I bought a new Jackson DK2m and it comes with 9-42 stock. I just switched them out and put on some 10-52. I also had to add an extra sping in the back and adjust the screws to mkae to bridge float evenly. Should I be worried about the neck now? LIke will I have to loosen the truss road or something? The neck is pretty thin to what I'm used so I'm just being a bit paranoid now lol Don't want it to bow or something!

Also I'm going away for 2 weeks and I'm leaving in 1 hour so I need to know now! lol

It might bow a tiny bit, not enough to harm it. Maybe tighten it just a little bit if you think it needs it. Or just bring an allen wrench with you on the trip.
