Torsen Limited-Slip Differential PSA MA – Gear-type LSD 206, 106, AX, Saxo, C2, C1, 205

Torsen LSD PSA MA: traction and performance for motorsport

Optimise traction and stability with this Torsen LSD PSA MA (gear-type limited-slip differential). It is fully compatible with the OEM PSA MA final drive and fits many cars using an MA gearbox: Peugeot 206, 106, 205, Citroën AX, Saxo, C2, C1 (and other MA-compatible models).

Gear-type LSD: clutchless, durable and progressive

Unlike a plate/clutch LSD, this gear-type LSD has no plates or clutches to wear out. Torque transfer is smooth and progressive, without harsh lock-up, for a more stable feel and better drive out of corners.

Forged steel + reinforced treatments

Made from forged Nickel-Chromoly steel, with dedicated strength-focused treatments/finishes (such as super sub-zero, shot peening, WPC) to increase surface hardness, fatigue resistance and durability in harsh conditions.

Performance gains

Compared with an open differential, this type of LSD significantly improves traction, reduces wheelspin and increases cornering speed. Tests report an average gain of around 1 second per kilometre, depending on setup and discipline.

Recommended use: Track & Motorsport

• More effective torque distribution for stronger acceleration out of corners
• Reduced wheelspin under power
• More predictable behaviour in demanding conditions

Oil recommendations (important)

• Use an OEM gearbox oil or a 100% synthetic oil without LS additives (LS oils are for plate/clutch LSDs).
• Install tip: add a little oil directly into the LSD during installation (the factory anti-rust oil is not meant for lubrication).
