The kit includes a billet torque converter flex plate that fully replaces the weak stamped-steel OEM LS\/LT flex plate, a billet engine-to-transmission adapter plate with an integrated dust shield, and a press-fit steel converter pilot adapter.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBillet 6061 Components\u003c\/li\u003e\n\u003cli\u003eBillet Torque Converter Flex Plate\u003c\/li\u003e\n\u003cli\u003eBillet Motor Adapter Plate with Integrated Dust Shield\u003c\/li\u003e\n\u003cli\u003e360° Mounting Surface — Bolts to Factory GM Cast Oil Pan for Added Rigidity\u003c\/li\u003e\n\u003cli\u003eComplete Hardware Kit\u003c\/li\u003e\n\u003cli\u003eDual-Diameter Pilot Spud Adapter (46mm and 34mm Adapters Included)\u003c\/li\u003e\n\u003cli\u003eHardened Steel Starter Ring Gear\u003c\/li\u003e\n\u003cli\u003ePrecision Stainless Dowel Pins for Proper Alignment\u003c\/li\u003e\n\u003cli\u003eAccepts Standard-Length OEM or ARP Manual Transmission Flywheel Bolts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy a Billet Flex Plate\u003c\/h3\u003e\n\u003cp\u003eThe flex plate in this kit is a full replacement for the factory LS\/LT unit — not a converter spacer that leaves the stock stamped plate in service. On a high-torque swap the OEM plate is the weak link long before the transmission is. CNC machined from heat-treated billet 6061-T6 aluminum and engraved.\u003c\/p\u003e\n\u003ch3\u003eConverter Pilot Fitment\u003c\/h3\u003e\n\u003cp\u003eThe steel pilot adapter presses into the factory pilot bearing register in the crankshaft rather than slip-fitting, which keeps the converter concentric to the crank and eliminates the rattle common to loose-fit adapters. Both common ZF converter pilot diameters are covered — 46mm and 34mm adapters are included, so there is no need to identify your converter before ordering.\u003c\/p\u003e\n\u003ch3\u003eEngine Compatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGen 3 LS — 4.8L, 5.3L, 6.0L. \u003cstrong\u003eDoes not fit early long-crank 5.3L and 6.0L engines.\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eGen 4 LS — 4.8L, 5.3L, 6.0L, 6.2L, 7.0L. 8-bolt and 9-bolt crankshaft variants supported by special order.\u003c\/li\u003e\n\u003cli\u003eGen 5 LT — all variants.\u003c\/li\u003e\n\u003cli\u003eGen 5 90° V6 — LV1 and LV3 4.3L direct injected.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTransmission Compatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRam 1500 HEMI 8HP70 — 2012–2019\u003c\/li\u003e\n\u003cli\u003eRam 1500 HEMI 8HP75 — 2020–2024\u003c\/li\u003e\n\u003cli\u003eRam HEMI 8HP75 LCV — 2018–2024\u003c\/li\u003e\n\u003cli\u003eRam TRX 8HP95 — 2020–2024\u003c\/li\u003e\n\u003cli\u003eChrysler 300 5.7L HEMI 8HP70 \/ 8HP75 — 2015–2023\u003c\/li\u003e\n\u003cli\u003eDodge Charger \u0026amp; Challenger 5.7L \/ 6.4L HEMI 8HP70 \/ 8HP75 — 2015–2023\u003c\/li\u003e\n\u003cli\u003eDodge Durango 5.7L \/ 6.4L HEMI 8HP70 \/ 8HP75 — 2015–2023\u003c\/li\u003e\n\u003cli\u003eJeep Grand Cherokee 5.7L \/ 6.4L HEMI 8HP70 \/ 8HP75 — 2015–2023\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBefore You Order\u003c\/h3\u003e\n\u003cp\u003eRunning a used transmission?

Be aware that the car versions of the ZF 8HP do not have a provision for a passenger-side starter, so the bellhousing will need to be trimmed to clear the LS\/LT starter snout. Truck-spec transmissions have the pocket already.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this require modification to my engine or transmission?\u003c\/strong\u003e\u003cbr\u003eThe engine side is a bolt-on. On the transmission side, the Mopar 8HP has starter provisions cast into both sides of the bellhousing. Because the LS platform cannot run a driver-side starter, that casting is unused on this swap — and depending on your header choice, the boss on the driver's side may need to be relieved for clearance. Header designs vary too widely for us to predict this, so plan for the possibility.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to reuse my stock flex plate or pilot bearing?\u003c\/strong\u003e\u003cbr\u003eNo. Both come out and stay out. The billet flex plate in this kit replaces the factory unit entirely, and the pilot adapter takes the place of the pilot bearing or bushing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat flywheel bolts does this use?\u003c\/strong\u003e\u003cbr\u003eStandard-length OEM GM or ARP manual transmission flywheel bolts, 6 or 8 depending on your crank. Bolts are not included — use ARP for anything making real power, torqued to ARP spec with thread locker and ARP lube under the head.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this work with an aftermarket oil pan?\u003c\/strong\u003e\u003cbr\u003eYes. The adapter plate uses all seven fasteners with a factory GM cast oil pan for maximum rigidity, or five fasteners with a fabricated steel pan. Both configurations are supported by the included hardware.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this include the transmission, torque converter, or controller?\u003c\/strong\u003e\u003cbr\u003eNo. This is the mechanical adapter package only — adapter plate, flex plate, pilot adapter, and hardware.
