Whether you’re driving the EcoBoost 2.3L Turbo, the mighty 5.0L V8 GT, Mach 1, or the naturally aspirated 5.2L V8 GT350—this L.S.D. is built to deliver authentic performance for every S550/S650 owner seeking true rear-wheel-drive control.
Why L.S.D. for the S550/S650 Mustang?
The biggest leap forward in the 6th generation Mustang lies in its Independent Rear Suspension (IRS). To fully unlock the benefits of this configuration, precise rear wheels control is essential. Installing the Technical Trax L.S.D. transforms your Mustang with:
・Dramatically improved traction
・Sharper cornering performance
・Shorter lap times on track
・Enhanced straight-line stability for street use
・Greater control in drifting scenarios
Features of the TOMEI TECHNICAL TRAX L.S.D.
・Available in 1.5-WAY and 2-WAY configurations
・High initial torque design—ideal for high-powered Mustangs
・Compatible with OEM Torsen L.S.D., and clutch-type L.S.D. setups
・Designed to fit S550 and S650 grades—from EcoBoost to GT350
This is not just a upgraded L.S.D.
Black Colored Forged L.S.D. Case

SPRING DISC
The ultra-compact spring discs were designed to increase clutch capacity while maintaining high initial torque.
VARIABLE RATE SPRING DISC
By utilizing a variable spring rate construction, the spring disc can withstand hard driving and extended use without warping.
HIGH PERFOEMANCE FRICTION DISCS FOR CONSISTENT POWER/TORQUE TRANSFER
The TOMEI L.S.D. utilizes 16 high quality friction disks to ensure that power and torque is transmitted to rear wheels in a smooth manner to allow for precise vehicle control and the ultimate driving experience.
The new and improved Tomei ADVANCE DISC allows for a quieter and more refined driving experience. Unlike other L.S.D.s, the Tomei L.S.D. is offers greater stability during throttle transitions. It eliminates loud clunking noises, making it a highly streetable yet aggressively tuned L.S.D.
1.5WAY / 2WAY
1.5 WAY
The 1.5 way L.S.D. locks up during during acceleration and unlocks during deacceleration. This allows for a more natural feeling under hard braking.
2 WAY
The 2 way L.S.D. locks up on both acceleration and deacceleration. This allows for more precise control of the car using the throttle, which is very beneficial for drifiting.

GEAR OIL INCLUDED
The L.S.D. kit will come with 2 liters of GL-5 80w-90 TOMEI hypoid L.S.D. gear oil. This oil must be used in conjunction with the TOMEI Technical Trax L.S.D. unit. When using the TOMEI Technical Trax L.S.D. with another brand or grade gear oil, the L.S.D. may make a louder chattering sound and increase the wear of the L.S.D. which may result in a decreased life span of the L.S.D. Gear oil with higher viscosity and higher pressure type lubricants may also increase the chattering noise of the L.S.D.
