GM LT1/LT4 One-Piece Lightweight Flexplate

Designed for high-RPM GM LT1/LT4 engines, this SFI 29.2 certified 1-piece lightweight 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 6.09 lbs, this lightweight version is built to withstand 12,000+ RPM and by weighing significantly less than a factory unit, it delivers more power to the rear wheels by reducing rotating mass.
