I am looking to replace my upper strut bar and rear sway bar with a tsx bar.

I will replace both at the same time.

Are these the correct part numbers for the sway bar and bushings?
52300 TL2 A01
52306 TL2 A02
I also need recommendations for an upper strut bar.

I will also replace the end links with beefier once. I am in the midwest. Cars rust very bad underneath and replacing those end links later will be a pain.

2011 accord ex I4 sedan 30k miles.

 

A quick search says those are correct depending on if you want a 17mm or a different size.

However, I would recommend polyurethane bushings from someone like energy suspension if you're gonna swap it.

I deal with rust everyday here in upstate ny. Impact wrench and liquid wrench do the trick. Although sometimes it's no nonsense and I pull out my rotary tool. That's usually the case with sway bar links. On a good day the job will take me half an hour for both sides.

A good trick is to heat up the nuts with a torch first and then hit it with an impact. That usually melts the nylon lock inside the nuts. Then we use regular nuts with lock washers instead of the lock nuts incase we gotta get it back apart. If you dont have an impact wrench then you may wanna cut them off. Just be careful not to damage the strut tower (or lower control arm, wherever the link is connected).

I've looked into upper strut bars myself but have never bothered with one in my car. Many cars have them, many don't. In reality, it's added weight and clutter unless you're on a track often. Think about how much your strut towers actually flex. Cheap ones look pretty but bend, so youll spend a little bit more money. I've actually considered taking the oem one off the 5th gen v6 and putting it in my car just for kicks.

 

Where is a good place to find polyurethane bushings that will fit?
They have universal ones but about 20 different sizes of bushings.
These will hold up better over time?

 

You can check energy suspension for any parts that fit or even ebay. The bushings are tougher and harder. So you get less play and they last a lot longer.
