3D printed replacement Team Associated RC10 RPM style wide rear arms. These are the same geometry as the RPM 70542 arms for use with the Stealth gearbox. The arm mounts need to be moved inboard and use a bespoke RPM arm mount, which will be available separately. You can see the difference in the photos with an original gold pan chassis and a 'slightly used' black chassis modded for the RPM arms. You do not need to use longer driveshafts as the distance from the diff to the rear upright remains the same.

The hingepin holes have been hand reamed.
