PRODUCT DETAILS
RallySport Direct proudly carries a great selection of quality automotive performance upgrades brought to you by GrimmSpeed.
This is the GrimmSpeed Alternator Cover. This alternator cover has been designed to be a direct replacement for the OEM plastic cover that is visually simple and can easily be overlooked. GrimmSpeed has developed a solution that is visually appealing and will improve the overall engine bay aesthetics.
DETAILS:
- Durable aluminum construction
- DuPont black powder-coated finish
- Laser-cut venting
- Machined aluminum mounts
- Slotted mounting features
- Drive-by cable dimples
NOTE:
- Forester, Legacy, and Outback models will require a purchase of an additional OEM Subaru bracket to ensure fitment
- The bracket that is installed on those vehicles from the factory is not compatible with this alternator cover
- These models will need the bracket part number SUB23791AA002 to complete the installation
WHY WE CARRY THIS
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
