Anyone use these yet on their C8 instead of jack stands? Seem to be the safest/easiest way to go especially since the entire underneath of the vehicle is covered.

I've been looking at a few different options and those are one of them.

Was also looking at RhinoGear's Rhino Ramps, those are only 8" but you can just roll onto them. At least if you are just trying to get the rear lifted. They will take up a bit of space though so I do see advantages / disadvantages to both. I have yet to decide.

Really would prefer a full lift or even a quickjack (5000 ext) but how often would I really use them is pretty minimal and I can't justify the cost... yet.

 

I have these and use these cribs all the time with my C7. I just jack one side of the vehicle up and put half of one crib under each wheel, then go to other side and do same, then go back to first side and put the other half in and then go to other side in put the other half in. My cribs are the ones that come in 2 pieces. The advantage of using these cribs is you only lift the car up 5 inch at a time. If you tried to insert both cribs under the wheel at the same time then when you go to the other side of the vehicle to lift it the vehicle is at such a steep angle that it is now difficult to get the jack under the car. Another advantage to using cribs is that you can precisely locate the crib under the tire. With a drive up ramp it is pot luck and you additionally run the risk of overshooting the ramp. There is no reason this could not be done on a C8 as well. Cribs are the safest means to lift a vehicle, most economical, and conserves storage space. I have been very pleased having these in my garage.

 

I have a pair of them, but I bought 8" high ones. Super light and easy to move around and store. I use them WITH jack stands........ when removing wheels, I'll put the jack stands by the wheel that is coming off, and put the cribs under the other tires that are not being removed. Then reverse the process for the other two wheels.

 

I know you want space to work, but i never raised my car 10 inches off the ground with a jack. Just seems a bit high.

 

It's not enough if you do exhaust work or change differential/gear oil in a C7.

 

I found a better solution for my needs just to raise maybe 7 inches or so. I found the (race ramps 56) inch which has a slight wedge so you actually drive up the ramp instead of having to jack your car up. I see on EBay for $238 Free Shipping.

 

I have a MaxJax and use it all the time

Is it a pain to "install" and "uninstall" it each time you use it and are done?

 

For jack stands I just use the aluminum ones from harbor freight. I remove the post that positions vertically so they are low enough to get under the car when it is jacked up. Works well.

 

Not very safe but if you enjoy living life dangerously go right ahead.

 

Good point MMD. I wasn't thinking about the steep angle with the single piece. I may end up going with the 2 piece as you stated. Thanks

 

I already have a low lift jack that I use on the C5 so I would just be getting the cribs. MMD made a good point about getting the two piece instead of the one piece though.

 

Ya know, I never really checked how high I lifted my C5, never needed to, as you know the underneath is not enclosed like the C8 so the Jack Stands were easy to place but, I'm going to check after you pointed this out .

 

Another point is that sometimes you may only want to jack up the 5 inches instead of 10. For instance if you are repairing a tire or removing a wheel to clean, or maybe you're replacing the brake pads you wouldn't need to bring it up that high. In this case use just one half of the crib. It will save a little time jacking up the vehicle in this case. Additionally you could use the cribs as a flat stopper so if you park your vehicle in the garage all winter you may put the car up on the crib (just 1/2 would be needed) to prevent flattening of the tire due to not being used. There is a lot of flexibility getting 2 piece cribs.

 

Hey Strake, In your opinion, Would the 8" be high enough for me to do an oil change or would the 10" be better

 

Pretty easy about 10 minutes to set up and take down. The part that does take some time (5 or 6 hours) is the first installation when you sink the mollies and epoxy them in. You need to take your time and get them instraight, it helps having someone to lend a hand. Other than that it's not an issue to use it. I've used it for everything from my lawn tractor, golf cart to a Suburban.

 

I have the 8" cribs and although I don't have my C8 yet, I did use them to swap out a C4 trans for a Tremec T5 on my 66 mustang. I kept my Mustang on those for a few weeks while I was restoring it. They held up perfectly.

 

That's my issue with high Stanchions. Have a set 12 inches high I used when building my street rod. Was on the garage floor for several months installing (and welding) the exhaust, gas lines, wiring etc etc. Worth the 2 step jacking method I had to use. Still have them BUT would not consider using for anything on the C8.

I made my own Stanchions from a $10 from a 12 foot 2X6 and some 3/4 inch plywood for my 2014 Z51. Have used on my 2017 Grand Sport to change oil etc. Used on my C8 to install low dust brake pads, side skirts and AC Condenser protectors. I show how to make them in my Jacking PDF: http://netwelding.com/Jacking_A_C7_C8.pdf.

Could make from a 2X8 or even 2X10 if you want higher lift. Funny, after having someone question the safety several years ago, for fun I calculated the safety factor. It's a minimum of 4.3, which is no doubt better than the plastic ones you can buy or plastic race ramps. Last month someone said it's only air under the 3/4 inch plywood top so I added to my strength calculations and note that the thinner plywood holding your refrigerator on 16 inch spaced floor joists is much less less than half as strong. In addition, the bridge you go over every day probably has a safety factor of 3 with lots of air underneath! All the data and this latest added safety info is in the back of the updated PDF. Your car your choice!

Pic C8 Side Skirts installed. NOTE: Lifts, quick jack and some combo lift jack stands would all be in the way when installing side skirts!


My ~6 1/2 inch high stanchions would fine for changing C7 oil.


Have 12 inch high commercial stanchions but needed a two step jacking process. Was fine when the street rod i built was in the air for several months when I installed the exhaust, gas lines, trans cooler etc etc. BUT would not bother with the C8.

 

While I haven't changed the oil on my C8 yet, I have had it up on the 8" cribs while installing my 5VM Carbon Fiber Ground effects side skirts and front splitter.

I would think it's high enough to slide under for oil and filter changes...... I mean you won't be able to sit up at all, unless you're a "little person", but you should still be able to do those type of tasks and get elbows moving and tools moving without issue.

If you are concerned, get the 10" ones, but I think you will see when you are jacking the car up to get those 10" cribs under the tires, that the rest of the car is pretty far up there. Kind of scary jacking that far up with a floor jack to me.......

I even changed the differential fluid on my Honda Pilot with NO jacking at all..... just slid underneath it with no lifting..... good thing I wasn't any bigger.
