The JR-DT309-GU kit replaces the DT-03's factory plastic servo saver and tie rods with an aluminum hi-torque 25T servo saver and precision aluminum tie rods. This aftermarket upgrade is intended to reduce steering play and deliver a more direct connection between the servo output and the steering knuckles.
Compatibility is limited to DT-03 based assemblies. The servo saver requires a 25T spline interface; verify your servo output or use an appropriate adapter. The aluminum tie rods offer reduced flex and improved repeatability under load.
Installation: remove the original servo saver and tie rods, transfer any bearings or spacers required, and align the aluminum parts to the steering geometry. Check binding through the full steering travel and retighten bolts after the first session. Use JR-DT309-GU to refine steering response rather than to alter suspension characteristics.
