Same category as traction boards, useful but more effort and hazard than I want to deal with. Most manufactures don't make sliders or bumpers that really work with high lifts anymore.
Yes and no, the notches are a gimmick. High lift is the worst jack to use to change a tire and that is what those notches are for. When offroading you need to be able to put the jack in the most stable location, while stuck (rocks, sand, etc) and not damaging the body when it comes down.StinkyFab has sliders that have notches for high lifts front and rear.
Personally, I hate Hi-Lift jacks and don't find them to be useful on the trail. They are dangerous, and difficult to use. I stopped carrying one many years ago. That said, I wouldn't call slots that make it possible to use one a gimmick. Without the slots there's zero chance of getting the jack to do anything on a ramped surface. We designed our sliders to be far enough from the body for good protection on the trail, with the added benefit that a hi-lift will also have clearance from the body. They are functional jacking points and I've personally tested them, even though I despise those jacks. Other people like them and carry them, so why not cut the holes so people can actually use them if they want?It ain't why I bought 'em, but @StinkBug are they a gimmick?
What did you use to mount them on the roll bar. What thread size is that ? Do you have a source for parts. Just picked-up a new unused hl485 for $70. Using it also with a lift mate to lift a Tesla to put jacks under it
I use it if I need it and have been since the 80's. It is like any other multi tool. It does not do any one thing as great as a purpose-built tool. It replaces many. I've used them as side come along when 2 winches are already strapped to a vehicle. I've used them to get out of mud but jacking up a truck and "pushing it off the jack to get out of ruts. I have used them to lift vehicles to work on (I suggest securing with a winch and rocks as this is very dangerous). And I once used the body of two jacks as makeshift control arms to get my lifted 82 bronco out of the woods after snapping a control arm. If you were trying to remove a tire you need to chain the suspension, so it lifts easier, especially on longer suspension travel rigs. Safe they ain't, useful, I have proven they are.
As for finish and upkeep, if you use it, it will get corrosion on it. I squirt the pins and mechanism before every adventure off highway. I pressure wash it with the undercarriage upon return. As stated above poor pin engagement is an accident waiting.
You can use the front recovery point on a stock bronco if you have this device called,
Those are cheap jeep mounts off ebay for a hood.
