Shop drivetrain parts for the Subaru Legacy 2.5GT and 2.5GT spec.B 2005–2012 (BL/BP and BM chassis). The core is the fourth-generation BL sedan and BP wagon (2005–2009, US wagon 2005–2007) plus the fifth-generation BM 2.5GT (2010–2012), all Symmetrical all-wheel drive with the 2.5 L EJ255 DOHC turbo flat-four. The spec.B adds drivetrain hardware over the standard GT on top of the shared Symmetrical all-wheel drive. You will find clutches, flywheels, differentials, axles, drivetrain mounts here — every part in this collection is fitment-tagged for the Subaru Legacy 2.5GT and 2.5GT spec.B 2005–2012 (BL/BP and BM chassis), so check your trim, year and engine against the product fitment notes before ordering.

Frequently Asked Questions

What drivetrain parts fit my Subaru Legacy 2.5GT and 2.5GT spec.B 2005–2012 (BL/BP and BM chassis)?
Every part in this collection is fitment-tagged for the Legacy 2.5GT or spec.B, but fitment splits by generation, body and trim: BL/BP cars run 2005–2009, the BM 2.5GT runs 2010–2012, the US spec.B is sedan-only, and transmissions range from 5-speed manual and 5-speed automatic on the GT to a 6-speed manual on later spec.B and BM GT cars. Confirm your chassis, year and trim on the product page before ordering.

What does the spec.B add over a Legacy GT in the drivetrain?
A rear Torsen limited-slip differential is part of the sourced spec.B package, on top of the standard Symmetrical all-wheel drive shared with the GT. The spec.B also moved from a 5-speed manual in 2006 to a 6-speed manual from 2007, so match drivetrain parts to trim and year.
