Are there any shocks out there that fit my "Would like" requirements?

Just measured quick and dirty(so I might be off a few mm's):
LST2/ Aftershock shocks:
pin to pin: 146mm, compressed: 106mm
shock body diameter: 25mm

Muggy shocks:
pin to pin: 133mm, compressed: 104mm
shock body diameter: 25mm

Cen gst 7.7 shocks:
pin to pin: 143 mm, compressed: 115mm
shock body diameter: 17mm (piggy back shock)

edit: I snapped a Muggy shock shaft yesterday. They're notoriously weak. The LST2/aftershock ones can be upgraded with TiNi coated shafts(as mentioned before). You can find plenty good deals on these shocks on ebay. The plastic aftershock shocks will be cheaper than the alu LST2 ones.

losipartshouse.com had their losi 8t roller on sale for $320 brand new. just saw it a couple of days ago. they might still have some. but that is a steal. i paid nearly $600 for mine like 2 months ago. not the 8t 2.0 just came out.

jayjay283 01.11.2009 01:01 PM

some how some way that ofna will be mine Brian :lol:

Thanks for getting those measurement! Saves a bunch of hunting around the net.

I guess I should have mentioned that my diameter measurements were including the spring. :oops: I updated my list above accordingly. The LST shocks have the length and throw I want, but may be a hair too wide with springs. The GST shocks are the same diameter and approx throw as the 808, just longer. The Muggy surprisingly doesn't have the throw I though they would.

Hmm, still nothing that suits me perfectly. I could probably use the stock rear shocks and make an tower extension plate to allow for greater ground clearance.

Or, you could simply get an Ultra GTP and convert it. Most of mine was made using RCM parts (battery tray, motor mount, motor, ESC, etc). The only custom things were the top plate and modded radio box.

jayjay283 01.11.2009 02:20 PM

well the whole issue is, the ofna used to come with a 2 speed, which is a $99 part, now its 1 speed, not that I want the 2 speed, but I feel raped if I buy it lol. So just give me yours and lets save us headaches. Sooner or later it will be mine lol

BrianG 01.11.2009 03:46 PM

Well, EVERYTHING has a price if the buyer wants it bad enough. This isn't a FS thread, but just for giggles, the GTP is yours, minus servo, motor, ESC, BEC, and rx for $1,000. :smile:

jayjay283 01.11.2009 03:49 PM

a thousand dollars, OK but i want the servo motor etc ? no f/s thrad just playing, but iffin ya do want to p[art with It lol

BrianG 01.11.2009 05:48 PM

lol, yeah. If you change your mind. :whistle:

Seriously, after running the two speed with mech brakes and no reverse, I MUCH prefer the single speed setup. It's simpler (wiring and lack of servo/linkages), and I NEED reverse.

TDC57 01.12.2009 03:00 AM

Just an FYI!!!! :lol::lol:

lets see it!!:yes: or least post pic on your site.. throw us BONE...:whistle:

BrianG 01.12.2009 10:58 AM

Lol, you wanna see pics of a stripped down truck? I usually save the pics for the final product, or at least stages where stuff is made. Don't worry, there will be pics. :wink:

So, no one know of any shocks that will fit my requirements:

135-140mm long full extended (hole center to hole center) to 95mm fully compressed (40-45mm throw). From 24mm to a max of 34mm diameter including springs.

If there was enough data like this, I'd add a "shock data" table to my site. A lot of people do custom stuff and it would be nice to have measurements for a bunch of different shocks so we can get an idea what fits. Heck, I may just start one with what I have and let people submit their info...

YES!! Yes we do.. :lol::lol:

After all you suffer through all of our builds at there many different phases so it only fair you return the favor..:yes:

Have a great on Brian..

