Info

This is Garage Sale priced because it has been bolted up and returned.

If you want to bolt a TH350, TH400, Powerglide, and 700R4 transmission up to your LS-Series engine, you need this kit. The spacer properly positions the flexplate and supports the converter hub. For Turbo 350, Turbo 400, and 700R4 transmission application.

SFI 29.1 approved. Dual bolt patterns: stock LS-Series and small GM bolt pattern.

Kit includes:

  • dual bolt pattern SFI rated flexplate
  • flexplate spacer
  • flexplate to crankshaft bolts
  • instructions

Note: Requires a 10-1/2" bolt circle converter. 

Notes

  1. Fits internally balanced Chevy 4.8, 5.3, 5.7, 6.0 LS1/LS6-series V8 engines.
  2. Flexplates are .035" thicker than stock and the starter ring is welded to both sides of the flexplate for additional strength. Constructed from a high tensile strength material these flexplates resist elongation and cracking. All 168 tooth flexplates are sized for stock 3/8" mounting bolts and can be easily drilled for 7/16" diameter high performance torque converter applications and are SFI 29.1 approved.
