The Koni Sport Yellow Shock & Their "Height Adjustable" Nature: Don't Put Too Much Stock In That...

Koni Sport/Yellow shocks provide a broad damping adjustment range and will accommodate a broad range of springs.

In many applications they also feature numerous snap-ring lands, or grooves, in the bodies, which allow for movement of the spring perches. Moving the perches up has the effect of raising the car, and moving them down lowers the car.

So, naturally, many people consider the Koni Sport damper as a "height adjustable" part. I think even Koni promotes it this way. So it must be!

We at Heeltoe use a lot a caution when calling Koni Yellows "height adjustable."

Most people don't realize that the awesome Euro-tuned Koni damper is also rather IKEA-like from an external standpoint (just look at the instructions...sheesh!). The perches can be moved to varying degrees but a cautious observer notices that the fronts (for the 3rd gen TL application as an example) have two height settings and the rear has three (!).

If Koni made these dampers to be height adjustable why would they not allow the same range of adjustment on both the front and rear? And more than that, the rear ring-land spacing is not always evenly spaced. Why?

The reason being, in our estimation, that the Koni Sports (Yellows) are broadly used across varying applications and this adjustment is needed to accommodate different installations. The adjustable valving allows them to use the same front dampers on these Honda and Acura cars:
2g TL, 3g TL, 2g CL, 6g Accord, 7g Accord, 1g TSX.*
The rears are more focused as fitting the 3g TL, 7g Accord, and 1g TSX with the earlier cars having a different part.Likewise, the rear dampers are supplied with spacers to allow them to fit the different rear hub carrier dimensions (because TL/Accord is wider than TSX).
Don't forget Accords come in all combinations of I4/V6 and 2dr/4dr.

The different height levels of the Konis are there because these dampers can be adapted to various pre-load levels to compensate for the loads these different cars have on them. We believe this because when installing Konis on all these cars you will note that the standard dampers' spring perch heights moves. So to set a car at "stock height" you pick the perch height that corresponds with the stock damper. 

So why not call that a "feature," MrHeeltoe?

Simply because not everyone is going to derive benefit from moving these perches in the same way. Say you install the dampers to the stock levels on your car and decided to lower it front and rear because the spacing of the perch settings allow you to.

Then you go blab to your buddy about Konis being height adjustable, then he gets them for his car and finds that the combination of perch settings he has to work with don't allow a level height change.

It might be a semantic but here at Heeltoe we try selling parts as responsibly as we can. A misunderstanding in a forum bout has no accountable party. But we must be accountable to our customers for every sale and strive for the happiest customer.

So when we sell Koni shocks we tell people to pair them with the lowering spring that best meets their lowering needs. And if they really need height adjustment, they would be better off getting a threaded body coilover kit.
