as it sits it’s really high and wide. shocks are 98mm. some 90mm would fit better and make it sit lower. the width i don’t think could get much narrower. maybe some low offset wheels? method 101 with 225 hubs would be close to the same width im at now

2.2 wheels look to be the way to go then. Any sand, mud, debris would get stuck.
 
That does look a bit on the tall side, and those 4.75"s actually look big on there, in a good way of course. I threw some Jconcepts shock limiting spacers on my order that showed up today, so I'll for sure be limiting from the get-go. Maybe I'll just start with 5mm.

What's your clearance under the diff?

top shaft ax123013 does not fit through the case as shown. the flange part is what the whole slipper assembly sit against. im not certain if the shaft can be put in from the other side. as shown it will not go together. i enlarged the hole in the case so the shaft would fit through and the slipper pad would fit against the stepped up part on the shaft
 
Everyone keeps saying the thing sits high and they want shorter shocks to lower it? What is your guys reference point to consider it high? I mean the links at ride height are level, and dropping the ride height lower would defeat the purpose as the skid would sit lower than the axles...

Can someone so an non portal rig on 2-2’s alongside a Capra on 1.9’s to compare under axle clearance and skid height?
 
Almost finished building mine. Was a little disappointed that I couldn't gear down with an axial branded 11t pinion. With how tight the motor clearances are it won't slide over enough to get proper gear mesh. Doesn't look there is much room for larger spur gears down the road either, so the gearing options feel pretty limited.

From what I've seen a lot of people are putting big brushless power in theirs so this might not matter to most, but I was going for high torque, low speed crawling.

Oh well I'm still super excited to get it out on the rocks today!

Your links seen angled. The Axial page shows the links level which is ideal so I’m not sure why yours would be different.

this is rtr. as it sits now i put 1/4” limiters on the inside and shorter element springs. feels way better.

Nailed it! Thats exactly what I had in mind. Stance looks great.

This could be another "crawler nOOb" question (again, I'm more familiar with off-road track racing), but why not just use the limiters, along with the stock springs? This would create 'preload'...unless preload isn't wanted in crawlers.

With my race vehicles, I'll typically place 1-2 1mm limiters (usually silicone, but occasionally rubber) inside, to shorten overall length...but, I'll also place a 2-4mm length of silicone tubing on the shaft outside the body, which not only limits upward movement, but also acts as a "bump-stop". The first, obviously, shortens the overall shock length, while the second prevents the shock (and, thus, the vehicle) from "bottoming out", while also softening the "end-point" of compression (should the shock completely compress, such as during a hard landing).

That's more like it! So the manual doesn't suggest internal limiters?

I wonder if Rich's build is using internal limiters inside the shocks.

By limiting shock travel you lose articulation. Sometimes not an issue, too much and it is. Too much articulation can be bad as well. Depends on the terrain. You may want a tire to float across a gap instead of into it then potentially cause a rollover. Too little articulation could also cause a rollover. I prefer, for my area and style, around a 80/20. 80% sprung and 20% droop. When I pick up my rigs you can feel the axles drop down a little and the shocks top out.

My race vehicle are somewhat similar, probably ranging from 85/15 to 80/20, depending on the vehicle type (well, except for my XRAY T4, which is probably closer to 95/5...but that's a TC chassis).

How terrible are the drivers in your area to think so little of them and their rigs?:shock:

It's more about the guy driving the stock Capra in sporty than the caliber of other drivers. I've seen him drive ridiculous lines with just about every rig out there.

Odds are I'll put ar44's under it and use the axles under something else anyway. :lol:

The trans doesn't have enough reduction to run standard axles. Almost half the overall reduction comes from the portals.