BrianG 01.13.2009 01:19 AM

lol, too bad! You're just gonna have to wait. Besides, if you want to see a stripped down truck, just go to any other XT8 thread. :smile:

This setup is gonna be my typical thing: top plate/brace (like the GTP and MBX5/Corr); 5s battery on one side, Neu on the other; some type of custom rx/BEC box; and probably just get the MMM combo. Nothing special really. And yes, I'll be using an external BEC even though the MMM has one - I still don't trust the built-in one...

jayjay283 01.13.2009 02:01 AM

still not trusting the v3 bec ? Im still rolling 2 v1s and a v2 and no problem what so ever...I emailed CC to trade them in for V3's but I dunno they work fine so why lol

BrianG 01.13.2009 11:02 AM

Yeah, I know. IIRC, I haven't seen any V3's with BEC failures yet, but I'm just looking at the design, location, etc. Besides, it won't hurt anything since I already have a few BECs laying around here anyway.

TDC57 01.31.2009 03:06 AM

:whistle: Any new updates Brian :neutral:

BlackedOutREVO 01.31.2009 03:17 AM

Leave the 808 shocks on the Xray. Would be stupid IMO to change them. There some of the best shocks made!

PICS!

BL_RV0 01.31.2009 12:45 PM

Pics now. :diablo:

BrianG 01.31.2009 12:46 PM

No, no updates yet really. Did some custom stuff, but still waiting on parts. Just ordered an RCM battery tray, MMMv3, and a Medusa 36-80-20-2000 last night. I was gonna just get the MMM combo, but a 2200 motor on 5s is a bit fast on this truck, even geared 48/12.

The rear shocks are still up in the air. The 808 shocks will remain in the front, but the rears need something with a little more travel. This is being set up as a basher, so it's gonna sit up higher and the extra suspension travel is required.

Be patient, when it's done, pics are sure to follow. But really, it's nothing special - just the typical truggy setup, and when you've seen one, you've seen them all...

jhautz 01.31.2009 06:39 PM

Cant yuo just put the rear shocks in the lower holes on the shock tower to get a little extra suspension travel?

BrianG 02.18.2009 10:02 PM

OK, conversion is complete! I got the roller from another member here. Pretty good condition and included a bunch of new spare parts. Where needed, I got new stuff here and there.

Nothing special about the conversion, just the usual fare: RCM motor mount, battery tray, MMM, Medusa 36-80-2000, 5s2p 5Ah lipos (Mike's), my usual stiffening custom top plate, Spektrum DX3r, geared 48/12 for ~36mph.

At a suggestion from Dafni, I ended up using big bore shocks from the Jammin X2 Truggy kit. I didn't get quite as much suspension travel as I wanted, but still quite a bit higher and suspension is stiffer than your typical race truggy setup. But I wanted this to be more of a basher and will occasionally play at the track, but I doubt I will ever race it.

With 120k in the CD, it wheelies nicely, but not so easy that I can't get on the throttle.

OK, enough talk, here are the pics:

rawfuls 02.19.2009 12:29 AM

Pictures aren't working for me..
Anyone else seem em?

jnev 02.19.2009 12:32 AM

I see the pictures. Nice set up Brian and very clean install as always. That piece going across the length of the chassis above the center diff... is that to minimize chassis flex? Or will something be mounted on top of it?

rawfuls 02.19.2009 12:33 AM

What the.
Awww, looks like my internet is dead now.

It feels like it's dying.

Grr, time to restart the router...

Thanks. :smile:

Yeah, the brace is to reduce chassis flex. In my buggy, I noticed the chassis begins to resemble a taco after a while, and this helps tremendously. I've done this in my Ultra GTP and MBX5/CORR conversions and it helps a lot. I don't plan on installing anything on this project, but I put the ESC on there in my GTP and MBX5.

Some may argue that the chassis is supposed to flex and helps traction, but I'm more of a basher/informal racer, so that level of detail is wasted on me.

rawfuls 02.19.2009 01:30 AM

Fixed it.. I hope.

Nice rig!

I'm jealous.

Makes me want a truggy.....

BrianG 02.19.2009 01:36 AM

Actually, ever since I sold my converted Revo, I've regretted it. I miss something with big tires that I can go over curbs and such. So, if I figure if I was gonna get a MT-like vehicle, I might as well get something with a proven platform and strong components. And a truggy fit the bill perfectly. Took a bit to find the proper shocks to get the suspension the way I wanted.

rschoi_75 02.19.2009 01:37 AM

Sweet Brian. Very clean!

