Cobra and GT40 Spinner Removal Tool
BENEFITED & INSTRUCTIONS for three eared spinners.
This kit fits Carroll Shelby, Halibrand three eared style, spinners for Cobra, GT40, Mustang, Daytona coupe and many more that use that type of spinner.
Here are benefits and instructions on this 3 eared removal tool Kit. You will only need a breaker bar and a torque wrench.
The Cobra and GT40 tool come as an Aluminum CNC milled tool, smooth finished, wrapped in black leather to protect any metal to metal contact, a six point, CR-MO 46 mm impact socket, a wheel chock to keep the wheel from spinning on the floor, and a tool storage bag. The tool is engraved with UNDO right and left directional arrows.
The normal recommended way to remove a wheel is to use a lead hammer to loosen the spinner while the car is still on the floor. Jack the car up, remove the spinner and wheel, replace the wheel then figure tight the spinner, let the weight of the car back down and use a lead hammer to tighten. Jaguar guys say NO, you need to roll the car a short distance and re-tighten with a hammer for a well seated spinner to the wheel.
The benefits of the wheel chock is to simply jack the car up just so the tire just turns, place the chock on one side of the tire to loosen and move the chock to the other side of the tire to tighten, then let the jack down for a perfectly seated spinner to the wheel. It is that simple.
The tool has a 2 inch depth to handle those extra long hubs that protrude more than a normal threaded hub. The tool's height is taller and with the taller impact socket the tool can reach into the deepest wheels. Where a hammer will have a hard time getting a good swing to loosen those tight spinner.

How to change a wheel without using a hammer.
The only settings I have found was in a Lotus Elan manual and showed 200 to 220 ft/lbs. of torque. The threaded Hub measurement of the lotus was very close to the Cobra Hubs. My standard Cobra tool kit uses a 46mm, impact 6-point socket with a 1⁄2″ drive.
A shop owner who has always used a lead hammer to UNDO his spinners, said “three good whacks, does it”. We tested his 3 whacks method, and he hit between 3 and 4 pounds, each time of 210 ft/lbs. He did say that using our tool with a breaker bar’s leverage caused the wheel to spin on the floor. He suggested blocking the wheel.
The standard accepted tire removal method is to loosen the spinner with a hammer while the car is still on the floor, Jack the car up, remove the spinner and the wheel, replace the wheel and finger tight the spinner and let the jack down to keep the wheel from spinning and tighten with a hammer.
With a wheel chock you simply jack the car up just so the wheel can just turn, place the wheel chock on one side of the tire to loosen and move the chock to the other side of the tire to tighten, let the jack down for a perfectly seated spinner to the wheels. It’s that simple!
Facts about what size drive sockets to use.
My standard Cobra tool Kit (part # 900) uses a 46mm high-end impact socket that has a 1⁄2" drive socket. Most breaker bars using a 1⁄2" drive can handle up to 300 to 400 lbs. of torque without breaking and twisting off. That is enough to UNDO a standard stated spinners torque of about 200 to 220 plus ft/lbs.
For spinners that are over tightened or seized, I offered a 3⁄4″ drive socket to handle stubborn spinners to avoid ear damaged or severe removal methods.
A big compliant was trying to remove seized spinners.
My tool kit can reach into the deepest wheels and grips all 3 ears and applies equal force evenly to all 3 ears. When using a hammer, it would be difficult to get a good swing in those deep-set wheels, one ear at a time.

If you have recently used your standard hammer swing and have used anti- seize on them, make a mark on both the wheel and spinner, Loosen the spinner using your standard hammer swing and retighten with a torque wrench to the 200 to 220 torque settings to see how close the marks line up.
If your spinners are over tightened or seized, make a mark on the wheel and spinner. Use your hammer to know how much force it took to break them free. My tool with a 3⁄4″ drive socket could apply over 1,200 pounds of equal force to all 3 spinner ears. Remark the spinner and the wheel and use a torque wrench to see how close the markings line up using the torque settings. You can increase the torque settings if it is needed. I recommend using a quality External head breaker bar. The internal head type breaker bar has snapped off and failed when the force exceeds 350 lbs.
Many Cars that use the Halibrand type spinners use on Shelby cars.
Facts about what size drive sockets to use.
Most breaker bars using a ½” drive socket and can handle up to 300 to 375 lbs. of torque without breaking and twisting off.
My standard Cobra tool kit (part # 900) uses a ½” drive, 46mm high end impact socket that has a ½” drive socket.That is enough to UNDO a standard stated spinner’s torque of about 200 to 220 plus ft/lbs. or a little more.
For spinners that are over tightened or seized, I offered a 3⁄4″ drive socket to handle stubborn spinners to avoid ear damaged or severe removal methods.
A big compliant was trying to remove seized spinners.
Some have used up to 1,000 pounds of force to remove seized spinners. When using a hammer, it places all that high force onto only one ear at a time, weakening the spinner’s ears and breaking some off.
