Make your Gen III LS swap a breeze with this flexplate adapter for GM automatic transmission. These platinum series flexplates are engineered to handle extreme duty applications and designed to take the punishment of today's high horsepower Gen III engines. The 4mm thick centerplate provides a solid foundation (that's 0.035" thicker than stock). Ring gears are precision welded to meet SFI 29.1 specifications, utilizing robotic cold-welding processes. These flex plates are inspected throughout the manufacturing cycle to ensure a high quality, safe end product.

  • SFI 29.1 certified
  • Direct bolt on¬†for Gen III LS engines w/ "short" crank flange
  • Adapts to GM TH350/700R4/2004R/4L60/Powerglide transmissions
  • Works with 10.75" & 11.066" (11.1") bolt-pattern torque converters
  • Constructed from cold-rolled premium steel
  • 0.035" thicker than stock flexplates
  • Long lasting gold iridited finish prevents rust
  • Forged 1-piece steel ring gear w/ 168 teeth
  • Features double welded ring gears for added durability
  • Works with factory LS starter motor

For 1997-07 GM LS1/LS6 engines (up to '09 for LS2) and 4.8/5.3/6.0 truck engines including L33, L59, LM4, LM7, LQ4, LQ9, and LR4. Adapts all of these engines to TH350, 700R-4, 200-4R, 4L60 and Powerglide transmissions that originally came behind a non-LS engine (such as a SBC or BBC V8).

Notes

 

  1. If you're installing a TH350, TH400 or 700R4 behind an LS engine, we recommend the use of adapter sleeve 57518346 which centers the torque converter hub into the LS crankshaft. Also, we recommend new flexplate bolts such as 1012442901. 
  2. May not work with some 1999-2000 LQ4 6.0 LS engines, specifically ones that came with a 4L80E automatic as they require a flat flexplate due to the "tall" crank flange.
