About this item

  • FLEXPLATE: 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.
  • FLYWHEEL BOLTS: Forged from aerospace alloy and heat-treated prior to thread rolling and machining. Fits Chevrolet Gen III/LS Series Small Block. Has a 200,000 psi rating.
  • ADAPTER SLEEVE: This adapter sleeve will connect a GM LS engine crankshaft to an older GM 2/3/4 speed automatic transmission torque converter. It centers the torque converter hub into the LS crankshaft.
  • TORQUE CONVERTER BOLTS: These ARP torque converter bolt kits are for use with GM transmissions like the Chevrolet Powerglide, TH350 & TH400 with a race converter. They also work for 1/2? thick tabs.
  • ENGINE SWAP BRACKETS: Made with OEM specifications for the best possible fitment into your vehicle. These plates will move the crankshaft centerline up .17" in the vehicle. Includes 2 adapter plates, 8 flat head bolts, and 6 flange M10-1.5 bolts (plates are M10 threaded, use the hardware included).
