The SLA1337FR kit contains matched front and rear differentials intended as an aftermarket drivetrain replacement for TRAXXAS 4X4 platforms. Both assemblies are delivered fully assembled with spiral-cut gear sets, CNC 7075-T6 aluminium housings and medium carbon 4140 steel gears engineered for hobby-level durability.
These units are designed for a direct bolt-in installation on the compatible TRAXXAS 1/10 and 1/8 4WD models listed below, eliminating complex gear meshing during fitment. Differential oil is excluded and must be filled during installation to set the desired limited-slip and slipper behaviour.
Install SLA1337FR to renew worn differentials or unify drivetrain parts across your TRAXXAS 4X4 machines, then fine tune oil weight and lash to match track or trail conditions.
