Best Timing Belt Kit For Subaru: Compare 10 Options

#1 · Best Overall

1. Subaru Genuine Turbo Kit

• Weight: 5.96 lb

Best for: Genuine Turbo Idler Set.

Why it ranks #1: The listing names 2002–2014 Subaru turbo applications and includes a genuine belt, idlers and tensioner; it flags a 2002–2003 WRX exception.

This genuine Subaru set identifies its timing belt and individual idlers by component, making it a targeted choice for listed turbo applications. Its OEM-sealed parts suit buyers seeking a Subaru-branded replacement set, with an explicit fitment caveat for certain early WRX models.

The set includes a timing belt, two belt idlers, a cogged idler, another idler, and a tensioner, giving the repairer several named timing components in one purchase. The description specifies 2002–2014 Subaru turbo coverage, but explicitly excludes the 2002–2003 WRX and notes a different idler for those years. That detail matters when planning parts for an early WRX: the stated kit cannot be treated as a universal turbo fit, and the listing does not include a water pump.

Skip it if you need a water pump in the same kit; AISIN TKF-006 (B00CMWCP5M) combines pump and timing-belt service components.

Turbo Subaru owners seeking a genuine belt-and-idler set may find its specified components useful. It is not a pump-inclusive kit, and the 2002–2003 WRX exclusion makes careful application checking particularly important.

#2 · Best SOHC Match

2. Subaru Genuine SOHC Kit

Best for: Non-Turbo SOHC OEM Set.

Why it ranks #2: This genuine set specifies 1999–2005 Forester, Impreza, Outback and Legacy 2.5 SOHC non-turbo fitment, with belt, idlers and tensioner.

The stated 1999–2005 fitment is narrowly aimed at Forester, Impreza, Outback, and Legacy 2.5 SOHC non-turbo models. That precise application makes this genuine Subaru set useful for buyers who want to distinguish the older non-turbo configuration from turbo or later vehicles.

Its listed components include a timing belt, belt idler, cogged idler, another idler, and tensioner, giving a buyer a clearly described set for the specified service. Subaru notes that the cogged idler differs on 2006-and-newer applications, reinforcing why the listed year boundary matters. The description limits this set to 2.5 SOHC non-turbo vehicles, so it is not a general choice for turbo models or every Subaru with a 2.5L engine.

Skip it if you have a turbo Subaru; Subaru’s B01EDIAWS4 lists a genuine timing set for specified turbo applications instead.

Owners of the listed 1999–2005 2.5 SOHC non-turbo vehicles get a clearly bounded Subaru set with named idlers and tensioner. The non-turbo engine and year limits are central to its fit.

#3 · Broadest Listed Fitment

3. A-Premium Subaru Kit

• Weight: 6.42 lb

Best for: Broad H4 Fitment Coverage.

Why it ranks #3: Its fitment list details Subaru model years and 2.0L or 2.5L engines, including turbo applications, plus Saab 9-2X and Baja.

A-Premium spells out an unusually broad set of Subaru H4 applications, including several model years and engine sizes, so buyers can compare listed coverage with their vehicle. The fitment also names Saab 9-2X and Baja applications, making the specification list the key buying aid.

The listing identifies Legacy, WRX, Forester, Impreza, Outback, Saab 9-2X, and Baja applications, with H4 2.0L and 2.5L engines and individual year ranges. That detail gives buyers more to check than a generic Subaru label and helps narrow whether this kit matches a particular vehicle. The supplied kit-parts text is cut off after beginning its contents list, so the available information does not establish all included components or whether a water pump is included.

Skip it if you require confirmed pump and component contents; AISIN TKF-004 (B00HFKEJN2) is explicitly described as a timing-belt kit with water pump.

This can suit buyers whose vehicle appears in its detailed H4 fitment list, especially when comparing year and engine coverage. The incomplete contents description limits planning, so establish what the kit includes before selecting it.

#4 · OE-Matched Water Pump

4. AISIN TKF-006 Kit

• Weight: 10 lb

Best for: OE-Matched Pump-and-Belt Service.

Why it ranks #4: AISIN specifies OE-matched components and a water pump with its belt service kit; the listing names select Subaru Forester, Impreza, Legacy and Outback.

