Aftermarket X-MAXX Spiral Gear 42T STXM1200FR/G by GPM  [STXM1200FR/G]

Chrome 42-tooth spiral replacement

The STXM1200FR/G is supplied as a single chrome steel replacement gear for TRAXXAS X-MAXX platforms. It carries a 42-tooth spiral profile crafted from high-grade chrome steel and is listed with a hardness value of 50. The unit is intended for installation in either the front or rear spiral positions of the drivetrain.

Only use this gear with the specified spiral counterparts STXM1200F/G1 and STXM1200R/G1; it is not compatible with the stock low-grade steel spur gears or other non-spiral designs. When installed with the correct spiral mates, the chrome steel construction helps limit damage from abrupt braking and supports smoother power transfer.

A straightforward swap for X-MAXX owners running spiral gear setups, the STXM1200FR/G offers a more robust chrome steel option aimed at reducing gear damage while keeping drivetrain feel consistent.
