This GPM aftermarket part is a direct replacement-style front and rear constant velocity drive shaft set designed for LOSI 1/5 5IVE-series desert trucks. Manufacture uses 4140 steel and the pin-to-pin length measures 152mm, matching step-in dimensions for the specified chassis while providing a heavier-duty cross section compared with some factory items.
Key hardware notes from the original data: the set replaces factory part LOS-3705, the dogbone diameter is increased to 8.5mm from the prior 7mm, and the locating pin feature has been removed to improve overall section strength. The pack supplies two CVD shafts intended as front and rear units.
Fitment and tuning role: these shafts are intended for 1/5 scale 4WD desert truck setups where higher torsional load capacity is required, such as when running larger motors, stronger ESC settings, or rough off-road surfaces. Check wheel hex and differential cup engagement during installation to confirm full travel and prevent interference with suspension movement.
If you need a steel replacement set that keeps the original 152mm pin spacing while increasing cross-section thickness and eliminating the locating pin, this GPM set provides those characteristics; confirm compatibility with your hubs and diff cups before final assembly.
