Those diffs should work just fine. Make sure you put them in correctly (I have put them in so they both turn opposite directions a couple times!). next thing your truck may need is some better shocks. Yours look like the stock shocks, which work OK, but the caps have a tendency to blow off when landing jumps. Aluminum steering blocks would be a nice addition, especially in the sand. The Integy type II have larger bearings. The sand will eat up your bearings, so the larger bearings may last a bit longer. I am not sure what you have for a steering servo or servo saver, but a nice metal gear, high torque servo and the Pro-line servo saver are also worthy additions. Other than taht, your truck is pretty tight! Definately one of the nicer ones out there, and most likely one of the fastest!
