Has anyone replaced struts on their TSX V6 model?
I installed KYB Excel G's on my 03 TLS a few years ago with great results.
Unfortunately KYB only lists replacements for the TSX 2.4 Liter model.
The struts on my car have seen better days. No need for expensive replacements as I use this car as a daily driver.

 

I highly suspect they will work. I can't see Acura changing the geometry of the car to the point where using the I4 suspension (OEM or not) in the V6 wouldn't be plug and play. Of course, I'm no expert, so you may want to research a bit more.

With that being said, the suspension components between the 2010 I4 and V6 models are very similar, but not entirely the same. Maybe they're actually one and the same, but the V6 simply features a higher price tag as it's supposedly more "premium" of a trim? No idea.

Now, my intuition may be entirely incorrect and perhaps they're not plug-and-play swappable. Few things you can try: ask other aftermarket suspension companies whether their coilover kits fit both I4 and V6. If yes, you may be in luck. If no, the idea isn't completely out of the water yet. Most of these companies aren't from North America, so a V6 model likely doesn't exist where they R&D'd their products. To lower the amount of liability, the company could simply throw in the towel and say V6 isn't supported when it very well could be.

Another thing you could try is check out some of the V6 build threads here. I'm sure at least one of them here have a coilover kit installed. It likely only says it's compatible with the I4.

Good luck

 

The V6's weight and its distribution is different than the L4, which is the likely reason for a different damper design. While they may physically fit, they are probably internally different.
I would not recommend using L4 dampers on the V6

 

Geometry has noting to do with the application. The internal valve design of strut is what makes the difference. The heavier V6 requires a different valve rate to dampen the suspension.

I'll approach it from another angle and say that I'm nearly certain that a company as large as Honda, who has embraced manufacturing efficiencies (Lean, Kaizen, etc.) to the extent that they have, would not maintain two individual part numbers for an identical part.

If the struts were functionally identical, they would carry the same part number. Now, they might be dimensionally identical and might physically swap over, but as was previously mentioned, there are mechanical differences in operation.

So TL;DR, if the PNs are different, you might be able to fit the parts but they won't work the same. That's generalizing a little bit, and there might be an exception, but it should be true for most cases.

 

Oh, and I guess I should say that was in regards to Honda using the same part for the v6 and i4 but labeling them with different part numbers.

There is always the chance of cross-model comparability... You could pull the v6 PN and cross reference it across the Honda and Acura model lines. If you find a match, then see if the aftermarket part has that application. However, most companies have already done that and will point out that the part fits multiple applications.

Short answer is still i4 wouldn't work on v6.

 

I agree. Merely suggested that the I4 suspension components are likely plug-and-play with the V6 model. I do agree putting the stock I4 into a V6 likely won't function as well because the V6 dampers/springs were designed for a nose-heavier car.

 

Honda is very particular about damping and spring rates. The 1G had different PN's for auto and manual cars, for example.

I'm positive the V6 has a different shock than a 4 cylinder. It can be confirmed by checking the part numbers from Acura.

Some aftermarket parts will cross over if the damper is set to handle both spring rates...or if the damper is adjustable.

They do not share the same damper valving, however.

 

V6 owner here...I discovered the v6 accord I believe 8th gen uses the same exact suspension as the v6 tsx. A coworker of mine had coilovers on his accord and upgraded to an air system so I bought his coils and put them on my tsx.

I blew out my front left coilover due to a massive pothole and when I called the company (megan) I inquired about the replacement. In specific I asked if the coilover system they sell is a universal application for all 2g tsx and 8g accords and they told me the weight difference was Minimal (v6 to 4cyl) when taking into account the increased spring rates and the adjustability of dampening.

I have had the coils on for about 6 months now and I think I have the car dialed in the best I can for daily driving.

If you just want new shocks you can buy some oem accord v6 ones as they should be a direct fit.

I couldn't stand how sloppy the stock v6 suspension was on the tsx. This is subjective to each driver but I love the adjustability of a coilover system and I'm happy with my current setup. Plus the shocks are relatively cheap to replace at 130 a piece and are way easier to disassemble compared to the stocks.

Good luck with whichever route you take.
