Rear upper/lower links (trailing arms)

[SoCal818]

Forgive my ignorance if this is an elementary question. I’ve been researching when (or why) to upgrade the stock upper/lower links (aka trailing arms) and haven’t really found a satisfactory answer. Has anyone done this and have any feedback to share?

Here are two options I’m considering:

1. 2001-2007 Toyota Sequoia Adjustable Trailing Arms | Fits Stock to 6” Lift - https://apocindustries.com/products/1996-02-toyota-4-runner-adjustable-trailing-arms?srsltid=AfmBOooylzuVR2T1Q8tnidqo3bBxGNV9JCp_ih4JOi5k8O0K2iwnh8tM&variant=41658422067261

2. Rear Adjustable Control Arms (01-07 Sequoia)Full Kit: Upper and Lowers - https://optoffroad.com/products/rear-adjustable-control-arms-01-07-sequoia?srsltid=AfmBOor0v8j3hx2HGmGm5xNCG7ZsMV54ChMNh9IaC0Sa2YmCIWJXsqOq&variant=46030086734082

Thanks in advance.

I'd look at Dobinson and maybe whiteline as well for good quality, without the price tag of some....

Thanks. I’ll take a look. Have you upgraded the trailing arms? Experiences?

I've done rear arms for my 80's and 200's - about to do a setup for my current gen 3 Tundra to get a bit smoother and full travel for the 37's....

if you're lifting enough to want arms - you also should look at adjustable track /panhard bars.... and a KDSS bracket to level out that angel to reduce bumper steer and center the rear axle again....

Thanks. I’ve got the Panhard Correction Kit welded in and found that to be helpful with making the truck feel more stable at speed. Curious if upgrading the trailing arms will make a similar improvement.

I had Icon's Alum setup on my old 200 and it gave it a bit smoother ride and also with longer shocks more travel (12"+) so it didn't top-out harshly - and the Icon shocks were adjustable which helped tune it for the situation better....
