The OS-250R Gear Oil was specifically formulated to provide maximum performance and smooth comfort for the OS Giken Super Lock LSD. Lots of testing was done to achieve the appropriate formula needed for the LSD to be smooth, be quiet, and endure the rigors of a racing environment.
SAE Rated at 80w-250, it is the top choice by race teams for protection and durability, yet maintains streetlike-driveability.
