The J's Racing 1.5 way clutch type LSD allows for unsurpassed handling improvements on all race applications while also improving your timeslip on the drag strip. The aggressive engagement of a clutch type LSD allows the engine power to be distributed between both front wheels of your Civic. While cornering the LSD throws you around the corner and out with the highest possible speed. While on the straight, the tires hook-up fast and catapult you to a huge improved timeslip. Please note that this item will need to be broken in and must use a specific differential gear oil.
