are generally much stronger than the stock hinges most vehicles come with.
It's really up to you whether you need the extra size/ strength of the SD kit. I haven't seen ours fail, and I've sold them for some pretty heavy doors (60s cars, 60s and 70s trucks, etc.)...
But again, my opinion MIGHT be a little bit biased- I try to leave that out of my posts, but it happens!
