Normal life is around 5 years +-.
If they do fail and you nicely contact. I'll more than likely take care of you no problem. If you are a dick about it. Then not so much.

I have a baggy of the crumbled Kartboy bushings. I replaced all the bushings on my truck about 20 years ago with Energy Suspension polyurethane replacements. This includes shocks, endlinks, swaybar, control arms, spring eye, etc. Not one of them crumbled into little pieces. Not one. All of them are fine and I still have the truck. So I don't buy the 5 year life excuse.

Gotta love people that don't understand when a product is poorly made.

So none of those are attached an exhaust that's at several hundred degrees then.

Sorry you can't read, but his x-member bushing also crumbled to little pieces. Especially when other manufacturers like Cobb and TIC (the non KB ones they sell) as well as OEM doesn't. Yeah, Kartboys bushings are poorly made/designed.

i have replaced a bunch of energy suspension poly parts, they have all crumbled. mainly where there is a lot of movement, say sway bar endlinks.

+1 for a vendor not afraid to speak the truth

Funny, Tom said his bushings are petroleum sensitive. Meaning if they come into contact with gas, oil, grease, etc, they break down. Which isn't a problem with other manufacturers.

My energy bushings are still fine after 20 years. Maybe they were properly installed.

Also, it helps no one (including the manufacturer) to cover up and/or stick up for a poorly made/designed product.

For what it's worth, I've had the Cobb hangers installed over 6-7 years, up to 110 degrees, down to -10 degrees, and about 50k miles including autocross and they're holding up just fine.

I didn't install them, previous owner did, so no idea if any lube was used installing them.
