Why No Rubber Bushing LCAs?
#1
![Default](https://ls1tech.com/forums/images/icons/icon1.gif)
With all the talk about the various flavors of LCA ends, (rod-rod, rod-poly, poly-poly), and all the issues (binding and/or noise), does anyone make a beefed up version of the LCAs with rubber bushings? I would think high durometer rubber bushings with fluting on the outer edges would be the thing for all but tracked cars. Be even nicer if someone (hint UMI) could just supply this type of bushing for replacement use in all those poly-poly arms that are binding and squeeking..

I just saw that Global West offers just that, rubber-rod. I'm probably going to get some to cut down on the noise with my rod-rod arms. And no I don't work for them, I just looked through their stuff yesterday and found some cool stuff.

You might want to take a look at the ones from J&M (hotpart.com). I have been running the street versions for several years and they work great. The bushing is a unique non binding poly/poly patent pending 3 piece bushing design.
Good Luck!

I actually had the complete "homemade" arm in the first link since I had the parts easily sourced at the time. If you already have a control arm with 3/4"-16 threaded bungs on each end, then either one of these threaded bushing cases should suffice (provided the overall length of the arm doesn't exceed 16").
What I can tell you is that even though the durometer of the rubber bushing is quite high, an XM_-12 rod end allows up to 14* misalignment so if those rod ends are used, then there should be minimal bind over the whole control arm altogether. Also, this rubber bushing was actually noticeably more quiet than the rod/poly (QA-1 rods) that I've tried, plus not having as much to grease for the overall vehicle was a plus. I figure they're worth the try than buying the GW arms, which aren't adjustible and are quite heavy.

Very good, I'll try this for sure. Thanks for the link Foxxtron, I'm registered there but haven't seen that before. You just saved me enough to go ahead and get some sub-frame connectors also.
The original link in that post no longer works, here's the current one I just dug up: http://www.lefthanderchassis.com/42.html

Thanks for the updated link to lefthanderchassis catalogue.
just an FYI, they can be sourced from other outlets as well...they're actually this bushing: http://www.howeracing.com/Suspension...erBushings.htm
Now maybe Ryan from UMI could answer this as well since I don't have easy access to the items. Even though I've seen Moog rubber bushings pressed into aftermarket tubular control arms, I wonder if the new threaded bushing from UMI is capable of the same thing? (some have designed their own tubular arms with "stepped" inner sleeve fitment, but I wonder if that's really necessary for an absolute secure fit).

We have always offered a rubber bushing in place of the poly bushing, it's just not listed on the site. The pricing is the same.
For what it's worth I have had both poly and rubber lower control arms on my daily driver and the rubber bushing had no effect on the et's at the track(low 12's)

Seems like the vendors should just have an "assemble your own LCA" type of thing on their website because everyone wants something different. And this seems to pretty much be the way you can do it.
