Shop drivetrain parts for the Subaru WRX STI across the GD, GR/GV and VA generations. This aggregate covers the Impreza-based WRX STI through 2014 and the standalone WRX STI of 2015-2021, all built around the EJ-series turbocharged flat-four — the EJ257 2.5-litre in North American models from 2004 to 2021 — with Symmetrical AWD and a Driver Controlled Center Differential (DCCD) in every modern generation; US-market STIs are 6-speed manual only. You will find clutches, flywheels, differentials, axles, drivetrain mounts here — every part in this collection is fitment-tagged for the Subaru WRX STI across the GD, GR/GV and VA generations, so check your generation and year against the product fitment notes before ordering.
Every drivetrain part in this collection is fitment-tagged for a WRX STI, but applications split by generation across the GD, GR/GV and VA range. All modern generations use DCCD Symmetrical AWD, and US-market cars are 6-speed manual only — that is a US-market statement, not a global one. Confirm your generation and year on the product page before ordering.
The DCCD. DCCD-equipped Symmetrical AWD appears in every modern STI generation and lets the driver adjust the centre-differential torque split, with automatic modes as well — it is the feature that separates STI drivetrain parts from WRX parts, so do not assume WRX drivetrain parts cross over.
