Traxxas Big Bore in 80mm?

Portal axle clearance to frame is exactly the same as standard with same shocks, that is why he wants 80mm, to bring chassis down to match overall height or COG to a standard axle with 90's

How does a spacer inside lower ride height without sitting on the spacer itself? In order to lower ride height from inside, the spacer HAS to be taking up all ability for the shock shaft to extend, AKA zero droop.

It doesnt always have to sit on the spacer, mine with softer mini t springs at rest is still in droop. He was asking how to mod for an 80mm out of a 90mm. I guess I was assuming he was planning on tuning the springs

Wrong, that is exactly what I posted above yesterday.....

There are two reasons I did this. One, as mentioned is to get an 80mm with a very nice shock that they do not make. Two which is the big one, is to maintain a low ride height for sidehilling or climbs, instead of going with a really soft spring on the longer shock. It prevents from getting a bunch of unloading and some wonky COG setup. Just raising your shock position does not change how much it will unload, it will still unload a full 90mm, you need to limit it. Its a great way to tune a performance rig but not always for everyone. I like my comp rigs planted, dont need much flex at all.

So you're NOT using spacers to adjust ride height as previously suggested, you're using springs

Listen you are making this really complicated when it is not. The OP asked how to shorten his shocks. The length of a shock is its total extended length. Placing a spacer under the piston inside the shock body reduces its total extended length so results in a shorter shock.

And that's exactly why I'm offering more information.

With just that advice alone his trucks ride height will be higher than necessary and more than likely have collision between axles and frame.

If the proper solution of spring weight tuning and understanding suspension is to complicated for you, feel free to block me, I'm not here for the elitist attitude crowd, I'm here to help, learn and share

Traxxas makes (possibly made, not sure if still in production) a 80mm shock
TRA2659

I would recommend ordering a rebuild kit with them as mine the bladders were dried up.

Almost.... youre getting warmer quoted from above. You are setting a max ride height keeping a lower COG on sidehill, off camber and climbs. Just a softer spring will not keep the rig planted as well.

Even if for some reason he just used a spacer and the stock spring, it will not result in taller unnecessary ride height, EVER. Higher chance of collision, of course, but still less than if you raised the shock mounting mount point and, just going to a shorter shock on any rig will do that.

Well, if youre here to learn, dont let ignorance and pride get in your way. Not sure how else to slice this or what youre missing. I guess without the experience you will not see what it does. This or limiting straps is the best performance way to do it. Softer springs can get you the same ride height, but will result in excessive unloading. Like I said, its not for everyone.

Interesting, so taller shocks don't equal a higher ride height.

No pride or ignorance here mate, I'm playing with toy trucks at 41 which I'm about to go do and enjoy my ONE day of sunshine FML.

Cheers!
