Supa BEAST and CBEAST Backing Plate Swap by Mike Phillips
The Supa Beast and the CBEAST will ship with a 4 7/8" backing plate. Let's just call it a 5" backing plate. There is an optional 5 3/4" backing plate, let's just call it a 6" backing plate.
Because of the power this tool provides, for my time I'm upgrading to the larger backing plate so I can turn and churn larger pads. Larger pads mean a bigger footprint and that's what I want when tackling any car and especially large vehicles. It's all about speed, the amount of time needed to go from start to finish WHILE maintaining pro-quality results.
I just swapped backing plates, here's some pictures to tell the story.
Here I've removed the factory backing plate.
Here's the part number for the 6" backing plate.
Allow me to point out the new features that lock the backing plate into the rotating shroud for a positive lock-up.
The new design has these tabs formed into the backing plate.
These tabs LOCK into matching slots on the rotating shroud. What this does is it takes ALL the pressure off the 3 bolts that hold the backing plate to the rotating shroud. No stress on the bolts. You get a solid, locked-up attachment of backing plate to rotating shroud.
Tighten down bolts.
Ready to PLOW PAINT!
The Supa BEAST!
Lots of plowing to do....
