    1/8th shock spring setup for slash 4x4

    Hey group,
    Iím new here and Iíve searched prior to posting but Iím looking for recommendations. Iíve got an 8ish year old slash 4x4 hcg chassis that I dug out of a box after 5 years. Just planned to get it running but it snowballed into a mamba monster 1/8 scale esc, traxxas drag motor, mip drive shafts, etc. it is now obviously heavier and itís time for a shock upgrade. All of the posts Iíve seen about compatible 1/8 scale shocks seem to be considerably aged with recommendations being discontinued now. I know I could use proline but wanted to beef up to something larger. Any recommendations for recipes for success? This ad 17 mm adaptors and a new wheel setup should get me pretty solid, any recommendations for 17mm aluminum bead locks are welcome as well, preferably 2.2/3.0. Also apologies if this is incorrectly posted, feel free to delete if a problem r redirect as necessary. Thanks much!

    You can move it to the Slash 4x4 forums, here:

    That would probably get you more results.

    Traxxas GTR shocks would work great on your truck. Start with stock black Springs and 35 weight shock oil on All 4 corners. See how the truck drives for you then you can adjust your shock oil weights from there. I think this would be a good starting point for you. If you need a little bit heavier spring in the front/rear, pink is the next step up.

    I'm running 35 weight Losi oil with black Springs up front and 35 weight Losi oil with pink Springs in the rear on my truck. The suspension is PLUSH! It Glides over bumps and is very smooth on Landings off of a jump

    I agree that the GTR shocks are good. They are much thicker in diameter and are very smooth.
    Everyday's a gift, thus now is called the present.

    Appreciate that, didn’t realized I’d dropped this in slash v slash 4x4.

    I’d considered the gtr but didn’t know if their was anything better, was also thinking about getting a Losi spring tuning kit. Are there any issues with the plastic bits on the gtr?

    I don't think your weight has reached 8th scale level yet. If you start to get over 10lbs maybe then consider 8th scale shocks. The GTRs are not the best but they are the best for the price and should more than cover your needs.

    Are those of you running gtr running different length or rears all the way around?

    I was just looking through some of your posts and saw you’re running rear gtr out front with a jconcepts shock tower, if you don’t mind my asking, did that shock tower come with the necessary hardware for your shocks and if not what did you need? I understand you still need their body mount.

    No it didn't but I did use more parts. Originally Jconcepts sold a full kit with all the parts but I wasn't able to locate one to buy. So I pieced the kit together minus any of the parts for the rear. You don't need the caster blocks unless you plan to use the Monster Truck style rim and tire combo like MaxDee's build.

    I did add a Hot Racing spacer from a set I bought from Amain Hobbies to clearance the springs from the links.

    Ty for all the info, much appreciated. What are your thoughts on this route vs the oem rear shock tower up front. Obviously your method looks much cleaner but do you see any downside?

    I don't have the slash, but I have a stampede 4x4 with the slash hcg chassis. I run the appropriate GTR's on mine with VDK pistons drilled out to 1/16", 70wt oil and VG Racing dual rate springs. The springs are a bit stiffer as they sell them to accommodate the extra weight of their cage for the stampede.

    Springs: https://www.vgracing.com/product/GTR_Springs.html

    I just bash, so I wanted something to help take the sting out of a 10 foot drop while still being relatively cushy while driving.

    One other thing I did was to install dubro monster ends on the fronts after shaving the ball off the end so it was flat. This gave me 3-4mm of extra length on the front. The chassis still bottoms out before the shocks, but with the extra bit of length, it rides more level vs nose down. Also uses more of the shock on landing vs bottoming out on the front so hard.



    I've since replaced the RPM noodle arms with traxxas HD cold weather arms. They are a bit stiffer and let the shocks do more of the work vs flexing so much.

    I run a 4074 2200kv motor and 1/8th 150A esc. I usually run a pretty heavy 6200mah 3S pack in it as well. I also have MIP x-duty's, which probably don't affect the springs much, but they do add weight to the truck overall.
