Review: Easy Install. Great flexibility! Highly Recommended. - 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.
Review: A great alternative to just replacing the shaft - 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!

## Questions & Answers

**Q: Will this fit Kubota rtv500?**
A: Adam,
We do not have a listing for the RTV500.
We have a listing for the 2003-2008 RTV900 that shows that the cv joint is under 19 mm so we would recommend the FB2000 for that application.
The FB2000 is used for joints between 14-19 mm.
The FB3000 is for joints between 19-24 mm.
The FB3001 is for joints over 24 mm.
Please confirm the joint size and check out  the boot schematics and installation videos on the Amazon listings.

Good luck and Stay Safe,

DB

**Q: Does this fit outer cv shaft right of 2007 chevy avalanche 5.3l ltz?**
A: The FB3001 should fit fine as the small opening is over 24mm

DB

**Q: do these fit 2006 mercedes  e55 amg?**
A: Erica,

Sorry but we do not have any information on the E55 AMG.
The FB3001 is a Universal, High Stretch, Highly Durable boot that usually fits joints that are 24 mm and larger.
If the joint is under 24 mm we recommend the FB3000 boot.
Please confirm the joint size and compare to the boot schematics and installation videos on the Amazon listings.

Stay Safe,

DB

**Q: Will this fit a 08 silverado?**
A: Our information shows that the Silverado joint is over 24 mm so the FB3001 should fit. 
Please confirm the joint size and compare to the boot schematics and installation videos on the Amazon listing. 
Stay safe.

### ⭐⭐⭐⭐ This said it fit Chevy 1500 & Cadillac Escalade - they do.. ignore the specs in pic
*by K***. on January 2, 2025*

Needed to fix axel in an Escalade, the Axel shaft is 29mm and the CV Joint end is 100mm the spec in the pic lists 85mm and axel size of 19-24 But the rubber is flexible and easily stretches... I give this 4 stars . i did not like the clamps and had lots of thicker ones so i used those ..
