The question is can your OEM suspension be improved to make it work as well as aftermarket suspension. The short answer is, yes and for a lot less money.
Inside your cartridge forks and shock is a piston that the oil is forced to pass through. Long ago, OEM pistons restricted this oil flow because the holes were too small. This is no longer the case. Oil flow is controlled by the shim stack.
The shim stack is a bunch of washers of different thickness and diameter. I change the shim stack to get the damping curve I want.
The color of the piston makes no difference.