AISIN pairs its timing belt service kit with a water pump, letting owners address both parts during the same labor-intensive service. The brand says the components are OE matched, which gives buyers seeking an equipment-style replacement a coordinated set rather than a belt-only purchase.

Because replacing the water pump and timing components involves about the same work as replacing either alone, AISIN recommends servicing them together; that can avoid reopening the same area for the other part later. The kit’s OE-matched components support a coordinated replacement, while its stated compatibility covers select Forester, Impreza, Legacy, and Outback vehicles. Check the specific vehicle application before ordering, since the listing does not identify every compatible year or engine.

Skip it if you need the listing to spell out year and engine coverage; Subaru’s B01HP5F700 specifies 1999–2005 2.5L SOHC non-turbo applications.

A Subaru owner planning a combined water-pump and timing-belt service may value AISIN’s matched-component approach. Its fitment description is broad rather than year-specific, so confirm the application details against your vehicle before choosing it.

#5

5. AISIN TKF-004 Kit

• Weight: 10.7 lb

Best for: AISIN Pump Kit For Select Models.

Why it ranks #5: This AISIN kit combines a water pump and timing belt with OE-matched components and lists select Subaru Baja, Forester, Impreza, Legacy and Outback.

AISIN’s TKF-004 combines timing-belt service components with a water pump and describes its parts as OE matched. That paired approach suits buyers who want to address the pump during the belt job, while the listed compatibility names select Subaru models and Saab 9-2X.

AISIN says replacing the water pump and timing components involves about the same work as replacing either one, supporting a combined service rather than a later repeat of that labor. Its OE-matched components provide a coordinated kit, and the listing names Baja, Forester, Impreza, Legacy, Outback, and Saab 9-2X coverage. It does not specify compatible years or engines in the supplied text, so the vehicle names alone do not settle fitment for a particular application.

Skip it if you need stated year and engine coverage; Subaru’s B01HP5F700 specifies 1999–2005 2.5L SOHC non-turbo applications.

This suits buyers seeking an OE-matched AISIN pump-and-belt combination for a listed model. Since year and engine details are absent from the supplied description, application verification remains an important boundary.

#6

6. AISIN TKF-001 Kit

• Weight: 7.4 lb

Best for: Compact AISIN Pump Combination.

Why it ranks #6: Its water-pump kit uses OE-matched components and lists select Subaru Forester and Impreza applications, though the supplied listing gives less fitment detail.

AISIN’s TKF-001 pairs a timing-belt kit with a water pump, enabling buyers to plan both components as one service rather than a belt-only repair. Its OE-matched parts are aimed at select Saab 9-2X and Subaru Forester and Impreza applications.

The manufacturer recommends changing the pump and timing components together because the work involved is about the same as replacing either component alone. That combined approach can make a service visit more complete, while OE-matched components provide a coordinated set. The supplied description names select Saab 9-2X, Forester, and Impreza vehicles but gives no year or engine breakdown, so those broad model names are not enough to establish a specific vehicle’s fitment.

Skip it if you need exact Subaru year and engine coverage; Subaru’s B01HP5F700 explicitly identifies 1999–2005 2.5L SOHC non-turbo applications.

This is a reasonable candidate for a buyer planning combined pump and belt service on a listed model. Its broad application wording leaves year and engine fit unresolved, so treat fitment as the key boundary.

#7 · Most Included Seals

7. DWLDMLWC 2.5L Kit

• Weight: 4.03 kg

Best for: Seal-Inclusive Pump Kit.

Why it ranks #7: The listed kit includes a water pump, hydraulic tensioner, bearings, four camshaft seals and crankshaft seal grease, with several Subaru 2.5L applications.

This DWLDMLWC kit adds four camshaft seals and a crankshaft-seal grease to its timing belt, water pump, bearings, and hydraulic tensioner. That broader contents list can help buyers planning a Subaru timing service that includes pump replacement and seal-related work.

The stated package combines a water pump with gasket and seal, tensioner assembly, lower and upper idlers, belt, camshaft seals, and grease. Grouping these parts supports a more comprehensive service workflow and reduces the need to assemble those listed categories separately. Its compatibility text names several 2.5L Subaru applications, including Forester, Impreza, Impreza Sport, and Legacy, but the supplied vehicle list ends mid-entry; verify the complete application before relying on it for a specific vehicle.

