it all depends on why you need shocks.
The notion that you only need one shock per wheel is not always the case, depending on what you need.
Leaf spring rear suspension needs to control axle tramp. Which is normally done by placing one shock in the Clockwise direction, and one in the Counter Clockwise direction. It is called "staggered shock" design. The Trans-Am 4 speed Mustang's got staggered shocks. Every Chevy pickup got staggered shocks. Dodge went staggered in 1994, and F150 got them in the lightning in 1999, and the rest of the F150's in 2004. So every major manufacturer finally got around to it. (less weight on the rear end, with more power)
I would rather have 4 Sensen Shocks (RockAuto for $4.12ea) staggered in the rear than a pair of anything in the catalog. Because I have power, I use power, and my rear axle hops a lot. And rock crawler springs LOVE axle wrap.
Up front, there's nothting that a single Bilstein 5100 can do that a pair of good 70/30 gas charged Nitro's can't do better. Or at least similar but for much longer. But I like my suspension firm, and overdamped. I am NOT looking for a plush ride. I do NOT want comfort and luxury in my Bronco. If I want a road floater, I'll drive a Town Car. I want confidence, I want the front end planted. BECAUSE I get a ton of compliance in my 35 inch sidewall.
If you have 4 link rear, totally different story.
So the valving in a 4300lb Bronco on 35' is totally different that the valving in a 4300lb Tesla on 295/35/21's.
If you are shopping for Shocks, there are three ways to do it.
1. Buy a set of fully adjustable multi valve, tuneable compression and rebound "tools" and configure them for your use case, and optimize them for your preference...
2. Buy a set of shocks from a trusted vendor that has already done your homework for you.
3. Copy something proven that works.
3a. Test drive that configuration in a similar Bronco, or solicit feedback from actual users that do similar activites and similar driving. Do NOT use feedback from bench racers, or keyboard warriors. You want feedback from someone (with video proof) that shows how it WORKS.
In 1998, I had an Electrical contractor doing a job at my worksite. He was an auto enthusiast, and was driving a 2WD Ford Explorer. He had installed a set of Edelbrock IAS shocks, (one per wheel) and he was raving about their performance. Recommended highly. One day I went for a drive at lunchtime in that station wagon. OMG. That guy drove HARD. We went to his garage, and without exaggerating, he had at least 10 sets of practically new shocks of various brands that he ran at the track for 1-2 days and discarded. (Don't judge a book by it's cover...)
If you have the mounts for dual shocks in the rear... use them, (or go staggered.)
