This threads a year old. No updates? Rusty obviously didn't buy these and went spl everything.

The OP never did any up-dates, so I went with SPL.

I want them to replace the bushings in my adjustable control arms with poly/grease bushings.

Why don't you go with aluminum/bronze bushing for there with grease fittings.

Link? How do I know these will fit diameter and length?

You can have a local machine shop make them for you. All they would need is the arms, old bushings, and bolts to take measurements. I used to be able to get parts made reasonable. But now with the gas well drillers here. Prices have shot up, and you have to wait in line. The shops are making a killin' now.

Why can't that joint just be solid? Fill it in with a sold bar, drill the hole for the bolt size and install the bolt? No chance of movement lube the bolt every now and again.

I would imagine a solid metal cylindrical bushing + bolt would bind in some situations, even if lubed. If you gave it enough looseness to never bind, it would have more play in it than the delrin version.

I prefer this. Need to find out how he did these. He tried selling these for $600 but to me they look like ams or kinetix arms with upgraded bushings and maybe the hemi joint or whatever.

Sorry for the lack of updates everyone, but the delrin bushings are still working great. Have them on the LCA's as well. Of course for adjustability I would prefer full replacement arms machined from aluminum or fabricated from steel tubing, but that takes much longer to design and make, and is 10x the price.
If anyone is interested in the front upper bushings, I have a few sets to sell for cheap.

In the rear suspension I have mostly spherical bearings for the joints, as it's simply easier to purchase high quality parts that are already available.

Considering the low cost of installing delrin/aluminum upgrades, and sometimes restricted by rulebooks, it's a simple upgrade. On the downside, there can be occasional noises either from road conditions or a lot of suspension articulation.

I'm interested in these. You need to clear out your inbox, it says you can't receive any pm's

I'm interested as well. Think there's a PM from me in your inbox somewhere. Thanks

Also interested in lower control arm bushings. SPL is the only option we have for those I believe. How would Delrin work for the rear differential bushings?

If the OP cant or doesnt sell these anymore, My company would love to offer these. We have a cnc lathe sitting waiting to cut some delrin bushings.

I'd be interested in sending you my aftermarket front arms and having you do this since the aftermarket arms might not take his. Also PM me a price on porting my throttle bodies and manifold like Z1 does.

sorry it was to strong to resist for both options, which one of them Z1 is now performing...
