Review: 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. ## Features - Includes Clamp and Grease - For cars and trucks with large shafts - International products are subject to individual conditions and are sold from overseas and may differ from local products, such as fit, age ratings, product language, labels, and instructions - Attaches without removing axles ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00C2M795I | | Brand | FLEXX BOOT | | Color | 工場 | | Customer Reviews | 4.2 4.2 out of 5 stars (587) | | Date First Available | March 18, 2018 | | Is Discontinued By Manufacturer | No | | Item Weight | 358 g | | Item model number | FB3001 | | Manufacturer | Astoria 2000 | | Model | FB3001 | | Package Dimensions | 14.1 x 12.19 x 10.49 cm; 358 g | ## Images ![FB3001 Large Shaft Universal CV Boot - Image 1](https://m.media-amazon.com/images/I/71tj8Bt8rNL.jpg) ![FB3001 Large Shaft Universal CV Boot - Image 2](https://m.media-amazon.com/images/I/61fvdeWAahL.jpg) ![FB3001 Large Shaft Universal CV Boot - Image 3](https://m.media-amazon.com/images/I/71+E58o-g0L.jpg) ## 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.

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.
