Description
UPDATE:
First batch is in Production, expected in stock by end of April 2026
Mopar Smallblock Magnum (318) Adapter to ZFHP 8 speed HP70 HP90 Adapts the ZF-HP70 and ZF-HP90 8 speed automatic transmissions or the NAG1 5 speed transmission to the Mopar Magnum Small block engine (318) neutral balanced with a Tone Ring for crank sensor. USCT has licensed the proven design from JVX Racing and now manufactures these transmission adapters in our production facility.
Note: Early ZF8HP transmissions came with a 34mm torque converter snout and require Mopar Crank Adapter Sleeve Part Number
04736483AA
to fit the Small block crankshaft recess. Later ZF8HP transmissions use a 46mm snout and are a direct fit into the crank shaft recess. Measure your torque converter snout. Dust shield shown (Car 04591948AB) is not included but should be installed between the engine and the ZF8HP transmission to maintain correct torque converter clearance. Use the correct dust shield for your transmission - car and truck are different.
Included with the USCT7M2105 Adapter
Zinc Plated Flexplate with welded starter ring gear and tone ring
Zinc Plated Bracket to relocate Crank Sensor (Sensor not included - reuse your OEM sensor) with mounting hardware
ARP 7/16 Crank Shaft attaching bolts
ARP M8 torque converter attaching bolts and washers
3 Thick (.130) and 3 Thin (.070) torque converter attaching shims
3 Shim rivets
Not Included: Dust Shield for your specific ZF8HP transmission, car uses
04591948AB
Optional: Mopar Crank bushing
04736483AA
for 34mm Torque Converter Snout Diameter
