Description

Replace the underperforming factory flex plate on your Dodge Ram diesel with the XDP Tow Series Flex Plate XD646. If your truck is used for constant heavy-duty towing, it's only a matter of time before your factory flex plate fails. Modifications and continuous heavy hauling add further strain to the flex plate which can result in heat spots from the torque converter. These heat cycles can cause these heat spots to crack and cause the center of the flexplate to tear.

This Tow Series Flex Plate is engineered to withstand the abuse of heavy towing and not break the bank. Not only is this flex plate ideal for towing, but the additional strength makes it well-suited for competition, off-road, and other severe-duty conditions. The flexplate is manufactured from cold rolled steel and features a black e-coat finish that helps prevent corrosion. Being SFI 29.1 approved, this will be able to last for many years of competition and heavy-duty use.


Features:
  • SFI 29.1 Certified
  • Robotically Cold-Welded Ring Gear
  • Manufactured From Cold Rolled Steel
  • Black E-Coat Finish Helps Prevent Rust
  • 4mm Thick Centerplate Provides Rigidity
  • Ideal For Heavy-Duty Towing, Competition, & Severe-Duty Requirements
Manufacturer Warranty*:
2 Year / Unlimited Mileage
Note:
152 Teeth
Internal Balance
Some trucks may be equipped with one or two shims or spacers on either side of the OEM flex plate.
These shims or spacers will not be needed for installation of the XDP flex plate as it is thicker than the OEM flex plate.
Removal of any shims or spacers is necessary to ensure good thread engagement of the flex plate bolts to the crankshaft.

Great product
Cory R. (Mississippi) | November 12th, 2025
When my OEM flexplate cracked and had bad teeth, I wanted to upgrade, but didn't want to break the bank either. I found exactly what I needed and wanted the shipment was fast, and the product was great quality. I did the work myself. It fit perfectly, just like it was OEM. I would recommend this flexplate to anyone wanting to have a great upgrade, but don't want to spend hundreds of dollars. This is a great product, great quality, and perfect fit.

Installed this flex plate because my factory one busted, this one fit perfect and 2 days later I towed my fifth wheel camper 1200 miles and the trip was flawless.
