Aftermarket trailing arm and rear sway bar

[04ls1gto]

Looking at upgrading my trailing arms and adding rear sway bar on my LS powered C10 suburban. Looking at the ECE trailing arms, whats everyone's experience? Also does a rear sway bar worth the $$?

Why do you need to upgrade the T/A's? Is there something wrong w/them?

Factory T/A's work just fine as is. If you want to upgrade, change the front bushing to something that reduces flex & has less bind than the factory rubber bushing. Some small lengths of stitch welds to ensure they can't come apart doesn't hurt or partial plating like the 3/4 ton trucks got (they used the same arms, they were just partially plated from the factory).

Switching to solid, tubular (square or round) T/A construction w/a poly bushing up front will stiffen things up. It will also cause binding faster than the OE set-up would since there's no ability to flex like the suspension design was intended to do.

My factory ones have quite a bit of rust in them and are splitting apart. One of axle bolt tubes on the driver's side is rotted through. Not sure of I can salvage them otherwise welding some plates top and bottom would help.

Then new aftermarket seems a solid choice if you can't find used replacements somewhere. If switching to a solid tubular type of construction, make sure to use a front bushing that allows movement/articulation (some type of spherical joint).
