Universal Silicone CV Constant Flexible Velocity Joint Constant-velocity Dust Cover CV Boot Anti-aging Wear Resistance (6PCS)

real rubber. not plastic

Definitely Would buy again they were very easy to put on

100% recomendado facil y rapida instalacion sin desmontar tripoide ó junta homocinética del eje. el material de silicone ayuda a que estire sin romperse.

I don't know about newer Subarus, but the older ones (like I have) position the front right inner CV boot directly over the catalytic convertor. The catalyst cooks the CV boot, and standard neoprene rubber CV boots fail every 6-7 years or so. Then the grease gets flung all over the hot catalyst and smokes/smells bad. At least its easy to notice there's a problem so you can re-boot the CV joint before you ruin it...I wasn't able to find a silicone CV boot specifically designed for the Subie joint, but gave this a try. It fit just fine. I had to cut one "step" off the big end, but otherwise fit was great. The grooves for the clamps are a bit narrow, but were just wide enough to get the clamp in there. Also, because this silicone material is squishy an NOT fabric-reinforced, you've got to be careful how tight you pinch your CV clamps. If you do it too hard, you risk squishing out or even cutting into the boot. Snug it up, and add just a *bit* more pinch to your clamp.I'm concerned this boot is made of non-reinforced silicone material. It is super duper flexible and soft, but gives me the impression it will be really easy to tear or puncture while in service.I realize that adding fabric-reinforcement (like silicone turbo piping connectors) would stiffen the boot up. Perhaps that would make it unsuitable for a CV joint that is required to articulate through angles - but I kinda think that's what the ribs are for...to provide the required degree of freedom to make a bend.If this was fabric reinforced, I'd give it 5 stars. But its not. We'll see how long it lasts. I know it's going to withstand the heat of living near the catalyst, but I'm unsure if this material is durable enough to be a CV boot.Will update my review. Sooner if it fails, later if it's going strong!

Easy to cut if needed, but durable for maker projects for robots or pan tilt units as a dust cover while still allowing flexibility.

The media could not be loaded. too thin and too soft. It breaks during installation. It stretches well, but at the same time small holes appear through which lubricant will subsequently escape

$25 price is great for 4 boots but VERY thin rubber compared to other brands. I am returning for a refundbecause the amount time / work required to replace CV boots aren't worth installing lessor products to save $10. My time is more valuable . . .Thanks and hope this helps others make informed decisions
