Replacement Backing Plate For FLEX XC 3401 VRG (4 Inch)

Why Buy This Product?

  • 4 Inch replacement backing plate for FLEX XC 3401 VRG dual action polisher
  • Allows you to use 5" and 5.5" pads, brushes, and other detailing accessories
  • OEM factory replacement for the original backing plate
  • Ratchet and gear tooth design creates a true forced-rotation dual-action orbital movement
  • Smaller diameter accepts standard size buffing pads for expanded usability around any automobile

How It Works

The FLEX XC 3401 is what you get when you combine a dual action polisher with a rotary polisher: a forced-rotation dual action buffer. This unique mechanism spreads out the polishing work, and heat, over a larger area just like a DA polisher. But it uses a ratchet and gear tooth system to turn the backing plate through the orbital spin. This forced motion requires a specialty backing plate to mesh with the machine bell housing. This replacement backing plate comes in a smaller 4” diameter to run buffing pads up to 5.5” in size. Switch out the stock backing plate to polish smaller panels and tighter curves with all your standard buffing pads from your detailing arsenal. The OEM FLEX XC 3401 Backing Plate is the authentic factory replacement part for your 3401 DA Polisher. Only high quality injection-molded plastic, urethane interface surface, and fine hook and loop fasteners can take the vibration, heat, and pure polishing force of the rugged XC3401 machine. Take your XC3401 machine to new places and polish into tighter areas with smaller buffing pads with the 4 Inch Replacement Backing Plate.

Take Your FLEX XC3401 Into Tighter Areas

The FLEX XC 3401 combines the best of both worlds: the power and speedy correction of a rotary polisher with the ease of use and safety of a dual action polisher. Normal rotary machines spin all the power off a single axis, and generate maximum friction and correction power on paintwork. Dual action polishers spin the buffer head off a counterweight to create an eccentric motion, or “throw,” that dissipates heat for a safer buffing job on paint. The FLEX XC 3401 VRG uses a gear and tooth mechanism that ties the rotation and oscillation movements into one powerful motion. This fast-acting machine dissipates heat as it works to safely remove paint without burning the finish, but the direct gear drive transfers more machine power into the workpiece for a deeper and faster paint correction. The FLEX XC3401 ships with a larger 5.5” backing plate that accommodates 6.5” buffing pads and accessories. This extra large backing plate and pad combination is best suited for polishing large flat panels, but is awkward around tighter areas and dramatic curves around modern vehicles. Now with the 4” replacement backing plate, your FLEX XC3401 can fit where smaller, but less-capable machine polishers formerly reigned supreme. Switch out to the 4” XC3401 Backing Plate and take the machine to just about every spot that needs polishing on your car.

Where Can The FLEX XC3401 Work?

With the smaller 4” replacement backing plate, the FLEX XC3401 Polisher fits into tighter areas around any vehicle using smaller standard 5.5” buffing pads. Use the powerful polishing correction power to remove scratches, swirls, and defects from all types of paint finishes, including hard ceramic clear coat finishes, conventional clear coats, single stage paints, and more. Work around bumpers, curved panels, underneath side view mirrors, and spoiler wings without switching to a separate machine with 3” buffing pad. Permanently remove scratches to restore clarity, reflection, and brilliant shine to any painted color finish. Remove scratches and swirls from clear optical plastic for perfect clarity or light transmission on plastic windows, headlights, or tail lights. Choose the FLEX XC 3401 VRG Orbital Polisher for fast correction on any vehicle.

What Machines Is This Backing Plate For?

The 4” FLEX XC 3401 backing plate fits the tooth-and-gear driven design of the FLEX XC 3401 Forced-Rotation Dual Action Polisher.

How To Use:
  • Hold down the black locking button on the top of your FLEX machine to prevent the backing plate from spinning.
  • Once locked, loosen and remove the screw with the included Allen wrench.
  • Lift the backing plate up and away from the gears.
  • Set the new backing plate in, making sure it is properly lined up with the vertical slot in the rotational spindle.
  • Lightly tighten the screw.
  • Push down the black locking clip again and tighten the screw to the final torque.
