Hi guys,
I recently bought a half-finished locost rolling chassis. I think I will have to replace the rear trailing arms because the current ones are a bit too short and the rear shocks are almost perpenticular (sp) to the ground.
That's actually a goal of the original design and probably just fine.

I am thinking if it is possible to use aftermarket trailing arm parts for 4x4s. Use bushing rod ends and aluminum hex rods. and then the arm would be length adjustable. Good idea or not? I have never seen people doing that on a locost.
There are lighter parts available from a number of suppliers, like the ones below. They're not that expensive.

Also, can you use sphere rod ends instead of bushing? I feel like the sphere rod ends would be pretty neat but it allows lateral movement for the solid axle, which is not good... Any opinion or suggestion?
Yes, see above photo. There are advantages to using both with the bushings at front and the rode ends at rear. As Marcus (horizenjob) said, you need a lateral locator. There are several options, but the Panhard rod is the simpliest and most versitile.
As Kristian (turbo_bird) indicated, you can fab your own if you have the skills and motivation.
Congratulations on getting the chassis and welcome to the zoo.
Cheers,