Skip it if you need a complete, readable fitment list before buying; AISIN TKF-001 (B008EEYT2E) is also listed for select Subaru applications.

A buyer planning a pump-and-belt service with seals may appreciate the extensive listed contents. Its partial compatibility text is a meaningful limitation, so establish the full application coverage before ordering.

#8

8. IAG Red Racing Kit

• Weight: 6 lb

Best for: Adjustable WRX And STI Setup.

Why it ranks #8: Its red belt, adjustable idlers and billet guide target EJ20 and EJ25 turbo models, including WRX, STI, Legacy GT and Forester XT.

IAG combines adjustable idler pulleys with a billet timing belt guide and red racing belt, offering a more specialized replacement for specified Subaru EJ20 and EJ25 applications. The package targets WRX, STI, Legacy GT, and Forester XT owners seeking those particular timing-system components.

The kit pairs IAG adjustable idlers and a high-strength red racing belt with a billet guide, while retaining an OEM timing belt tensioner. Those named parts make it relevant to a replacement focused on the listed Subaru performance models rather than a general fitment claim. The stated coverage includes WRX 2002–2014, STI 2004–2021, Legacy GT 2005–2012, and Forester XT 2004–2013; the supplied contents do not list a water pump.

Skip it if you need a pump included in the same service kit; A-Premium APTBK759 (B0D8NYM7P1) lists broad H4 model coverage, though its supplied contents are incomplete.

This fits buyers focused on the named WRX, STI, Legacy GT, and Forester XT applications who want adjustable idlers and a billet guide. Its listed coverage is specific, and pump service requires separate planning.

#9

9. Gates TCKWP328DN Kit

• Weight: 9.2 lb

Best for: Complete Pump-Service Kit.

Why it ranks #9: Gates includes a water pump alongside belt, pulleys and tensioners, but the supplied product details do not identify Subaru model-year fitment.

Gates includes a water pump with the belt, pulleys, and tensioners, so a timing-belt job can cover the linked components together. That bundled approach is useful for labor-intensive service, where replacing related parts during the same repair avoids sourcing a separate pump afterward.

The kit combines the same OE components as Gates TCK kits—belts, pulleys, and tensioners—with a water pump. Gates notes that timing-system components wear together and recommends replacing a belt-driven pump when the belt is changed; this one-box combination can simplify parts sourcing for that broader repair. The supplied listing does not name Subaru models or engines, so application-specific fitment needs to be established before purchase rather than inferred from the brand or kit description.

Skip it if you need stated Subaru application details before selecting a kit; Subaru’s B01EDIAWS4 lists turbo models and a specific WRX exception.

This suits a buyer who has verified application fitment and wants a belt, pulleys, tensioners, and pump together. The listing itself gives no Subaru vehicle coverage, so fitment documentation is an essential boundary.

#10

10. Gates TCK304 Kit

• Weight: 5.3 lb

Best for: Component-Sourcing Convenience.

Why it ranks #10: The component kit includes belts, idlers, tensioners, springs, hardware and instructions, but its supplied details do not state Subaru fitment or include a water pump.

Gates’ TCK304 includes belts, idlers, tensioners, springs, supporting hardware, and installation instructions, consolidating many timing-service items in one kit. That package can streamline parts sourcing and provide procedural reference material for buyers handling an application covered by this component kit.

Including idlers, tensioner springs, and supporting hardware alongside belts helps assemble a more complete timing-component repair without sourcing each listed category separately. Gates also supplies detailed installation instructions and technical service bulletins for troublesome applications, which can assist workflow when the relevant bulletin applies. The listing describes broad domestic and import coverage but does not identify a Subaru model or engine for TCK304, and it does not list a water pump among the stated contents.

Skip it if you want a pump included with the belt kit; Gates TCKWP328DN (B07D5W5XBC) explicitly bundles a water pump.

This may suit a repairer who values consolidated timing components, hardware, and written service guidance. Subaru-specific application details are not supplied for TCK304, and its listed contents are not pump-inclusive.
