Called around for quotes to get them replaced and everyone was quoting over $2k just for bellows. Figured I’d give it a try. The rubber is good quality and feels soft. Time will tell but this is an easy job if you’re mechanically inclined. Make sure you replace the plastic water pickup fitting while you’re at it. Found mine to be cracked on disassembly and had to wait for a new one. Should be a easy 3-4 hour job if your not doing the bearing and only doing bellows

Durable and well fitting

Durable and well fitting. I drive a Honda Accord 2014 and when the under engine covers started falling off I used these to replace the ones that came off. They work well and the prying tool made replacing the retainers easier.
