Has anyone done this yet? I just got a set of MBX6 Shocks off of Ebay and I was wondering if the Springs are going to be too soft and what weight oil I should run in them for the Truggy.

I think there HoeBay truggy big bore springs that will fit.

I sold a set of MBX6 shocks to a buddy of mine in Vegas. He installed them on his MBX5T. He used Kyosho springs but had to cut off a few coils on the front springs since the Kyosho STRR shocks are longer. He is still playing with them.

Thanks Tony I was thinking the same thing. Do you know which st-rr springs he used. I see most of the trucks at my track are using the blue ones. Not quite sure what stiffness those are. What about using the buggy blue springs in the front and the truggy springs in the back?

I think the front springs were light blue. I don't think buggy springs are stiff enough for the heavier trucks.

My current MBX5T runs Kyo BB buggy shocks with buggy blue springs. It works fine. The MBX5T shocks are about the same length as the 777 BB shocks. The ST-RR front BB shock and springs are much longer than the MBX5T can use. Also given that the same wire size spring with more winds is softer than the same spring wire with less coils.

Jammin springs are both a LOT cheaper and slightly larger in diameter. I tried putting Kyosho blues on my Jammin truggy and had some slight binding between the spring and shock body. (Jammin and Kyosho shocks are both 16mm inside, but the Jammin shock bodies have slightly thicker walls... just enough to make that bind happen.) The Jammin blue springs are pretty close to the Kyosho blue ones in stiffness, but I think a bit shorter (not positive on that.) The Jammin springs would probably be a slightly better choice for you.

I would say the Mugen MBX6 springs are the ones to use, since they are for threaded shocks. The Kyosho ones are most likely smaller by a tiny bit.

I got my shocks the other day and I put them on the truck. The front springs feel great, but the rears are lacking the stiffness I am Looking for I had to crank the adjuster down about 14mm to get the ride height to be level in the rear. I believe Mugen has release the option springs, but I am not sure yet. I will have to look. The shocks mounted right up on the truck with no mods needed at all.

the stock rear MBX6 spring is a 10.25T spring. There is only one stiffer spring and thats 10.0T. A longer spring will add some preload height, but will not be any stiffer. If anything, they are softer.

I have a set of the Mugen hard springs on the way. I figured I would see if they would work or not. I would like to not have to run another mfg springs if they are going to rub on the housings. What weight oil do you think I should run in the shocks?

nick,

let us know how that works out.Should have some big bores in a couple of weeks

I would say try 450-500 in Mugen shocks with 5 hole 1.35 pistons. Since I used the Kyo BB with 6 hole 1.3 pistons, I used ST-RR weights 700-725 and it works great.

I ran my 5T last year with the Jammin big bore shocks and the jammin blue springs. It worked way better than the stock shocks and red springs. Front/rear spring combos such as the font/rear jammin blue spring are designed for the jammin truggy and you neeed to be lucky to get to work right on another car. They are softer than the reds. Our tracks are always bumpy and blown out so the softer springs work better around here. For stiffness they are inbtween the mugen grey and red springs. The jammin shocks are slightly shorter than the 5T stockers. I found the limitted droop helped it turn and roll-over less.

I was thinking the same thing. I am going to try Mugen 500 for starters and go from there. I hope to get it out on the track this weekend.
