Greaseable Shackle Bolts

Anyone using greaseable spring shackle bolts?
Bolt size?
Both ends of the spring?
Source?

Thanks!

Re: Greaseable Shackle Bolts

They only work if switch to poly bushings and they require drilling the bushing sleeves also.

The IronRock springs I'm looking at have poly bushings. That would leave only the shackle mount to be converted.

Hardly worthwhile unless you do both!

Makes sense. I'm not sure it's going to make a huge difference and with poly might be less of an issue, and they're greased at install. Seems like OEM rubber lasts quite some time and poly probably more.

Re: Greaseable Shackle Bolts

I don't think poly needs the grease so much for durability as it does for noise.

The deciding factor would be your tolerance level.

Good point. Looks like poly is standard now on my springs of choice.

Greaseable Shackle Bolts

The poly on my front arms is dreadful when dry.

I've thought about tapping spring eyes for grease zeros. I have crown springs and poly bushings. Still debating grease zerks

Most here know that that won't work.

Re: Greaseable Shackle Bolts

I'm not clear on how a greaseable bolt would prevent poly squeak. Grease would be between the bolt and bushing sleeve, not in the poly bushing itself, correct? I'm thinking a film of quality grease when the poly bushings are inserted should be sufficient.
My JKS poly front arms are greaseable. Have never noticed any squeak, but then the
C L U N K from my worn out drag link ends overpowers any other noises.. lol. Soon to be remedied.

Re: Greaseable Shackle Bolts

That's why the bushing sleeves have to be drilled also!

Rcp is correct. Sleeve needs a passage so grease travels to bushing

It would work but I'm not sure drilling a hole in wrapped spring steel is structuraly a good idea.

Re: Greaseable Shackle Bolts

Found greaseable bolts but M14 x 2.0 x 130mm instead of OEM 120mm (+0.4"). Will these work or will they bottom out you suppose?

Not a must have but I do like the idea of lubrication on the bolts/sleeves.
