MUZZOOM MMS INSPIRED 4WD REAR DRUM DIFF CONVERSION
For the Schumacher CAT SWB/XL/XLS (original and re-release) and Procat.
Developed together with James Hodgson, this kit enables the standard kit rear integrator to be converted to a drum diff based on the popular period hop-up diff by MMS. Similarly, it can be used to convert a standard kit Procat 3-piece rear diff.
This conversion enables you to upgrade your drivetrain while retaining the period standard belts and is intended as a more authentic upgrade for vintage racing.
Note that when converting an integrator to a drum diff, you will also need to replace the standard kit layshaft diff to a conventional pulley arrangement. We recommend using the Muzzoom KF2 Slipper Conversion - 4wd.
Note that this is a conversion kit which re-uses the following parts from the original standard kit:
- Integrator/Diff axle
- Thrust bearing and disc springs
- Driveshaft outdrives
- Driveshaft bearings
- Belts
