This 13T pinion and 43T spur transmission gear set is an RC-scale replacement designed to fit the centre gearbox on LOSI LMT solid axle monster trucks. The gears are manufactured from medium carbon steel to match stock dimensions and allow a direct swap when originals show wear or damage.
The kit targets routine drivetrain service and repair rather than high performance tuning. Install to restore correct mesh and backlash in the centre gearbox, and verify spur and pinion bearing fitment before final assembly to avoid premature wear.
