Might be a dumb question, but are the Rear LCA’s the same right to left? I don’t have my car in front of me to check and the microfiche lists it as ARM, RR. (LOWER) 52350-SR0-A10. It says Qty. required is 2 so I assume they’re the same right to left, but the 'RR" in the name has me confused.

Also, Dorman 521-679 replacement part is only listed as fitting the Right side, and they don’t make one for the Left.

Thanks.

The trailing arms are mirror images.
The horizontal lower arms are also different, but many aftermarket arms are interchangeable side to side.

Kilgore_Trout

Yeah, thanks for the reply. I was referring to the lower control arms, not the trailing arms. It's obvious that the trailing arms cannot be the same, but it looks like the lower control arms could be. You're saying that the stock lower control arms are different side-to-side, but some aftermarket companies have made them interchangeable side-to-side?

Thanks.

Exactly

edit:
the picture is of a eBay interchangeable side to side lca..

True, just put aftermarket lcas on my car and had no idea if they weren't different.

No writing indication on the arms themselves, so I would say don't worry about it. I haven't had any problems besides the bushings squeaking, lube them before installation, trust me.

Kilgore_Trout

Thanks for the replies. This is a daily driver/commuter car so I hadn't planned getting any aftermarket billet LCAs. I was just going to get OEM parts, or Dorman parts off Rock Auto.

What is still confusing me is microfiche is showing only one part number for the LCA assembly, and the required quantity is 2. That tells me that the stock ones must also be the same right to left.

Honestly, no, they are not the same.

There is a 'S' curve in the stock arms, they are mirror images and they are marked L and R, accordingly.

edit;
I have a extra pair of Del Sol LCAs on my shelf, and can take pictures when I get home, if you want me to.

Not the rears... I think I still have the 92-95 3 door rear LCA's spare in my stock room. I'll post pictures tonight after work. If not I can shoot pics of my wife's car as her's are still stock 3 door 92-95 rear LCA's.

If you have the Integra rear arms they are different due to the "s" curve as well as the rear sway bar bolt holes. And even that I am thinking there is no bend in the Integra arms. I'll have to look on my car as I swapped to them for a rear sway bar.

The 92-95 hatchbacks didn't have any of those provisions I'm 85% sure (100% on sway bar).

The fronts on the other hand have a slight bend to them and have both a left and a right.

I bought a used set of 92-95 hb arms last year to replace the crappy e-bay ones I had on my car. I run a progress rsb, so no need for sway bar holes, as the bar bolts up to the shock fork bolts. I did not find a left or right marking at the time. There was some leftover paint on the arms from way back when, so I thought someone might have sanded the label.

I remember putting them one above the other and saw no difference between the 2. They are unfortunately on the car now, so I cannot take pictures of them on top of another.

Edit: Then again, when I think about it, I may have picked up two lefts or two rights, so this comment may be irrelevant...

These LCAs were removed from an original, unmolested '93 Del Sol Si.
Note the L and R markings.

TomCat39

I will get photos of both the 3door hatch 92-95 rear LCA's and the 94-97 Integra rear LCA's when I get home.

I suspect the Del Sol and the 3 Door Hatch are different but in all honesty I can't remember them in my mind for the life of me so I could always be quite mistaken.

ejv8s10

I did a little online research.

First: both sides are available for the Del Sol, at Majestic Honda. Majestic Honda - The Internet's #1 Honda Automotive Parts Store
see picture.

I then checked a hatchback at Majestic, and they showed two styles: mirror image and interchangeable. Only the interchangeable being available.

I believe the mirrored ones for the hatchback that are not available you found are for the JDM hatches that received the rear sway bar. As you can see there is the bolt hole provisions for it.

If I remember previous discussions correctly, none of the north american hatchbacks ever had sway bars.

These first two photos are the rear LCA for a stock 93 civic hatchback CDM:




As you can see, no sway bar bolt hole provisions and straight as an arrow.

These next two pics are from a 94-97 Integra:




As can be seen, there is the sway bar provisions and there is a pretty strong S curve.

Matt_EH3

Thanks for the info/pics TomCat. I personally have the straight ones, so I feel better knowing that they are interchangeable and that I did not screw this up Yours seem to be lacking the L/R markings too.

Makes me wonder now why Honda went out of their way to create that curve on the sway bar LCAs. Maybe for better leverage on the rsb vs. the rsb attachment point?

Kilgore_Trout

Good Stuff. Thanks everyone!

The '92 - '95 hatchback trailing arms are the same from side to side. The sedans though, even the ones without a swaybar had a bend in them and are specific to each side, and I'm not sure why since they're interchangeable with the straight hatchback version. EX sedans had curved LCAs with provisions for a swaybar.
