Every ZF 8HP Variant Compared: Torque Ratings, Generations and Factory Applications
The ZF 8HP family runs from the 300 Nm 8HP30 to the 1000 Nm 8HP100 across four generations, and the number on the case does not tell you the whole story. This page is the full reference: every 8HP variant, its published maximum input torque for petrol and diesel factory applications, the generation it belongs to, and the vehicles it was originally fitted to.
One thing to be clear about before the table. Every torque figure below is ZF's published maximum input torque for the factory applications that variant was released in. It is a published rating for a standard production car, not a measured failure point and not a modified-vehicle rating. A gearbox that was rated at 700 Nm in a factory BMW or Ram is still a 700 Nm rated gearbox in your project, and what it will tolerate behind a built engine depends on how it is controlled, cooled and driven.
How ZF numbers the 8HP
The naming is systematic. "8" is the number of forward gears, "H" stands for hydraulic torque converter, and "P" stands for planetary gearsets. The number after "8HP" tracks the torque class the variant was designed around and broadly corresponds to its published maximum input torque in newton metres. Stellantis builds the same family under licence and sells it as Torqueflite 8, which is where the 845RE, 850RE and 880RE names come from.
ZF's own data also carries generation suffixes. Where a gearbox appears as 8HP30/I, 8HP30/II and 8HP30/III, the Roman numeral marks which generation that part number belongs to, and that matters when you are buying a used case, because the internals and ratios changed even though the name did not.
The complete ZF 8HP variant table

The table above is the whole passenger-car family. Two smaller groups sit alongside it, and it helps to know they exist so you do not mistake them for something you can buy: ZF's racing version, the 8P 45R, covers a spread from 450 Nm to 1050 Nm and was released in 2016, and the commercial-vehicle 8AP family from 2017 runs from the 8AP 600 T and 800 T at 600 to 800 Nm up to the 8AP 1000 T, 1200 T and 8AP 1200 S at 1000 to 1200 Nm. There is also a row in ZF's own application data for an unnamed 8HP with torque listed as TBD, fitted to the Aebi MT750, Great Wall Pao from 2019 and Great Wall Tank 300 from 2020.
The four generations, and why the generation matters more than the number
Each generation of 8HP uses a different gearset family, and the ratios are the practical difference you will feel.
| Gearset family | Variants that share it | 1st gear | 8th gear |
|---|---|---|---|
| Pilot 8HP70 (2008) | 8HP70 pilot series | 4.696 | 0.667 |
| 1st generation | 8HP30/I, 8HP45, 8HP55, 8HP65, 8HP70, 8HP75/I, 8HP90 | 4.714 | 0.667 |
| 2nd generation | 8HP30/II, 8HP50, 8HP75/II, 8HP76/I, 8HP95, 8HP100 | 5.000 | 0.640 |
| 3rd generation | 8HP30/III, 8HP51 | 5.250 | 0.640 |
| 3rd and 4th generation | 8HP76/II, 8HP80 | 5.500 | 0.640 |
Read that as a torque-versus-spread trade. The first generation set used a 4.714 first gear and a 0.667 top gear. From the second generation onward ZF went deeper on first gear, to 5.000, then 5.250 in the 8HP51 and 5.500 in the 8HP76/II and 8HP80, while pulling top gear down to 0.640 for better highway economy. Choosing between a 1st generation 8HP70 and a 2nd generation 8HP75 is therefore a real decision: same nominal torque class, but the 8HP75 pulls harder in first and cruises at lower rpm in eighth. That difference is invisible if you only compare published torque figures. The pilot series 8HP70 from the 2008 BMW 7 Series is worth calling out separately, because its ratios differ slightly again (4.696 first gear rather than 4.714).
The Torqueflite versions
Three Torqueflite versions appear in ZF's application data, and they map onto the ZF parent variants:
| Torqueflite version | ZF parent | Max input torque (petrol / diesel) | Generation |
|---|---|---|---|
| 845RE | 8HP45 | 450 Nm / 500 Nm | 1st generation |
| 850RE | 8HP50 | 500 Nm / 500 Nm | 2nd generation |
| 880RE | 8HP80 | 800 Nm / 800 Nm | 4th generation |
The 845RE and 850RE are everywhere in Chrysler, Dodge, Jeep and Ram product because they were used behind the 3.6 litre Pentastar V6. The 880RE breaks that pattern: it is a much newer 800 Nm unit whose only listed application is the 2024 Dodge Charger with the 3.0 Hurricane twin turbo straight six.
