    Converter and Flexplate Kits

    Kit Includes:
  • 512-GM30 - Hughes Performance TH350/TH400 Pro Street Converter
  • 555-601071 - JEGS 168 Tooth Flexplate Small Block Chevy
  • 070-100-2901 - ARP Flexplate Bolts 7/16'' x .680''

  • JEGS Heavy Duty Flexplates

      Our flexplates are SFI-29-1 approved for drag racing and made in the USA. The .130'' thick plates are manufactured from the highest strength alloy steel that exceeds OEM specifications. Each is die-stamped to ensure an exact fit every time. The ring gear is double welded to prevent separation from the flexplate in high-rpm applications. Final assembly is zinc dichromate plated for a long lasting appearance and to help ward off any degradation from the elements. A final 100% inspection is performed before any flexplate is placed in the packaging to assure total customer satisfaction.

    Hughes Performance Converters

      Pro Street Series - 3000 RPM Stall Converters
      All Pro Street converters are brazed to increase strength and have a full needle bearing design, front and rear to ensure reliability. Not for use in transbrake applications.

      Street/Strip Series - 3500 RPM Stall Converters
      Excellent for weekend racing and high performance street use. All converters are brazed and feature a strengthened sprag, special cut stator, and full needle bearings, front and rear. Not for use in transbrake applications.

      Competition Series - 4000 RPM Stall Converters
      The most important factor in performance is how your car leaves the starting line. The Hughes Competition Series converter is exclusively designed for the serious racer. The replacement of fiber thrust washers with heavy duty needle bearing packs enable this converter to be run on the street, but is recommended for the strip. Not for use in transbrake applications.

      Pro Competition Series - 4500 RPM Stall Converter
      All Pro Competition series converters feature full needle bearing replacement of fiber washers and silicon spot brazing on top and bottom to add strength and reliability. Hughes also installs a premium built sprag assembly and specially machined stator. Not for use in transbrake applications.

      Note: All stall speeds are approximate and will vary depending upon application.

    ARP Flexplate Bolts

      Flexplate and Flywheel bolts play an important role in the performance and safety of race cars and street machines alike. That's why the fastener experts at ARP have developed special bolts that are far superior to OEM hardware. ARP offers two styles of Flywheel/Flexplate bolts: High Performance and Pro Series. They are both forged from aerospace alloy and heat-treated prior to thread rolling and machining. Both feature an exclusive, flat, 12-point head design and larger than stock shank diameter for increased strength and improved flywheel register. The popular High Performance Series is rated at 170,000 psi, and the premium grade Pro Series, originally developed for NASCAR Winston Cup competition, has a 190,000 psi rating. Complete with washers (and nuts where applicable).

    JEGS Easy Kits are designed by JEGS Professionals to help you get all the performance parts you need.
