These shocks really are a 'must do' upgrade on the HBX or SG turning them from being an uncontrolled pogo stick into a car that seems like it has it's wheels full of lead. The quality is excellent despite the plastic body and the O rings look like they will last the test of time. For the price they are a steal.

Good upgrade for SG1601. Springs feel a bit stiffer than the original. Unfortunately I could not yet test the difference, due to the weather.
