OS Giken 1.5-way superlock LSD for Evo 1-10 RS diff. Also fits DSM, Galant VR4, Lancer GSR, Lancer RalliArt, and Eclipse Talon.

These work so well in both street and track applications. The Superlock mechanism ensures quiet operation and optimal grip at all times. A genuine favourite here at Neat Gearboxes.
