FB3001 Large Shaft Universal CV Boot

I recently used the Flexx Boot CV Boot to replace a torn CV boot on my front axle, and I couldn’t be happier with the results. This product is a real game-changer for anyone who wants to avoid the hassle of removing the entire axle. The installation was incredibly straightforward, especially with the included zip ties and grease packet. It fit securely and sealed tightly—no leaks or mess. The best part? It saved me hours of labor and the cost of a full axle replacement. The material feels durable and flexible, and it's held up perfectly through several weeks of driving in various weather conditions. No clicking, no grease loss—just smooth performance. Highly recommend the Flexx Boot to DIYers and mechanics alike. It's a smart, time-saving solution that really works.

Exactly what was needed. Much thicker and better quality than the boot that came off. Fit perfectly and it came with the clapt straps to keep it in place. A great value for the money!

The Axel was fine just needed a new boot so I saw this and tried it and it worked good and fairly easy to install

2009 Chevrolet Silverado 1500 A bit loose, particularly on the narrow axle shaft side. That made it a bit of a trick to get it tight enough with the clips. But all in all very happy to save $250 for a new axle when the boot had only just failed. I will see how long they last. They seem solid enough, maybe a bit more rubbery than I had expected.

Had to replace the boot on the driver side CV joint of a 2009 GMC Sierra 4x4. While it did work, was not a perfect fit, but to be expected with a "universal'. Material is quite stretchy and flexible- more so that the OEM or any others I have used in the past, so we'll see how long it lasts. The included clamps are cheap and weak. I used a more heavy duty stainless set I keep on hand for this exact reason. I would not trust the ones that came with. I'll update is there are any issues or additional feedback.

Boot is a perfect fit on our 2000 Chevy K3500 7.4l passenger side cv axle. Boot is pliable enough to slide over the axle joints without a spreader and comes with grease and new replacement clamps. Much better than replacing an axle because of cracked boots. Am going to order a spare set for the drivers side axle.

Didn’t work on my truck. Ended up just replacing whole part instead of just boot.

This boot worked perfectly to replace the original torn boot. The bands were also easy to install. I did not repair it on the vehicle. I removed the axle.
