Dug up an old unused box of Elite Engineering jacking pucks I bought for my C6. Does the C7 use the same size?

 

My '05 base jacking pucks don't fit, but my '09 Z06 jacking pucks fit. The aluminum rail on the C7 is thicker than the steel rail of the C6.

Both puck sets are Billet aluminum.

 

Thanks, I guess I'll have some pucks to sell.

 

I'm using the aluminum pucks from my C6 on the C7 and they work but I'm considering buying a taller set so that the jack will more easily clear the side rocker panels.

 

Might want to take 10 seconds and try them out????? We don't know what brand pucks you have. I have homemade out of hockey pucks........ used them on a C5, C6 and now 2 C7s. The holes on the C7 are narrower but I was able to shave the rubber inserts on 17 y/o pucks down to fit.

You do realize that for emergency use any hockey puck will work? No they will not "screw" in and hang but they are perfect to give you the clearance and protection when you need to jack the car.

 

First, GM says for C7 to use 2 1/2 inch max diameter pucks. I found the rocker panels are closer in my 2014 C7 than my C6 and those 3 inch aluminum pads did not work for that reason. As suggested above try them, they may fit and NOT hit the plastic panels.

A 3 inch Hockey Puck works for most folks as the eye hook can be pushed to one side of the frame slot.

I would NOT use any simple pad, wood or Hockey Puck without something that holds it to the frame IF you are using a hydraulic jack! The jack MUST move into the car as you lift so the jack saddle stays under the pad. Pads anchored to the frame "help" pull (but do not guarantee) it along-MOST times! I know because it didn't once when jacking on a rough concrete driveway!

See pics below:



How Much Jack Must Move in to Stay on Jack Pad Depends on Jack Size
Note: Measurments assume all lift height is the max for the small jack.

 

I've have the hockey pucks that have rubber inserts in a storage pouch in my trunk. They generally stay there. When I service the car in my garage which I do regularly I just use a rubber hockey puck which compresses with the jack. In 17 years I have never had a problem. But it depends on other factors. I'd never jack up a car on a rough driveway and expect the jack to properly travel. I have metal plates I set my jack on so it is free not to bind. This allows the wheels to freely travel. The wheels are there for that purpose. In fact when ever I work on any of my other cars I always use a standard hockey puck.

I keep my jack pads in the compartment in the rear in case I have to go to a dealer ("cringe") or a tire store. I put one of my now 4 hydraulic jacks perpendicular to the Vette AND carefully swivel the rear casters so they are ready to move in. In the 30 years I have had Vettes (and before) never had a problem! But only takes once!

The issue occurred with my small, short arm jack so went and bought a long reach jack from Harbor Freight that needs to move in much less! However it weighs 95 pounds and when I went to use it on my very smooth tiled garage floor it was not moving in! The problem is to have the jack spec showing it can reach very low they made the jack saddle very shallow! Solved that by welding a 1/2 inch steel strip to the edge of the jack saddle! Now, with a proper jack pad that inserts into the frame slot it pulls in fine! Would pull in on my concrete driveway as well! The key is to watch the saddle jack pad relationship as you lift!




Even jacking on my smooth titled garage floor, the newly acquired, long reach, 95 pound jack was NOT moving in as it lifted! Would be worse on concrete!



Welded a 1/2 inch steel strip to the jack saddle using spot welds than filling in-between, (the reason for the rough appearance but functional!)

This is where the slipping issue occurred on my prior 2014 C7. The surface is NOT that rough and the jack did move in but NOT enough. My bad for not watching the jack saddle jack pad relationship after each pump. No one was hurt but it did slip! Just providing the info to make all aware of the issue.

 

Play it again sports stores usually carry used hockey pucks for a buck or two!

 

Hockey Pucks for under 10.00

 

I use the same pucks on my C5,6 & 7

 

I agree, try them. It depends on the manufacturer of the puck. When I purchased the C7 I bought a new set of pucks and lost one when I forgot to take it out before heading on track. Luckily I had one of my old C5 pucks made by somebody that I tried. It plugged right in to the C7 slot and the only issue was it wasn't quite as thick as the C7 puck but it works fine with my lift and I don't use it when jacking the car at the track since I only use one puck while doing that.

Just a standard hockey puck or a small scrap piece of 2x4 will also work if needed. If you don't have anything the area around the front slots is wide open so if you can place your jack in there without its frame hitting the side skirt as it comes up then you don't even need a puck. All they are is spacers. They were absolutely necessary in the rear slots of a C5 because there was no room around them to place a jack or a lift pad without hitting the rocker panel. C6 opened up the space around the rear slots and reduced the need for the rear pucks and the C7 has pretty good area around the rear slots so you can get by without pucks if you are careful.

The C5 Service Manual told mechanics to use the pucks in the rear slots and didn't mention the front slots at all. I haven't checked my C6 or C7 manuals to see what they say but they may be the same way. The pucks aren't meant to protect the frame they are meant to keep the lifting device from lifting the car by using the plastic the rocker panel instead of the frame.

My 05 pucks fit no problems on my 14 not sure the brand but can't imagine them being much different.

 

Here’s my rig. I went to a metal shop and picked up some sheets of 1/8 metal. I never jack any vehicle w/o these under the jack. And I pay attention that the jack is rolling lifting and dropping.

 

That's how I found out one set worked, and one did not.

 

When we bought our C5, I purchased real hockey pucks and stainless eyebolts from Home Depot. Drilled the holes through the pucks slightly smaller than the threaded shafts on the eyebolts and the bolts cut their own threads as I screwed them in. The bolts can be adjusted by screwing in or out so they fit just right into the frame slots, so they worked just fine on our 2001, 2006, 2009, and now 2017.

17 years later, still using the same pucks.
