Hey everyone, im wondering if any of you have any experience with silicone cv boots, preferably on a Subaru?

It seems the "real 4wd" guys seem to like silicone boots on their lifted ifs trucks, but havent seen anything about silicone boots on a Subaru.

Anyone try them? Worth trying out?
 
Are you looking at using the silicone split CV boot or universal one? My concern with the silicone ones is that, while they may be stretchy, they are just too thin. It would be nice, though, to use silicone as most Subarus' right hand CV boot is close to the exhaust.

I have an experience using the silicone rack end boot and they tore up a bit too quickly after a few kms on my brother's GC8. We reverted back to OEM and the rigidity/quality improvement is somewhat significant. The thickness of the CV and rack-end boots are rather similar. If I can find a silicone replacement that is a bit thicker or almost as thick as the OEM ones, I may reconsider using it. Cheers.
 
Not looking to use the split boots.

Ive just had my 2" lift on my Forester for 2 weeks and already noticed the boots rubbing themselves thin.

I just noticed some "real 4wd" guys loving their "high angle" silicone cv boots, and noticed some of them had some o-rings between the humps on the boots to help stop them from rubbing.

So im either looking for some universal silicone boots and adding the o-rings, or adding o-rings to new oem boots.
Or go down to a smaller lift :(
 
That one can benefit the lift, as well as the heated CV boot syndrome. It seems that these high angle ones are thicker than the common universal ones that I have seen.

The high-angle one has one of those o-rings that you are referring to. It seems that the difference is how widely-spread the crests are compared to OEM. This may work, actually.
 
Those are the ones i saw that sparked the silicone boots for me

Think im going to crawl under my Foz tge next day its not raining and take some rough measurements to see if those ORS high angle silicone boots might fit. Just sucks i need 8 instead of just 4

Keep us updated on this. For reference, the inner diameters of the mounting flanges are 1" for the small hole and 3.5"
large one. Cheers.
 
I have "Stretch" branded CV boots. Haven't worn any of them yet. My longer coilovers give them a bit of angle. But it's only been a few years. For the fronts you have to cut up the old boot so you have a ring that sits over the larger side and stretch the new boot over the onld boot so that it wills in the funny shaped grooves.
 
how many miles do you have on the stretch boots?
 
Red xs, do you have the stretch boots on inners, outers, front rear?

Which part number
 
Sorry was away for a bit. There were 3 sizes I used the standard size.
