Have 4 HF jacks! Have the 95 lb long reach and IMO it has some issues that you should consider. If I was only buying one I would get a somewhat shorter, 15 inch long arm jack. Those issues are covered in the PDF.
I also show a number of jack pads. I like aluminum jack pads and ones from Reverse Logic Are ideal when having to visit a tire store of dealer service where they can be bolted in temporarily. I keep those in the rear compartment.
This is a 1 pic summary:
Hydraulic jacks MUST pull themselves into the car as you lift to keep the jack saddle undervthe jack pad and not slip off. The 95, lb heavy long reach jack was not pulling in on my smooth tiled garage floor! Never would on my concrete driveway so increased the height of the very low jack saddle recess by welding on a 3/8 inch steel thick strip! Works fine now. Note: X is based on all other jacks lifting the same height as the MAX for my small jack where I did encounter a slipping problem.
Used hockey pucks at Play it again sports for 1 dollar used or $2 new
That's what I did and I drilled a hole in the middle of them and put screw in J-hook bolts in them and just put then in the frame hole and twist and they stay in place. Made all 4 for $35.
I went with ZL1 Addons jacking puck ( permanent pucks ). www.zl1addons.com Here is picture of pucks on 17 GS.. Corvette tech at dealer stated he like the quality of pucks when I did my oil change. There made of solid aluminum and I thought would hold up better than plastic permanent pucks I have seen.

I too got the ZL1 Addons. Semi-permanent and semi-expensive but quite nicely done and handy to leave in place.
Btw, they came in a box that looked nicer and was better made than the containers some of the $5K watches I buy. All done to the same high level, imho.
DON'T buy the plastic pucks! See below....When the puck collapsed as the C7 was being jacked up, it almost took out my rocker panel, fender and door.
Agree. I would not trust the weight of the car on anything plastic or rubber, even hockey pucks can distort a lot under load, which could allow it to slip of the jack cradle
I've had the HF 68050 jack for five years and it has been flawless, albeit quite heavy. Moving it around on a concrete garage floor hasn't been an issue, though. I bought a QuickJack BL-5000-SLX about a month ago and all my full-car jacking hereafter will likely be with it. I also have plastic stay-in pucks from Southern Car Parts which I originally bought for my C6 and have now been on two C7s. No problems with them either.
I've been looking around here for some time trying to find the best jacking pucks and jack combination to use for raising my '17 Grand Sport without risk of damaging the GM side skirts.
I've found that the Harbor Freight 2-ton (#68050) low profile/long reach jack works great along with the standard (not extended model) Reverse Logic jacking pucks (#C28-63). With pucks installed and #68050 lifting there's just over an inch clearance between the jack and the skirts.
I expect these Reverse Logic pucks will also work fine for dealership/repair shop jacking systems as well.
I sold dozens of both expensive leading brand and inexpensive jacks when I had my Auto Parts stores and never had an issue or warranty claim with either so don't expect any problems with the HF #68050. It seems to be quite a jack for the $119.95 that I paid on sale.
I looked hard at both 2 and 3-ton HF Jacks, however I really like the long reach of the 2-ton (68050) along with it being lower. I wanted to be sure not to risk cracking my skirts and feel the longer reach may come in handy for jacking underneath as opposed to the frame rail. I also like the versatility of both a foot pedal and handle for raising. The foot pedal comes in super handy if car is near a wall and the handle doesn't have space to travel up and down to jack.
It is heavier than the 3-ton at about 90lbs but I'm only going to be rolling it not picking it up very often.

Do you have the Stage 2 side skirts on your car? If so the I’m assuming that these ZL1 pucks protrude down far enough so that your jack clears the skirts, right?
I have the carbon fiber side skirts on my GS and my hockey pucks with eyebolts (bought on ebay when I had a C6) work fine with my $60 Harbor Freight jack.
Here is a tip I stumbled onto to protect your car if the jack leaks down and it also is easier than cribbing or using a jack stand. Use a short piece of 2x4 long enough to spand the width of the jack placed between the scissor. If the jack leaks down the 2x4 will not let it collapse. I wouldn't recommend using it to lift very high due to the severe angle but it works well for R&R wheels/tires. There is a puck on top of the othere piece of wood, just used it to fill the dish in the jack head.
