G&P gearboxes are reinforced from the factory.
Adding Sorbo pads make them all that much better too. The STS is an option but unneeded. I've been running my 380fps v2 G&P for a while now and several times in sub zero weather with zero issues but with a few upgrades. ASCU, new spring, poly nozzle, modify piston and MASK/Sorbo piston and cylinder heads. So, well, yeah a bunch of changes over stock but still no crack.
