Setup Sheet Shock Rebound Percentage

[pmes]

So after building the shocks, I jack the shaft in and out several times, push it all the way in and let it go. Is the amount the shaft comes out by itself compared to it's full travel the number of rebound percent I put on the setup sheet?

Yep.

Is there anyway of making sure you get exactly the same amount of rebound on each shock?

Use the same technique for each shock. Method I usually use is:

1. Full shock about 90% full
2. Gently move the shaft up and down to get rid of any excess air
3. Top the shock up with oil to the brim and so it balloons up
4. Put the cap on and tighten
5. Undo the bleed screw and slowly push the shaft to the top
6. As soon as the shaft hits the top tighten the bleed screw immediately.
7. Pull the shaft back down to the bottom
8. Undo the bleed screw then tighten it back on

Repeat for each of the shocks and you should have a similar abount of rebound

If not, then play about with how much air you have in the shock by bleeding it gently when the shaft is pushed in

Thanks. What affect does more or less rebound have on the car?

Hi Guys,

Do you always make rebound on your shocks ? The 1:8 buggy drivers mainly make it,,, as I know

I wanna make it on my 2WD,, why not. Since now I eliminated the rebound effect, but maybe it will helps to increas packing and will react quicker on bumpy sections.

Please correct me, if Im wrong.

many thanx

Yes you are correct mate.

I find with no rebound the shocks feel dead. Some rebound helps the shocks come to life and react quicker.

It also generates a more progressive pack, the further the shock is compressed the more pack it will generate

[Japaps]

Is there an optimum amount of rebound, 25% for example, or is it very specific to the track conditions?

[Hulk]

I build my shocks in the same way every time, always having between 20-25% rebound for all tracks.

As i say, no rebound makes the shocks feel dead which is never a good thing on any track.

Cheers, that makes things nice and simple.
