Description:
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.
Meet 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
Works with factory LS starter motor
Notes:
- 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).
- 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.

Product bent just like a few other reviews said. Installed flex plate and starter was hanging. I noticed how wobbly flex plate was when cranking engine over.

It's described as "double welded" Barely welded is more like it. Only welded on one side not both. Save your time and spend a little more to get a real SFI approved flexplate. The welding was horrible the stamping was done on a worn out die. It should have a .400" dish and did not look right. I returned this within an hour of opening it and examining it. Like Ceasar said "Caveat Emptor" At least they took it back. Now I have to wait again for another one.

Made my rear main seal leak as it had a pretty bad wobble after install. Replaced it with a modified gm one and no more wobble. Will not get this one again

Seemed like a great deal. Looked great upon arrival. Stated SFI 29.1 welds however there was not SFI sticker on the unit. Returned ASAP

Flex plate came bent, didn’t realize it until I paid a mechanic to install and on first start up was matching noise, looked up into inspection plate and was bent and could see it wiggling during rotation
