Best Clutch For 7 3 Powerstroke: Compare ZF-5 and ZF-6 Kits

#1 · Best Overall

1. South Bend SFDD3250-6

Best for: ZF-6 street dual-disc builds.

Why it ranks #1: Its listed application specifies a 7.3 Powerstroke with ZF-6, and the street dual-disc kit includes a flywheel.

A dampened street dual-disc design paired with an included flywheel gives this South Bend kit a clearly specified role in 1999–2003 7.3 Powerstroke trucks with a ZF-6 six-speed. Its configuration helps shoppers seeking a street-oriented dual-disc replacement identify the intended setup before planning a clutch service.

The listing identifies a dampened street dual-disc clutch and a ZF 6-speed application, which lets owners narrow the choice to the stated transmission and street use rather than assume broad compatibility. The included flywheel means it is supplied as more than a clutch disc alone, a practical consideration when planning the parts and installation workflow. Its stated fit is limited to 1999–2003 Ford 7.3 Powerstroke applications with the ZF-6, so the transmission and model-year boundary matters.

Skip it if you have a 1994–1998 ZF-5 truck; South Bend Clutch 1944-5K lists that earlier application.

Choose this for a 1999–2003 7.3 Powerstroke owner replacing a ZF-6 street clutch who wants a dampened dual-disc kit with flywheel included. Its stated boundary is the ZF-6 application, not the earlier ZF-5.

#2 · Best Stock ZF-6

2. South Bend 1944-6K

• Weight: 5 lb

Best for: Later ZF-6 stock replacement.

Why it ranks #2: This stock-style kit is explicitly listed for the 7.3 Powerstroke ZF-6 and uses a solid flywheel.

A stock clutch designation with a solid flywheel makes the South Bend 1944-6K a clearly identified replacement option for 1999–2003 Ford 7.3 Powerstroke trucks with a ZF-6. Its specific later model-year and gearbox pairing helps separate it from the brand’s earlier ZF-5 kits.

South Bend identifies the 1944-6K as a stock clutch kit for 1999–2003 Ford 7.3 Powerstroke applications using the ZF-6, with a solid flywheel specified in the title. That pairing gives owners a focused replacement option and makes the intended transmission clear during parts planning. The stated range is limited to the later ZF-6 application; the listing does not describe an organic material or a performance rating, so those characteristics should not be presumed.

Skip it if you have a 1994–1998 ZF-5 truck; South Bend Clutch 1944-5K lists that earlier application.

This fits the stated need for a stock-style clutch kit and solid flywheel on a 1999–2003 7.3 Powerstroke ZF-6 truck. Owners of the earlier ZF-5 models need a different listed application.

#3 · Best Paddle Disc

3. South Bend 1939CB

Best for: Carbotic four-paddle ZF-6.

Why it ranks #3: The listing specifies a ZF-6 application and carbotic friction with a four-paddle Spicer clutch.

Carbotic friction with a four-paddle configuration makes the South Bend 1939CB a distinct clutch choice for 1999–2003 Ford 7.3 Powerstroke trucks using a ZF-6. The Spicer designation further identifies the listed setup, helping buyers distinguish it from stock and organic clutch options.

The product description specifies Carbotic friction, a four-paddle clutch, and a Spicer configuration for 1999–2003 Ford 7.3 Powerstroke ZF-6 applications. Those named characteristics give shoppers concrete configuration details to compare when selecting a clutch, and the explicit six-speed family application helps avoid treating it as a universal 7.3 fit. The listing does not state a flywheel inclusion or a power rating, so neither should be assumed when planning the installation.

Skip it if you need a listed flywheel; South Bend Clutch SFDD3250-6 specifies one with its ZF-6 kit.

Consider this for a 1999–2003 7.3 Powerstroke ZF-6 owner seeking the stated Carbotic four-paddle Spicer configuration. The listing identifies the clutch setup but does not state that a flywheel is included.

#4 · 375HP ZF-5

4. South Bend 1944-5OK

• Weight: 118 lb

Best for: Earlier 375HP ZF-5 setup.

Why it ranks #4: This organic clutch kit names the ZF-5 application, includes a flywheel, and is described as a 375HP performance clutch.

