MZ helical 1-way LSD for the late S14 Silvia/240SX turbo with shaft fitment. Locks the rear under acceleration while staying neutral under engine braking — the classic street-and-track balance that makes the S14 drive cleanly on a roundtrip and quickly on a track layout.
Start here if you're not sure whether you want 1.5 or 2-way; the 1-way helical is the most forgiving option on a street-driven car.