Which variants are commonly swapped, and why
The swap market does not follow the torque ratings. It follows volume, driveline layout and how easy the case is to control. Four groups dominate.
8HP45 and 8HP50. The defaults for a standard-power build. The 8HP45 sits behind an enormous number of rear-drive BMWs, Jaguars and Land Rovers, and the 8HP50 covers the next BMW generation plus Alfa Romeo, Jaguar and Land Rover again. Both are rated 450 to 500 Nm, both sit at the smaller, lighter end of the family, and both turn up in rear-drive and all-wheel drive donors.
8HP70 and 8HP75. The swap favourites for turbocharged and V8 builds. Both are 700 Nm petrol, the 8HP75 is 740 Nm diesel, and between them they cover nearly every high-output longitudinal vehicle ZF supplied: BMW diesel and V8 models, the whole 5.7 and 6.4 HEMI range, Jeep, Ram, Land Rover, Jaguar, Maserati, Aston Martin and Rolls-Royce. That is why cores are plentiful and why adapter and controller support around these two is the most developed.
8HP76. The 3rd generation 760 Nm unit is the modern target for BMW M cars and the Ineos Grenadier diesel, sitting between the 700 Nm 8HP75 and the 900 Nm 8HP90.
8HP90 and 8HP95. The 900 Nm to 1000 Nm units, popular for high-power builds because the donor list is full of cars that already made serious torque: Hellcat Challenger and Charger, Trackhawk and Durango Hellcat, Audi RS, Bentley, Lamborghini Urus and Rolls-Royce. The trade is size, weight and core cost.
Two groups are swapped less often for good reasons. The 8HP55 and 8HP65 are Audi-only in ZF's application data, so donors are longitudinal all-wheel drive cars, and the TurboLamik manual documents internal wiring differences on those gearboxes between the mechatronic unit and the round connector that do not match the standard BMW 8HP45/50/70/75 arrangement. The 8HP100 is 4th generation, 1000 Nm, and appears only in the BMW XM and the latest M5, so supply is thin.
Two practical points before you buy. If you are comparing the 500 Nm variants specifically, the narrower comparison of the 8HP51, 8HP70 and 8HP76 is covered in 8HP51 vs 8HP70 vs 8HP76: which ZF 8HP should you buy?. And torque rating is only the first filter: the variant has to match your bellhousing adapter, your tunnel, your driveshaft solution and the variant list of the controller running the gearbox. Choose the controller first and the transmission second.
Frequently asked questions
Which 8HP is the strongest? By published rating, the 8HP100 at 1000 Nm for both petrol and diesel. The 8HP90 and 8HP95 are rated at 900 Nm petrol and 1000 Nm diesel, so on diesel applications they are rated as high as the 8HP100.
Is a bigger number always the better swap? No. A higher-rated variant is physically larger, heavier and usually more expensive, and its bellhousing and internal wiring may be less well supported by adapters and controllers. A 700 Nm 8HP70 or 8HP75 is the sensible ceiling for most builds.
What is the difference between a 845RE and an 8HP45? They are the same transmission class. The 845RE is Stellantis' licenced version of the 8HP45, rated at 450 Nm petrol and 500 Nm diesel, and it was built for Chrysler, Dodge, Jeep and Ram applications.
Why does the 8HP75 have two torque figures? Because ZF published separate ratings for petrol and diesel factory applications. The diesel rating is the higher of the two on the 8HP75 (740 Nm against 700 Nm), and it is the same for the 8HP75-LCV used in the Ram 2500 and 3500.
Do all 8HP variants share the same gear ratios? No. There are at least five ratio sets in the family, and first gear ranges from 4.696 in the pilot 8HP70 to 5.500 in the 8HP76/II and 8HP80, with top gear at 0.667 in the first generation and 0.640 from the second generation onward.
Next step
If you are deciding between variants for a specific build, tell us the vehicle, the engine and the controller you intend to run, and we will point you at the 8HP variants that suit that combination. If you already have a gearbox, send us the part number and we can confirm which generation and ratio set you are working with.
Torque ratings, generations and factory application lists in this article are taken from ZF's published 8HP variant and application data. References to gearbox internal wiring, controller compatibility and selector behaviour come from the TurboLamik official manual at manual.turbolamik.eu.
