    GPM Aluminum Shocks any good?

    hey,

    did a search and couldnt find anything. so my question is are the GPM Aluminum Shocks any good?

    - do they leak?
    - how stiff is the supplied spring (and they equal to tans , blacks ,etc)/
    - are they well made?

    and if they aren't any good what are some good shocks?

    From my experience with GPM on other cars, they make very high quality stuff.

    Can't tell you anything else though.

    Yeah, I heard that about the carriers. =(

    My wife bought me the Blue Alum. GPM Shocks for X-Mas.

    Gunna empty out the oil & refill with a little stiffer weight & green slime the o-rings, just cuz I bought the stuff for my stockers and it seemed to help. =)

    I just recieved my GPMs and haven't had a chance to install them on the truck yet, however the machining is top notch! I have no clue how China can make parts for so cheap!

    I dissasembled one to inspect it and the shock oil felt a little thin for me, and there seemed to be more friction/stiction in the damper than the stocker. Does anyone know the oil wieght that comes in the GPM units?

    Yes Excellent product. By far the best shock option part for the MERV.

    As for any new shock or diff, the first thing to do is to rebuild them to be sure everything is fine. I used 40wt to start with, now running them with 60wt. Not essential I guess, but using green slime on the seals is a good practice.





    ... I am currently using 4 of them for rear damping ...



    What have you learned today?

    What is the green slime? Same stuff that is used to fix punctures on 1:1 cars (bike tubes etc.)

    So after putting these shocks on my MERV I am not very impressed.

    The damping force seems too low, I changed the fluid to 50 wt and it improved somewhat, however I think a new piston with smaller holes might give me the damping I am looking for. Or I guess I could go to some thicker fluid.

    Any suggestions?

    What springs and oil are you guys running on your GPM shocks?

    So I rebuilt the GPM shocks last night using 80wt. I think it is a pretty good amount of damping for the stock pistion. So far I think the GPM's are a more durable option, however I think the stockers function better. (Smoother)

    Wow guys all I gotta say is that the GPM shocks or any other "upgrade" shocks are better than the stock ones... No more leaks, the GPM shocks increase the ride height and have more responsive bounce. See pics for increased ride height and shocks and my heatsink... Got them all today!

    I don't know what they're technically called but the aluminum GPM one's that I've got have threaded top and bottom "caps" whereas the GTRs I believe are like the stock ones but aluminum. My stocks one's leaked a little bit.

    Yes the GPM shocks are one of your best investment for the MERV

    I've got the traxxas upgraded ones and i think they're overpriced
    these exoteks costs even more so I gotta ask around first
    The black springs are not strong enough for me current setup so I'm looking for a solution

    This will be my first mod... Love the pic above with the 4 setup in the rear.. What adapter do you need to do that?

    Also what do we need to buy with the Shocks.. oil and that green lube? if its just for lubricating, wouldnt the Orange tube silicone you use on cars be fine?

    Bump. Doing a toyZ list tonite. So far it's just these springs and a set of tires. Dirt hawg I think. But what can I buy for good maintenance. Oil, grease etc Anything in general to keep this thing running good

    Got my GPM shocks in the mail from The Toyz today. First purchase from them, quick and reasonable shipping. I'm happy with the shocks and the fact that they come with 3 sets of springs. Looks like they will be a nice upgrade from stock.

    AFAIK the Green Slime on the shock O-rings is to aid in sealing.
    ...that was jacked up!

    I believe the springs are of different stiffness. Black seems to be the softest, gold stiffest and the silver installed.

    If the bottom cap of the stock shocks were threaded they would be usable... But I would personally want a longer stiffer spring maybe from the summit vxl... But I think the GPM shocks were the most useful part I have replaced from stock. I wouldn't enjoy driving the MERV if it weren't for those. Everything else could have virtually stayed stock...

    So what gives the spring such a large resting impact on how high your buggy sits? Is it because there are more threads, so you can preload more?

    Its more how long and stiff the spring is + the preload and shock oil for damping. (well thats what i always thought)

    The stiffer traxxas springs were shorter in length. At the time before the summit vxl came out there was the black springs which were short in length. It would bottom out the MERV on small jumps etc etc. With the stiffer longer gpm springs adding 65wt+ weight oil would help control the bouncing around and would make the shocks more responsive. That would be the damping.
