    Aluminum vs RPM vs Stock parts

    Just wondered what the consensus was here on aluminum vs RPM vs Stock replacement parts. I have zero aluminum aftermarket parts on my trucks. If I break something I usually upgrade it with RPM parts i.e: arms, bumpers, nerf bars... My thought process is that rpm is a higher grade of plastic but will give when impacted, and is cheaper.

    That said, I just replaced my front wheel bearings in the slash and when the bearings went they took the blocks with them. I was about to buy RPM blocks and thought twice before buying stock for 5 bucks. What do you all do?

    Rpm in some parts, aluminum on others. Depends on what the job of the part is

    It really depends on you, I've snap rpm parts just as easy as stock, I believe the aluminum for the blocks and the carries is the way to go, tightens up suspension and with stands more abuse than plastic.
    If it cant be broke, I'll break it.

    Depends on the build.

    If It's a basher, all RPM. Make it a big, bendy indestructible thing. Gumby with wheels.

    If it's a racer, you are going to want more aluminum and stock stuff, as it is stiffer and more precise in it's function.

    The Ultimate and Platinum Edition Slash 4x4 trucks have close to the perfect amount of aluminum parts. Add an aluminum motor mount and you are good to go!

    I like RPM as well. Does anyone have RPM C hubs and steering blocks? Do they get damaged when the bearings go bad?

    I do on my 2wds. Never had an issue with a bad bearing messing them up. I'm not sure how that even happens, unless the bearing gets so bad it seizes up and you start spinning it in the hub. I like these RPM parts, but they are flexy...which can be a downfall for steering parts. If you are bashing, perfect, if you are racing or want precise steering without a lot of play you are better of aluminum on these parts. My 2 cents.

    BINGO!!!! I added the traxxas aluminum shock towers, a HR roll bar(ties front and rear together) and a TKR6855 – Big Bone Center Driveshaft and Outdrives .

    Truck is now very tunable with those GTR shocks!

    RPM makes great stuff, if you plan on destroying your arms.....I use them and cant break them

    I just got my first STRC product (slash 4x4 bellcrank) and it seems very high quality but I have yet to see
    Too much power is just enough