A stated 375HP performance rating paired with an organic clutch and solid mass flywheel distinguishes this South Bend kit for 1994–1998 Ford 7.3L Powerstroke trucks with a ZF-5. The exact transmission and year range help narrow the fit, while the organic material identifies its specified clutch type.

South Bend lists an organic clutch kit with a solid mass flywheel and a 375HP performance rating for 1994–1998 7.3L Powerstroke applications using the ZF-5 transmission. The flywheel inclusion makes the package relevant to buyers planning a complete clutch-service parts list, while the rating gives a stated performance reference. Its year and gearbox limits are specific, so owners of later ZF-6 trucks should select an application expressly listed for those vehicles.

Skip it if you have a 1999–2003 ZF-6 truck; South Bend Clutch 1944-6K lists that later application.

A relevant choice for a 1994–1998 7.3L Powerstroke owner with a ZF-5 seeking an organic clutch, solid mass flywheel, and stated 375HP rating. Its fit does not extend to the listed later ZF-6 range.

#5

5. South Bend 1944-5K

Best for: Earlier ZF-5 stock replacement.

Why it ranks #5: Its stock-replacement kit specifically fits the 7.3 Powerstroke with a ZF-5 transmission and includes a flywheel.

A stock-replacement designation with a solid flywheel makes the South Bend 1944-5K a specifically identified option for 1994–1998 Ford 7.3 Powerstroke trucks using a ZF-5 transmission. That year-and-transmission pairing helps owners distinguish this kit from later ZF-6 applications when planning a replacement.

South Bend lists this as a replacement clutch kit with flywheel for 1994–1998 7.3L Powerstroke trucks equipped with a ZF-5 transmission. The stock designation and solid-flywheel description clarify the intended replacement style, while the explicit transmission and year range help narrow application decisions. The fit information is focused on those earlier Ford trucks, so owners of 1999–2003 ZF-6 models should look to a separately listed application rather than assume interchangeability.

Skip it if you own a 1999–2003 ZF-6 truck; South Bend Clutch 1944-6K lists that later transmission application.

This suits an owner of a 1994–1998 7.3 Powerstroke with a ZF-5 seeking a stock replacement kit and solid flywheel. Keep the year and transmission boundary in view; it is not the listed later ZF-6 option.

#6

6. ClutchMax CMPRO Stage 4

• Weight: 94 lb

Best for: Stage 4 six-speed applications.

Why it ranks #6: The Stage 4 kit lists a 7.3 diesel with a six-speed for multiple Super Duty models and includes a flywheel.

A Stage 4 clutch kit supplied with a flywheel is the defining package for this ClutchMax offering, listed for 1999–2003 7.3L Turbo Diesel Super Duty applications with a six-speed. The fit list extends through F-450 and F-550, while the supplied application details stop short of naming F-650 or F-750.

ClutchMax identifies this as a Stage 4 clutch kit and flywheel for 1999–2003 7.3L Turbo Diesel applications with a six-speed. The listed F-250, F-350, F-450, and F-550 models give owners a concrete vehicle range, and the included flywheel is relevant when assembling the parts needed for a clutch replacement. Although the title mentions F-650 and F-750, the supplied vehicle-application details enumerate only F-250 through F-550, so the application information is not equally detailed across the title range.

Skip it if you have a 1994–1998 ZF-5 truck; South Bend Clutch 1944-5K lists that earlier fit.

Choose this for a 1999–2003 7.3L Turbo Diesel owner seeking a Stage 4 kit and flywheel for a listed six-speed Super Duty. Detailed fitment names F-250 through F-550, so note that boundary.

#7

7. EFT Stage 1

• Weight: 44 lb

Best for: Streetable factory-replacement upgrade.

Why it ranks #7: The listing specifies 7.3 Powerstroke Super Duty fitment and describes a heavy-duty, streetable, direct factory replacement setup.

A Stage 1 heavy-duty setup described as streetable and a direct factory replacement gives this EFORTISSIMO kit a defined upgrade role for 1999–2003 Super Duty 7.3L Powerstroke trucks. The no-modification statement helps frame installation expectations, while the listing names F-250 through F-550 applications.

