    Default Pogo Springs - Where to Find Them?

    Hey All,

    I'm looking for a set of pogo seat springs for my shovel. I tried the Colony set but they were too short/light and bottomed out just sitting on them. I've also heard about David Croft who used to make them but no longer does. Third option was aftermarket ones but I keep hearing that they are too light. I'm 205# but I ride with a backpack a lot so add on another 30# so I'm definitely looking for some stiff, heavy duty springs.

    Anyone have an idea where I can find some?

    Haven't been seeing any heavy springs in good condition and all the swap meets are cancelled with this virus runnin around. All this time off to work on the bike and I can't find the parts I need.

    Davestune: Thanks for the reply. That'd be real helpful.

    Dave Croft sold his business to Colony, they should have heavy springs, I will look in there catalog if you want me to.

    Pan,
    I got the "#3082-7 Seat Spring Upper and Lower Set Harley Big Twin 1958-up" and those were the ones that were shorter than stock.

    MontuckyMatt,
    Thanks, but I'm looking for pogo springs.

    Update:

    Thanks to Flatman for telling me about these springs.

    McMaster-Carr Color-Coded Die Springs
    https://www.mcmaster.com/springs/spr...die-springs-6/

    Look at the "For 1" Hole Dia. (For 1/2" Shaft Dia.)

    Flatman recommended 2x5" Gold Heavy (9588K58) and 1x3" Green Extra Heavy (9595K12) for the main Cushion Springs.

    Not sure if the math I did was exactly right but it seemed to check out.

    (1"/Rate)(My seated body weight) = the travel while seated

    I cross checked this with how much it compressed at max load to check what percent I would deflect it. I ended up around 40% with the all Gold Heavy springs and 35% with the Green Extra Heavy springs, so I ordered all Gold (9588K58 and 9588K54) for a little more cushion.

    First problem I had was that the Spacers were too large for the internal diameter of the short cushion spring. Thirty minutes with my neighbor's lathe and I had them shaved down to size. Next problem I had was that the Auxiliary Springs were too soft, so I used the 2.5" Aux and 5" Cushion spring in the upper housing. I may swap them out later.

    After reassembly, I no longer bottom out the pogo just sitting on it. I haven't been able to even on the bumps that used to wreck my spine if I didn't stand up in time.Click image for larger version.
