This GPM aftermarket set is presented as a direct-replacement front and rear constant velocity shaft kit designed specifically for LOSI 1/5 5IVE-series desert trucks. Construction uses 4140 steel and the pin-to-pin measurement is 152mm to align with the chassis step-in points while offering a beefier cross section than some original items.
From the provided hardware notes: the set is intended to replace LOS-3705, the dogbone diameter has been raised to 8.5mm from the earlier 7mm, and the locating pin has been removed to strengthen the main section. The kit supplies two CVD shafts for front and rear positions.
Use case and installation advice: these shafts are aimed at 1/5 scale 4WD desert trucks that require increased torsional capacity—common when fitting larger motors or running aggressive ESC profiles. During install confirm there is no interference with wheel hexes or differential cups to ensure full suspension travel.
For owners seeking a steel replacement that keeps the 152mm spacing while increasing section thickness and removing the locating pin, this GPM kit is designed to deliver those traits; double-check hub and diff cup engagement before completing assembly.
