FLEX XC3401 Mini 4.5 inch Backing Plate

Now you can use 5 or 5.5 inch pads with your FLEX XC3401 Dual Action Polisher!

The FLEX XC 3401 VRG Mini Backing Plate is 4.5 inches in diameter and allows you to use 5 or 5.5 inch pads with your FLEX XC3401 polisher. The plate is designed specifically for this polisher, and creates the forced rotation that sets the FLEX apart from other dual action buffers.

The secret to the FLEX XC 3401 VRG Polisher’s professional grade performance is in the backing plate. The unique design forces a true dual action motion, rather than jiggling. The backing plate’s fit and design reduce vibration and give you a smoother, more comfortable motion.

The FLEX XC 3401 VRG Mini Backing Plate is made of durable molded plastic with a urethane pad to dampen vibration and heat. Hook and loop fasteners cover the bottom of the plate from edge to edge. The backing plate is 4.5 inches in diameter. We recommend 5 or 5.5 inch pads. Buff out existing holograms and swirls on black paint finishes with the FLEX XC3401 VRGdual action buffer!

Because of its special features, the FLEX XC 3401 VRG Polisher only accommodates a factory FLEX backing plate. Use a hex wrench to tighten the new plate securely onto the polisher. Add on a foam pad and you’re ready to polish!

The FLEX XC 3401 VRG Mini 4.5 Inch Backing Plate gives you the quality and performance you expect from a genuine FLEX factory part.

OEM fit and performance
I only switched to the smaller backing plate in order to accommodate my arsenal of 5" pads. Expect the extraordinarily good quality and performance as you would from any Flex tool.
ProsFits 5-5.5" pads. Installs on a Flex 3401 VRG flawlessly.
Great product!
It just works, like it's supposed to. Nothing bad to say about it.

Great for smaller 5 inch pads
You need this if you have a flex 3401 and want to use the smaller 5 inch pads. The 6 inch was to big for me to get in certain areas. Extremely easy to switch backing plate back and forth. Easy peasy.
ProsHigh quality FLEX original manufacturer part. Don't get cheap aftermarket it is not the same and may fail.
ConsNo cons this part is 100%

Great Addition to the Flex 3401!
The Flex 3401 comes standard with a 5.5" backing plate that allows you to use 6.5" pads. I took Mike Phillips advice and purchased this 4.5" backing plate that allows you to use 5.5" pads that are easier to use on contoured and curved panels. The 6.5" pads work well on larger vehicles.
ProsSmaller 5.5" pads work well in tighter areas and on smaller cars.
Almost perfect
Factory quality so it works perfectly. I use LC 5.5" flat pads with it and it works very well, but I just wish there wasn't quite so much pad overhang when using the 5.5" pads. Wish this backing plate was about 1/2" wider in diameter and then it'd be a perfect 5*
ProsFlex factory quality so it should last a long time
ConsJust doesn't seem quite wide enough to get the most out of downward pressure while doing correction work.
