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.

Worked well for 2013 Tahoe, used the giant cone. Lube up the cone , when the going gets tough- as it will mid cone- use a clean shop rug wrapped losely around the cone and use that to push on the boot. I found it easier to push with the cone standing on the ground and stop when the boot got to the flat part at the wide end of the cone, then move the entire thing to the CV axle and do the final push there.

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.

Disclaimer : long term testing has not been done but installation and fit and finish were great (only a few kms on for now). Installed this on a 2013 Dodge ram 1500 4x4. Was a fraction of the price of anyone one else. Came with grease and nice super tight fitting adjustable boot clamps. Beware you may have to stretch the boot rather far around sealing circumference of cv joint for some applications, I believe this to be normal being a universal part. Will purchase again for sure as long as the long term works out on this daily driver.
