GM LT1/LT4 One-Piece Flexplate

Designed for high-RPM GM LT1/LT4 engines, this SFI 29.2 certified 1-piece flexplate is made from 4140 forged steel and features a hobbed-on ring gear and robotic tig-welded converter spacers. Gas nitriding provides for extra surface harness and strength while E-coating offers corrosion protection. CNC-milled pockets and lightening holes reduce the flexplate's rotating mass and rop overall weight. Weighing only 7.6 lbs, it is built to withstand 12,000+ RPM. Weighing significantly less than a factory unit, this flexplate delivers more power to the rear wheels by reducing rotating mass.
