This upgrade replaces factory LOS-3705 and LOS-3674 front and rear drive shafts with a 4140 steel CVD assembly built for LOSI 1/5 5IVE-TE and 5IVE-TG platforms. The shafts measure 152mm from pin center to pin center and include a beefed-up dogbone section to reduce flex under load. The locating pin arrangement from the original parts has been removed to provide a simpler, stronger joint interface.
Fit as direct replacements for the listed LOSI models; verify alignment and driveline angles during installation to avoid binding and check set screw torque in the hubs after the first run. Because the kit can be used for front or rear positions and some builds replace per axle, two packs may be required for a full vehicle refresh.

This 4140 steel CVD set is a direct-fit strengthening option for LOSI 5IVE-TE and 5IVE-TG 1/5 desert trucks where increased drivetrain robustness is required; follow standard fitting checks and run-in procedures after installation.
