silicone cv boots...Thoughts? Experiences?

Just as the title states, I'm looking for thoughts and experiences on silicone cv boots. Are they worth the extra roughly $20? And will they hold up longer to "fin" rubbing and offroad abuse?

Any other info you can provide would be great...

 

I'm not sure. I'd think silicone wouldn't last as long with fin rubbing, stretching from turning/flexing I have no clue about. But sub'd for other opinions.

 

I thought the same thing, but after some online research and talking to CVJAxles, apparently they are preferred on "custom" axles for rockcrawlers, etc. That makes me wonder orquestion if it would be a good option for the angles 3” lifts do to 2ndgen axles.

It's an option through them on the stock rebuilt half axles...

 

I have CVJs on my runner, been on since summer with the silicone boots. They have been holding up great so far, but still limited miles. They definitely have not slipped or leaked grease like the stock did after lifting though.

Check my build for pics.

 

I checked out your build, looks good. Great Pictures!

Do you know why they don't offer the outer boots?

I will probably give these a try, but I'd like more feedback...No such thing as to much feedback

 

Thanks!

I think it's because most of the strain and flex comes on the inner. That is where all the boots that I have seen leak from or bands come loose. CVJ was great to work with, they are local to me so that helped, but even over the phone they were very helpful. Highly recommended.

 

I've used them, and can't see any longevity issues different than a "normal" boot. They aren't any better, and seem to get holes poked in them easier, but don't split...maybe you could try running a leather boot over them like on porches?

 

What brand did you have, or do you think they all come from the same place regardless (china)? And by holes do you mean from shit on the trail like branches?

 

I think they were Empi? I got them at Kartek, and if anything were probably of German origin but who knows. Yeah, branches, rocks, whatever. I only had that problem on the outers though, so maybe they would make it as inners. I'm running the All-pro "long travel" outers and haven't had a problem with them at all. I have about 30,000 miles on them or so (longer than any other boot lasted me, I'm hard on stuff though).

 

This could answer why CVJ only offers "standard" outer boots.

I looked at Allpro's website and it appears even though theses are "long travel" boots they recommend them for all lifted applications. I wonder if anyone who's not long travel is running these for outers...

 

Yes, they will fit on any taco. They are a little longer, but they hold tight with the plumbers tape style clamp they use. I use those clamps on all four positions, it makes changing boots much less hassle.

 

Low Range sells these outer LT boots also. They actually fit over the OEM boot and the guy I talked to at Low Range wasn't really keen on them.

Edit: actually can someone verify this? http://www.lowrangeoffroad.com/yota...ner-long-travel-outer-c-v-boot-and-clamp.html
