Hey everyone,

The manual just says "Use the adjustment wrench".
Which wrench do I need?
Where can I purchase it?

I tried with a universal adjustment tool but it wouldn't fit.
My dealer wants $400 for a tool kit.
Appreciate the help.

This is what I use:

If you want to protect the anodizing you can wrap the end with aluminum tape, which should last for a couple of adjustments.

Here are a few.

I wonder how many of those tools will actually work OK on an FXS, or many other Zeros for that matter, without partial disassembly or shock removal.  If a bike's shock preload adjuster has fair access - as not one of my four monoshock bikes does - it's possible one or more of these type tools might be able to turn the nut enough to get onto the next slot, but I'd definitely check your bike first before buying one.  My drift punch works fine on all my bikes, needing only a 1" hole (or less) in the right spot.

All the Zero's use similar rear suspension setups, so one spanner wrench will work for all of them.  It's a tight for for the s and ds models, and for the FX and FXS, you need to remove the rear battery to get access.

So we're in agreement - there's one wrench that fits all the Zero shocks, and adjustment of those shocks using that wrench will be difficult.  I'll stick with the punch.

Are you using the big or the small end? Is it a proper fit or some other diameter is ideal?

I ended up using a massive screwdriver but I was really hoping there was a wrench that could fit the FXS without deconstructing it (since it has to have the full weight for proper adjustment).

I thought a hammer and a large flat bladed screwdriver was the right tool for any shock. ;-)

I'm going to try one of these:

The reviews are good (apparently it's pretty beefy), it concentrates force in the corner of the nut slot so damage should be minimal, and it looks like it can get into tight places and around corners a little too.

I have always used light tapping with a plastic mallet using a large screwdriver, but I am sure there are better tools.  However, since I don't carry passengers, I rarely alter the shock preload once set for my weight, so causing damage to the shock preload adjustment rings is not a big issue for me.

[MrDude_1]

If you use a large brass punch and a hammer you can rotate it without damaging the shock at all.

I personally have not had to do it that way, but some bikes require shock removal to set the preload, so I have watched other techs do it to their bikes.   use a oversize punch, and file the tip flatter to fit in the square slot.
