Springs for the big bores

[T Virus 01]

I just got me a shiney new set of big bores for my E. I love these things, they are smooth. Anyway, what would be a good spring to get to stiffen them up some. I used the shock oil in the package & well it didnt work to well. I have to use a lot of spacers to get my truck to set right. What weight shock oil would you recomend along with springs. I run mostly in loose dirt so flipping in turns is not a problem. So basically I'm looking for a good shock set-up to handle large jumps.

Thanks Jang. Great site you got here.

Thanks for stopping by, T Virus. The oil that comes with Traxxas shocks is 30wt -- ridiculous for this truck. If you're running 2-hole pistons (I think that's the factory default), I'd say try something around 60wt, and put one stock red spring and one Losi 2.5" blue spring at each corner and see if you like that.

If you have a lot of aluminum hop-ups in your truck, you may need to increase the shock oil weight a little. The above should be a good starting point, though. If you try it out, let me know how it works for ya.

I run progressives now but, I use to run 70weight with losi's BLUE spring made for the E and the T. The also have a BLACK extra-heavy spring

[The JANG]

Cool. Let me know how those work out. Do you know what rate (lbs/in) they are?

Through much trial and error I have come to the same conclusion as Jang. For racing I use 70wt oil, 2 hole pistons, one red(stock) and one Losi Blue at each corner. I am not a great racer but this works best for me. I also put about 9 or 10 mm of shims all around to lower height. I only post this re-hash of earlier info to confirm that someone else uses this set up and it works well.

ok i tried out what u guys said about the losi and heavier
wt oil works good on corning but i bottom out on jumps
Jang do u have this problem?

[The JANG]

Any truck will bottom out, and actually should to absorb the impact of really large jumps. If it's bottoming out too hard, though, first try adding more spring preload spacers. If this is still not enough, try even heavier weight oil (try 80 or 90 next).

i wouldnt say it was exsessive doesnt happen all the time thanx jang

[Bob The Gamer]

what site sells the big bores?

[The JANG]

TowerHobbies.com is where I usually get mine.

Has anyone tried the springs from RCRaven? They also have some dual rate springs that are 7ppi at the bottom! I think that is what is needed for my all metal maxx.

[The JANG]

Yep I use them on my Valkyrie -- one at each corner next to some roughly stock-rate springs. This works pretty well, and the Valkyrie is 15lbs (heavier than any T-Maxx, no matter how much metal you put on it). I think they're supposed to be 3lb/in at the top, but that's simply inaccurate -- they're extremely stiff all the way through.

Most folks run them like I do, one at each corner with a more reasonable spring next to each.
