Description
Cusco's rear trailing arm controls unwanted force under acceleration and braking. Cusco's adjustable pillowball trailing arms prevents unwanted wheel hop and vibration under acceleration while providing smooth braking at the same time.

This Trailing Arm is adjustable allowing you to fine tune your rear alignment for ultimate performance.

These are not for rear toe although they will have a slight impact on toe as anyone who has played with the rear suspension on the car will know. They are not the same as the WL toe arm. Having this arm be adjustable is quite pointless unless your slammed and paying that kind of money for it is a waste but to each their own.

It does nothing to the pinion angle we dont have a solid rear axle the differential is fixed thus its angle relative to the drive shaft is fixed..

My bad... I thought these were the same piece as the WL toe arm. Not sure how I missed that.

I see your point. I missed two key words when researching for my previous post - beam axle.

I'm currently researching the value of upgrading the trailing arms.

Would I spend $500+ on aftermarket trailing arms? No

Would I upgrade to better bushings to reduce "goosh" or squish in the bushings? Yes

Is there a need to install shorter trailing arms due to a lowered suspension? And, if so, how much lower needs the upgade? It appears so
This is where an adjustable unit would apply, especially if you can get a quality adjustable unit for less than a quality fixed length unit

Is there a need to install stronger trailing arms due to flex in the OEM units under acceleration / braking? It appears so

On the GR/GV chassis the benefit to adjustable arms, is the fact that now you will aint at least some rear camber adjust ability.
If combined with the Lateral links and Whiteline toe arms your able to get a very large amount of rear suspension adjustment to fine tune your set up!

Bumping this as I am having a current issue with my OEM trailing arm with RCE yellows.

Are these needed or helpful when you're lowered (0.75"?) on RCE yellows to reduce the length of the arm.

Right now my bushings are making noise from the arm and when I took it off to install a brand new OEM one, I noticed the arm was longer than needed and I had to push/force it in it's place.

I had no issues at all with the RCE yellow and only have the cusco LCA installed.

This really is kind of a strange part that I don't typically recommend. We sell them - but really only once in a blue moon. If you are slamming the car on the ground at the expense of suspension function and travel being able to adjust the length of the trailing arm can be somewhat useful. If you are running the car at typical ride heights with just a modest drop to retain proper suspension function then being able to adjust the trailing arm is pretty useless in my opinion.

You end up spending $404 depending on who you buy them from and the only real benefit you get are the spherical bearings in the front position. The rear position trailing arm bushing is actually in the hub, so it doesn't even replace this one. You're much better off just buying two aftermarket urethane bushing kits (Super Pro makes a nice set) and replacing both the bushings in the factory trailing arms and in the hub.

Thanks,
Geoff
