Truck platform, not car
This listing is for Dodge/Ram truck-spec 8HP70, 8HP75, 8HP90 and 8HP95 transmissions. Mopar car-platform 8HP units use a different kit, listed separately. The truck output flange is also a different bolt pattern from the car unit, so check the matching driveshaft adapter too.
Converter centering sleeve
The billet flex plate uses an adapter sleeve that drops into the center bore to reduce it, so one kit covers both Dodge converter diameters found across second and third generation transmissions. Remove the sleeve for the larger spud and the same plate handles it.
Two threaded holes accept 8-32 socket head bolts if you want the sleeve positively retained. The sleeve sits on a machined lip that keeps it elevated off the full surface, with three relief points — so if it ever seizes after heat and load cycling, a punch or screwdriver taps it straight back out.
Is the 8HP45 supported?
The older Dodge 8HP45 is not supported. (The Jaguar 8HP45 is a different transmission and is covered by ASE's Jaguar kit.)
You will also need a TCU
This kit is the mechanical adapter only. The 8HP will not shift without a standalone transmission controller, purchased separately.