I like the chassis brace. Are you using that in conjunction with mike's brace that goes under the center diff? Also, would you be willing to make me one for my xt8. I use mine as a basher too, and any added protection would be great.

btw, are you still using the grey springs? I'm using the ofna big bores too and I found that the blue "hard" springs are very nice for bashing.

BrianG 02.19.2009 01:41 AM

Well, I do have a brace under the CD. I didn't realize it was Mike's brace - I thought the XT8 came that way. :neutral:

I can make another top brace, but I would need the vehicle because I don't want to take mine apart again for test-fitting. Also, much of my work is "by eye", so things aren't always perfect. If you don't mind the "risk" of mailing both ways, PM me and we can work out the details. It'll take a couple weeks though because I don't seem to have the same amount of spare time I used to (new baby and all).

rschoi_75 02.19.2009 01:48 AM

ohh.... I didn't realize it would take that much work on your part. I don't want to add more stuff on your plate since it seems you have your hands full right now. Thanks for offering though. Much appreciated.

I love the idea though... I will definitely try to make something similar.

BrianG 02.19.2009 02:02 AM

They're not hard to make really, just time consuming without the proper tools. I start by cutting the rough length. Then I drill the 4 CD holes where it should go. Then I trim the sides with a hacksaw and file/dremel until it looks pretty. After that, I make the slight bends so it sits flush with the F/R diffs. Next I cut the ends off and drill necessary holes. Finally, clean and paint.

bdebde 02.19.2009 02:39 AM

I don't see the pictures???

Hardstyle 02.19.2009 11:49 AM

Works for me. Nice truggy BrianG :great:

BrianG 02.22.2009 05:55 PM

Wow! That's it in a nutshell.

I just came in from testing this rig outside. If all truggies handle like this, why is there even a market for monster trucks? This thing handles awesome, even the way I have it set up for higher ground clearance! My Revo NEVER handled this well! And I should mention there are no sway bars installed on this.

And the suspension? Perfection! This thing handles jumps, even high ones, with ease. No bounce, and no chassis slap - just pure smoothness. These Jammin X2 shocks are just right.

The CD filled with 120k is PERFECT! Wheelies only when I want it to, otherwise, just takes off like a scalded cat.

The Medusa 36-80-2000 on 5s ran perfectly. Granted, it was around 30* outside, but I don't think it was even 30* above that. Plenty of power too.

I'm using Mike's 5s2p 5Ah lipos and they worked beautifully as well. I have no idea how long I was out there, but when they dumped, they dumped. There was no "wait a few seconds for the voltage to rebound so I could drive it to me". When I put them on the charger about 10 minutes later, the pack was at 16.5v (lvc set to 16v or 3.2v/cell). It only took 800mAh before the voltage was at my storage level of 19v. Man, I love these.

So, in case you can't tell, I am extremely pleased with this setup.

BrianG 07.13.2010 03:07 PM

A bit of an update on this truggy. My XT8 has pretty much been reduced to towing duties, lol. One day, I was curious whether it could easily pull a wagon with my daughter in it. Here is a vid of the trial run:

<object width="400" height="266" ><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="movie" value="http://www.facebook.com/v/1427795334531" /><embed src="http://www.facebook.com/v/1427795334531" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="400" height="266"></embed></object>

The problem is that she LOVED it. So, we go out a few times a week around the neighborhood. I geared down as low as I could go and it runs great. Stays quite cool considering the load. I get sooo many comments from people asking where they can buy one, lol.

Just last night, I went 3.6 miles on one 5s 5Ah pack traveling around 3mph. And a guy in his old Toyota pickup stopped alongside and we chatted for a bit. When he expressed his surprise that it had enough power to pull it, I told him not only can it pull it, it would also beat his Toyota on acceleration. He thought I was full of it until we proved it. I only made to about 15-20mph since my daughter was in the wagon (she loves it when I go fast), but that shut him up! :smile:

bdebde 07.13.2010 03:12 PM

Awesome!!:yes:

blueb8llz 07.19.2010 08:55 PM

what? you mean you took off on that pickup truck with that wagon and daughter still hooked up??? i wouldnt have believed it as well too hahah. how the heck is that possible?
and that buggy pulling your daughter can reach speeds up to 20mph? that is pretty darn fast if you ask me haha
