Limiters on shocks, when to use?

I have read some info that using limiters on the shock shaft that is outside of the shock body is useful to control bottoming out.

Has anyone does this for that purpose and had any issues when doing this? ( ie- damage to shocks, etc ).

I am considering doing this for my buggy.

I have found it quite poor at this, hard limiters especially. one shock normally hits the stop before the other sending the car off to one side. rubber 'o' rings might be OK.

the only time I would consider using them is if the up travel is too much so that something on the suspension catches (driveshaft or something similar)

as long as your oil/springs/pack is right then a little bit of bottoming out is not really a problem, when on some bigger jumps your car normally takes off with the chassis grounding out anyway

Thanks for the info.

I am still trying to get used to bottoming out as something that does happen. when running indoors over jumps bottoming out was not something you did but to get around the track compromises in suspension are needed.

I may try that o-ring thing.

O-rings or small pieces of fuel tubing could help soften the blow. Unless you're jumping off of tall drop-offs, then bottoming out won't really hurt, and you'll cause more damage by trying to stop the chassis from hitting the ground.

Use a Losi shock dyno to make sure both shocks are the same length when compressed!

Default external o-ring limiters

I alway thought they are for controling body roll rather than helping out landings on the jumps.
In fact you only bottom out easier using um >(Less shock travel)



Way better to add pack & ride height for landings ...

Try unscrewing the bottom shock eyelets a few turns....

The thing is I am trying to cut down on bottoming out the actual chassis, so basically it doesn't smack down as hard.

The track has a few huge jumps, with some medium jumps and the straights that make the suspension work for it. So alot of guys run there vehicles pretty soft and you can sure see it when you look at the bottom of the chassis.

Add pack....

go to a smaller piston or a higher weight oil....

The reason the other`s are soft is for traction & a smoother ride....

if I were you, first try adding ride height before anything....

add pack( smaller piston) for big long jumps with hard landings....

Also try going all the way inside on the shock tower, gives more shock travel.....

If you try the pack ...


go to a smaller shock piston....and use a thinner( 5w less) oil.

Right now for handling around the track, I have too much pack, ride height is not an issue.

I am going to try what the others are doing and see how it goes.

Thanks again guys for the info!
