UNITRAX equipped this 2004 – 2005 Mazda Miata IRS differential with the revolutionary O.S. Giken Super Lock.
OS Giken utilized its accumulated racing knowledge and engineering experience to develop its own limited slip differential. Four years of extensive research and development lead to a new and revolutionary LSD design with the capacity to house an unprecedented number of friction plates (up to 28 plates in total) and thus the OS Super Lock LSD was born. The increased number of plates directly has not only dramatically improved our LSD design’s locking force and enables it to lock fully and completely. An added benefit to being a fully locking mechanism is that less heat is generated, thus resulting in incredible durability and reliability.
The OS Giken Super Locks are precisely machined from the highest quality materials. Sound engineering and forged gears make the Super Locks the most durable and reliable race performance LSDs available.
The O.S. Giken Super Lock is also available for the Honda S2000
