Torsen LSD for Nissan Micra / March: traction and performance
Improve traction and stability on your Nissan with this Torsen limited‑slip differential (gear‑type LSD with helical gears). Designed for JH3, JHQ and JR5 5‑speed gearboxes, it increases grip and cornering speed while keeping a progressive, easy‑to‑drive character.
Vehicle fitment (applications)
- Nissan Micra 160SR / March 16SR – K12 (3rd generation) – engine HR16DE
- Nissan Micra / March – K13 (4th generation) – engine HR16DE
- Nissan Micra / March – K14 (5th generation) – engine HR09DET
Compatible gearboxes
- JH3 (5‑speed)
- JHQ (5‑speed)
- JR5 (5‑speed)
Gear-type LSD: no plates, progressive
Unlike a plated LSD, this unit has no clutch plates to wear. Torque biasing is smooth and progressive, without harsh lock‑up, helping maintain stable and predictable handling.
Reinforced construction
Made from forged Nickel‑Chromoly steel, with treatments and finishes (such as cryogenic treatment, shot peening and WPC surface treatment) to increase surface hardness, fatigue strength and durability under severe use, including high‑torque turbo engines.
Performance benefits
Compared with an open differential, this LSD improves traction, reduces wheelspin and increases cornering speed. Tests report an average gain of around 1 second per kilometer, depending on setup and discipline.
Recommended use: track & competition
- More effective torque distribution for stronger corner exits
- Reduced wheelspin under hard acceleration
- More stable and predictable behavior in sporty driving
Oil recommendations (important)
- Use OEM gearbox oil or 100% synthetic oil without LSD‑specific additives (those are for plated LSDs).
- Install tip: add a little oil directly into the LSD during installation (the factory anti‑rust coating is not for lubrication).
