Wheely King suspension

[nzmadforcer]

Hi team, newbie here.

I have a Wheely King and I want to stiffen up the suspension for my Mud Truck project. Can someone point me in the right direction please.

Thanks in advance

They have rather long springs, and other than maybe the nitro king they only had one spring rate. Ebay should still have spare/upgrade parts. You could add some of those spacers, but that would only increase ride height
