Just picked up a lightly used eb48.4. Wanted to switch over my 8th scales over to Tekno and this buggy makes the final completion. It seems like the only upgrades these need are the Ti coated shock shafts. Am I correct in this thinking? I did notice that the NB48.4 like the front and rear universals. I am itching for our weather in the north east to break so I can get out and put some laps on these things.

I think it's just the TiNi shock shafts and of course an aluminum servo horn is always a nice addition when using high torque servos. The aluminum split center diff would be nice too which I bought but mostly just to keep less flex from happening in the center diff area.

Tini shafts are a waste IMHO.

Make sure you have the updated delrin shock cartridge set (Has a shorter hat on the bottom of the shock), Aluminum servo horn, maybe the full aluminum center diff. That's about all the ebuggy needs.

The .4 buggies come with universals. Depending on the track your at, you may want some CVD's for the rear, but leave front as Uni's.

What track are you going to>

I dont run at a organized track. I just love to spin laps. Good to know not to wast my money on the shock shafts. Ill look up the delrin shock cartridge. Thanks for the feedback.

Nothing beats a day at the track....Look at it like practice, but with marshals to flip your car over when you get it wrong.

so whats the story on these shocks...
is there a fix to keep them from building pressure or no?

Helps to know how your building them.

I run emulsion shocks, and set to 0 rebound, after several race days, I can fine them having 25% rebound. It's just the nature of the beast.

run them emulsion. Bleed them the start of each race day and maybe for the mains.

Honestly my shocks don't build pressure during the course of a race day. Mine build it from elevation changes when I drive to the tracks. I live at or slightly below sea level and in order to get to some of the tracks I'll hit 2000 feet above. My shocks will act like pogo sticks if I don't bleed them.

yeah thats shitty to deal with on race day...

If I travel a distance, and there's a temp change, I rebuild my shocks when I arrive anyways. but with emulsion shocks, you can cheat by popping the bleeder, and re bleeding the shocks on the vehicle. I'm lazy, and this is my normal way of doing things. LOL

Isn't the bleeding process stupid simple to do? I have yet to do it on this buggy but I imagine it'd only take a few minutes right?

and everytime you do this you remove oil.
if you remove some oil then you have more air in the shocks causing the issue to continue and get worse as best i can tell.

it's 4 small 1.5 screws. You don't even have to take the shocks off the car. You're just letting the air pressure inside equalize with outside. You probably won't even get any oil to come out.
