C8 Corvette Jacking Points and Jack Pucks: Where to Lift, Which Pucks Fit, and What Not to Do

I have owned four C8s: a Stingray, two Z06s and now a ZR1. Both Z06s sat lower than stock on Paragon Hyperco springs and collars, and a lowered car is where jacking a C8 stops being simple. The car only gives you four places to lift, the floor jack has to fit under them, and the same four spots are where you would normally want the jack stands. Here is where the points are, what GM actually says, which pucks fit, and the mistakes that put C8s on the shop floor.

Where the four C8 jacking points are

The C8 has four factory lift points, and all four are slots in the steel frame rails under the car. There are two per side.

• Front pair: just behind each front wheel, under what GM Authority’s write-up of the GM procedure calls the “frame rail shipping slot reinforcement.”
• Rear pair: just ahead of each rear wheel. The Autopian’s reading of the owner’s manual puts them in front of the rear arches, behind the rear edge of the side intakes.
• What they look like: oval slots in the frame rail. A puck drops in and turns a quarter turn to lock.
• What they are not: the other cutouts in the frame. CorvetteBlogger notes the frame also has holes for tying the car down on transport trucks, and an untrained tech can mistake them for lift points.

The rear points sit farther back than you might expect. The C8 carries roughly 40 percent of its weight on the front axle and 60 percent on the rear, so the rear lift points are positioned to keep the car balanced on a lift. Lift too far forward at the back and the car wants to tip rearward.

What GM says: lift pad adapters, not bare jack pads

GM’s own guidance came out in a TechLink bulletin for dealer technicians dated June 29, 2020, titled “Properly Lifting the C8 Corvette.” The short version:

• The tool: GM says Corvettes have required the J-43625 Lift Pad Adapters since the C5. Those adapters are what owners call jack pucks.
• The procedure: install an adapter in each front and rear frame rail slot, rotate it 90 degrees, then center the hoist pad under the adapter.
• Floor jacks too: GM says the same adapters go in the frame rail slots when you use a service jack.
• The warning: using the adapters wrong can let the car slip or fall off the lift or jack.
• Big jobs: if major components come out while the car is on a hoist, GM says to support the opposite end with jack stands and strap the car to the hoist.

The GM jacking procedure summarized by GM Authority adds two details. The service jack pad should be 2.5 inches in diameter or smaller. And the front jack pads must not contact the floor pan, rocker panels or fenders.

Jack pucks that fit the C8, with current prices

There are two styles. Twist-in pucks drop into the slot and turn 90 degrees, and you pull them when you are done. Bolt-in or lock-in pucks stay on the car, so any shop can see exactly where to lift. Prices below were checked on the vendor pages on November 5, 2026.

The ACS price is a sale price, with $129.00 listed as regular. The Paragon set is also on sale, down from $169.99. The BendPak set is marked down from $40.00.

The cheapest set in the table costs $34.00, and every set listed costs less than one scraped rocker panel. Leave-in pucks make the most sense on a car that goes to a shop, because the tech does not have to guess. CorvetteBlogger tells the story of an owner who runs red pucks and simply tells the service desk to lift it from the red parts. Twist-in rubber pucks make sense if you only lift at home and want nothing hanging under the car.

Stingray vs wide body: are the jacking points different?

Not that I can find. The narrow-body Stingray is 76.1 inches wide and the wide-body cars (Grand Sport, Z06, E-Ray, ZR1) are 79.7 inches, but the extra width is in the bodywork. The puck makers sell one C8 set across the lineup: Paragon lists the same set for everything from the Stingray to the ZR1X and Grand Sport X, and ACS lists Stingray, Z06, E-Ray, ZR1 and the 2027 Grand Sport.

What does change between cars is what hangs below the body. Side skirts, front splitters and aero pieces can sit close to where a floor jack rolls in. BendPak’s puck instructions specifically warn to check floor jack clearance if side skirts or splitters are installed.

How to jack up a C8 safely, step by step

This is the floor jack routine, built from GM’s procedure and the puck makers’ instructions.

1. Park it right. Level, hard floor. Transmission in Park, parking brake on, engine off, wheels blocked on the end staying down.
2. Set the front lift first. If the car has the front lift system, put it where you want it before the car leaves the ground, and do not cycle it with the car on a jack or stands.
3. Measure before you roll the jack in. Check the gap from the floor to the bottom of the puck against your jack’s lowest saddle height. On a lowered car, measure, do not eyeball.
4. Install the pucks. Twist-in pucks go into the oval frame slot and turn 90 degrees. Tug each one to confirm it is locked.
5. Center the jack under the puck. GM’s procedure calls for a jack pad 2.5 inches across or smaller. Raise until the saddle just touches, then check again that nothing else is touching: no rocker, no floor pan, no skirt.
6. Lift slowly and watch the car. Stop and look if the body flexes, the puck tilts or the car shifts on its tires.
7. Support it before you go under it. A jack is for lifting, not holding. Get stands or wheel cribs under the car before any part of you goes underneath.
8. Lower it the same way. Slowly, eyes on the puck, then remove twist-in pucks so they do not fall out on the road.

The jack stand problem on a C8

Here is the catch nobody mentions until you are on the floor with a jack in your hand. The puck is the jacking point, and it is also the only spot GM gives you to support the car. You cannot put a jack and a stand on the same puck at the same time.

Owners have worked around it a few ways:

• Jack one point, stand the other end. Owners on CanadianCorvetteForums report that lifting at a rear point also brings the front wheel on that side off the ground, which lets them slide a stand under the front puck, then move the jack forward and swap.
• Stands with a recessed pad. Jack-point style stands with a cupped top that holds a puck are the clean answer, if the stand and the jack both fit under the car together.
• Wheel cribs or ramps. For jobs that do not need the wheels off, drive-on cribs keep the jack out of it completely.
• A lift with the right spread. Owners on the same forum say some QuickJack models do not reach the C8’s wider lift-point spacing, so check the spec before you buy.

Two-post lifts: why C8s keep falling off them

C8s have come off dealer lifts more than once. In September 2023, a brand-new 2023 Z06 convertible fell off a dealer’s two-post lift on camera. CorvetteBlogger called it at least the third C8 known to have fallen off a dealer lift, and both the video poster and forum members blamed a lift arm that was not on the correct points. In March 2026, Torque News reported a 2024 Z06 with about 3,000 miles that fell while being put on a dealer lift during an oil leak recheck.

The pattern is the same each time: the arms go where they would on a front-engine car, the rear arms end up too far forward, and the 60 percent rear weight bias does the rest. If your car is going on a two-post lift:

• Pucks in all four slots, with an arm pad centered under each one.
• Nothing under the rockers, floor or skirts. The composite body is not a lift point.
• Rock test. Lift just off the ground and check that it is stable before going higher, then lower onto the lift’s locks.
• Ramps if needed. GM’s TechLink notes that ground effects may need gradual ramps so the lift arms can get under the car.
• Strap it for heavy work. If a transmission or other major part is coming out, GM calls for stands at the opposite end and straps to the hoist.
