Poly LCA bushings???

Good find!

 

Just moved back to Lloyd hahaha

Got tired of photo enforcement

 

haha tell me about it.

 

It looks like SPF3279K is the front LCA front bush and SPF3278K is the front LCA rear bush.

Great find @Bulhas !

 

They are here!

I forget how big the lcas are in these trucks!

Lifetime warranty even with offroad use!

 

They look stout! I have my old set of LCA's, I'll be putting these in along with some new LBJ's

 

Mine also arrived. They look like good quality bushings.

 

What material? I are they poly? They look like they might be rubber

 

I'll open it up tonight, I didn't take it out of the package. They are purple for sure, but fairly "slippery" feeling. A huge upgrafe over stock worn out ones and honestly I'm not fond of just changing to aftermarket arms

 

They are polyurethane.

 

I have a stupid question.

If I understand correctly, aftermarket LCAs have a grease zerk to service the bushings. Stock LCA don’t. How do you grease them?

 

You grease them liberally once and that’s it.

 

I guess you can compare them to the poly steering rack bushings, no zerk. Course the lca bushings see a lot more movement. Energy suspension has a real good and thick grease they sell that should last a long time. It’s the same grease that coachbuilder supplies with his shackles.

 

It's not a stupid question, stop humble bragging. They're gonna end up squeaking. You'll just have to take em apart, grease em, and put them back together. Still better than rubber bushings

 

So did anyone install these yet?
Do they fit/work?
How about drilling and tapping the LCA while it's off the truck and threading in a grease zerk?

 

If you use a good graphite spray that should keep them from squeaking indefinently. Always used it on the muscle cars we did with poly bushings until they came out with the polygraphite sets.

 

Finally pressed them out of one of my LCAs, it was like playing with dynamite lol! Sent an email to Energy Suspension to see what measurements they would need, really would like to use their graphite infused black poly bushings to help with the no grease zerk issue.

 

That would be easy to do. But they wouldn't really get greased well unless the bushings had grease channels cut in them

 

Here’s their response

 

Just installed my bushings.

 

very nice!

 

Front and rear are different part# and size correct?

 

Yes they are.

spf3278k Rear
spf3279k Front

 

ty sir

 

Dope

 

Nice! How hard was it to press the old ones out and new ones in? Did you apply grease while you were pressing them in?

 

Looks like they have a metal outer sleeve so you would want to put anti seize

Also, "Finally pressed them out of one of my LCAs, it was like playing with dynamite lol!"

 

ah right, I should track the convo better.

 

I used a bottle jack to press them out, there was no inching it out, it just all of a sudden goes flying across the garage so watch what you’re aiming at if you do it.

 

This. Mine didn't go flying out, but they possibly can. Easiest way was to use the bottle jack method.

I actually have a set of used LCAs I bought since I got a good deal on them with supplied cam adjusting bolts/nuts. They were in good condition, and the bushings came out with the sleeves in tact.

My original LCAs the sleeves stayed stuck to the LCA and the rubber bushing came out on its own, so I only pressed one out and decided to use the other LCAs.

I applied bushing grease to the new ones I pressed in using a 12 ton hydraulic press.
