    What are spools and why would you use them in place of differential. I just blew my savage xl flux v2 rear differential.

    A spool is a lockout that eliminates the differential action completely, mostly used by Drag Racers and Drifters, I really do not recommend using one in a Savage of any kind, all you going to do is break other things down the line....

    Would the spiral gear be any better?

    Not sure if they are better, more tooth contact is always a good thing, but the Flux V2 XL outta have the BP 29/9 type gears in it from the factory, I would just spring for the BP machined gears and shim them correctly and go from there....
    also be aware landing jumps on power is a sure way to blow up diff gears, strip ring gears and pinions and in general destroy your drivetrain so a good practice is to let off the throttle when landing jumps....

    I think I was from my son driving it. Found a cracked a arm and badly bent dog bone took a hammer to the dog bone to fix put it together and within 2min. The differential was done.

    like jam said get in the habit of getting of the power before landing even if your correcting in the air etc takes a while to pick up but you soon do it automatically etc ;)

    I have spirals in one Savage and haven't found any improvement compared to the bullet proof. Spirals are more difficult to shim because the pinion tries to go into the diff housing during forward and out of the diff housing during reverse. You need to shim both ends of the pinion to control this axial movement.

    I've found that if you use rpm a arms. There is no need for shimming. They're shorter so it holds everything in tighter. If you look at the description on the RPM website they explain this on their website
