The shocks are GMP alloy adjustable from hong kong at around 40$ . The same for the servos , cause im a cheepskate and i used the extra cash for the crimefighters tires. The shocks work great , youll love em. Now with the mg995 servos i had to use my HPI savage controller cause the steering servo has to be reversed on the controller , the stock one cant do that. You can get a hpi savage controller on ebay really cheep thoue so its not that big of a deal.
