I highly suggest picking one of these up. If you want to keep that competitive edge then replace they diving board oem chassis and slap one of these on. It will really help you in suspension setup. The truck will become more predictable and the tunning options become more sensitive and more reactive.
Cant say that it will win races for you..thats up to you,but.. it will help you get there by allowing you to dial the hellfire in more true.
