EBsOBXT Posted June 19, 2020 Share Posted June 19, 2020 Hey, so ive been getting conflicting fitment details for OEM timing components. 13028AA240 verified fitment for a 2008 EJ255 13028AA250 not verified fitment but told it will fit. I ordered this timing kit. Heck of a deal with all tensioners and idlers OEM. It comes with a new 30mm STi spec belt with the part # 13028AA250. RallySport says that the AA240 will fit a 2015 STi. But that a AA250 will not fit any WRX/XT. Im baffled, how is one interchangeable but the other isnt? Im confused. Ive reached out to the seller. A reputable Subaru Parts dealer who verified AA250 will fit any EJ255 from 2000 to 2018. But again, Subaru itself, doesnt verify fitment? Any thoughts??? Vehicle is 2008 Outback XT Limited 2.5 MT 2458CC DOHC-Turbo EJ255 Link to comment Share on other sites More sharing options...
Max Capacity Posted June 19, 2020 Share Posted June 19, 2020 (edited) Read the timing belt thread in the DIY section.

apexi Posted June 20, 2020 Share Posted June 20, 2020 Just to double check, 13028AA250 seems to be just a belt, and not a kit with idlers and the tensioner. The same is true for 13028AA240, but I did come across a site that has "13028AA240 KIT" as a whole kit with idlers and such. Link to comment Share on other sites More sharing options...
