    weak shocks

    my p4de has the mm2/2650 combo and i use maxamps 3s batteries, with that combination it seems to heavy for the big bore shocks i am running. i have 50 weight oil and the stiffer blue springs from hot racing installed. the suspension stays almost fully compressed at all times. I seen some people have switch to the big losi shocks. does this work well? any suggestions, and if so possibly the part numbers to go with it? thanx

    The shocks dont hold the weight of the car up the springs on them do. Big Bores are fine for your truck you just need to find a stiff enoguh spring to hold up the weight of the car.

    You also want to make sure there is no binding in the suspension arms and links preventing the springs from rebounding as far has they should.

    Dad is spot on. It sounds like stiffer springs and adding preload is what you need. Here is a very informative video series from Jang @ Ultimate RC: RC Suspension 101 that really helped me figure out my suspension.

    I have a few sets of the losi Ten-T shocks and they are fantastic for the price.

    I read about a lot of people using the Ten-T shocks, they are definitely a good option!

    Yeah, I got big-Bore shocks with 50wt oil. They work nicely, but I need some stiffer springs. I run a cage on my Pede and it makes the truck heavy. Haven't been able to find any stiffer springs so far

    I use the progressive springs listed in the Stampede 4x4 parts list under Shocks: Ultra Shocks. These springs are available in everything from -20% (softer), through to +20% (stiffer). The springs not listed with a +/- rating are the standard springs on Slash 4x4. The reason you don't see a 'rate' is the spring gets stiffer as it is compressed. So the +20% springs are about 20% stiffer than the standard ones.

    My personal favorite setup is +10% progressive springs front and rear with 50wt shock oil.

    Now for the odd bit. If you're using the Big Bore shocks the body is a tiny bit smaller than the Ultra Shocks. (Not sure why, it just is.) This can cause the spring to sit at a tad bit of an angle.

    Simple solution: Use the ultra shock lower retainer for the bottom. On the top turn over the Big Bore spring retainer and slide the Ultra Shock retainer up against it. This gives the Ultra Shock upper retainer a nice flat surface to sit against and will keep your springs almost perfectly centered.

    Typically bottoming out after a jump isn't a bad thing. That's what the skid plates are for. Usually I set my vehicles up to run and handle well and let the skids to their job, they're sacrificial parts after all. The reason I stiffen the Pede up is I'm normally running 3s and reducing the body roll is super important at high speed.

    Yeah I just needed a little stiffer ride so I am taking your advice man and I do speed runs every now and again geared 15-17t pinion and 54t spur with a tenshock 4 pole 550 can and can be a bit skittish and it will help in the jumps too. I got them about 14 months ago and they are still in the packet so I know what I am doing in the next few days.Thank you tireslinger...peace

    I have the +20 progressive blues on my big bores and i have to say they are not stiff enough..... what you need to do is

    Click Right Here and Check These Out..

    I purchased these.. There is really not alot of spring options for the stampede this is what i ended going with... all the versatility in the world...to combine different spring rates for different conditions...

    What about these? Think these would fit on the big-bore shocks?

    http://www.ebay.com/itm/Traxxas-Stam...item5d42057241

    The reason why I asked is because I have [Traxxas 5862 Big Bore Shock Complete Set for Slash], The springs that come with it look like the ones suggested above... unless I'm missing something. I was thinking that the ebay link I gave would be stiffer. Thoughts?