EFORTISSIMO describes the Stage 1 kit as a heavy-duty, streetable performance upgrade and as direct factory-replacement parts requiring no modifications. Those details give buyers a practical distinction between an upgrade-oriented setup and a more extensive conversion. The stated vehicle range covers 1999–2003 F-250, F-350, F-450, and F-550 7.3L Powerstroke models. The listing does not specify a transmission, so owners should treat the named vehicle fit as the available application information rather than presume a particular gearbox.

Skip it if you require an explicitly listed ZF-6 application; South Bend Clutch SFDD3250-6 names that transmission.

A fit for owners of the named 1999–2003 Super Duty 7.3L models seeking a streetable Stage 1 heavy-duty replacement without modifications. The listing names no transmission, so that remains a key application boundary.

#8

8. EFT Stage 3

Best for: Stage 3 Super Duty option.

Why it ranks #8: This Stage 3 kit names the 7.3 Powerstroke and compatible Super Duty models, but provides no transmission detail.

The Stage 3 label is the central differentiator of this EFORTISSIMO Racing clutch kit, which is listed for 1999–2003 Ford F-250 through F-550 trucks with a 7.3L Turbo Diesel. Included installation hardware gives the buyer a stated component for the service workflow, while the listing leaves transmission details unspecified.

The title names a Stage 3 kit and identifies Ford F-250, F-350, F-450, and F-550 1999–2003 7.3L Turbo Diesel applications. That vehicle range helps owners of those Super Duty models assess whether the product belongs on their shortlist. Installation hardware is listed among the included components, providing hardware for the installation process. Because the supplied details do not specify a transmission or flywheel, those particulars cannot be inferred from the Stage 3 label.

Skip it if you need a stated six-speed fit; South Bend Clutch SFDD3250-6 explicitly lists a ZF-6 application.

Consider this for a 1999–2003 F-250, F-350, F-450, or F-550 7.3L Turbo Diesel owner comparing Stage 3 options. The supplied information identifies installation hardware but does not name a transmission fit.

#9

9. A-Premium Clutch Kit

• Weight: 42.9 lb

Best for: Broad 1999–2003 Super Duty fit.

Why it ranks #9: Its fitment lists 7.3 diesel Super Duty models, but the supplied details do not identify a transmission type or flywheel.

A-Premium explicitly lists 1999–2003 F-250, F-350, F-450, and F-550 Super Duty trucks with the 7.3L diesel, making its broad named model range the clearest buying cue. The clutch-kit format and reference numbers offer additional identifiers for shoppers comparing replacement components.

The vehicle-fit list spans four Ford Super Duty models for 1999–2003 with the V8 7.3L diesel, helping owners match the product to a specifically named truck. A-Premium also supplies reference numbers, which can support parts comparison during the selection process. The listing calls it a transmission clutch kit but does not name a gearbox or describe a flywheel, so those details should not be assumed from the model coverage alone.

Skip it if you need a stated ZF-6 fit; South Bend Clutch 1944-6K explicitly lists that transmission application.

This is for owners comparing clutch kits for the listed 1999–2003 7.3L F-250, F-350, F-450, or F-550. Its model coverage is clear, but the supplied details do not identify a transmission.

#10

10. AngyMeck Clutch Kit

Best for: Manual-clutch broad truck range.

Why it ranks #10: It lists 7.3 diesel fitment across Super Duty models, but gives no transmission specification or included flywheel detail.

A manual-transmission clutch kit listing that spans 1999–2003 F-250 through F-550 and 2000–2003 F-650 and F-750 gives AngyMeck an unusually broad stated truck range. Its 7.3L turbo-diesel fit information helps owners identify the intended applications before considering the listed replacement references.

AngyMeck lists 1999–2003 F-250, F-350, F-450, and F-550 Super Duty trucks with a 7.3L turbo diesel, plus 2000–2003 F-650 and F-750 applications. The manual-transmission designation helps define the intended drivetrain, while the included clutch kit and replacement OEM numbers support component identification. The listed package is one clutch kit; the supplied details do not describe a flywheel, so buyers should not treat one as an included component.

Skip it if you need a kit explicitly listed with a flywheel; South Bend Clutch 1944-5OK includes one.

This suits manual-transmission owners whose 7.3L Ford truck falls within the listed F-250–F-750 year ranges. The product details identify a clutch kit and references, but do not specify a flywheel.
