The Toyota Supra JZA80 is already a legend—iconic 2JZ power, timeless body lines, and a tuning platform that’s still crushing records decades later. But if you're pushing serious power or taking your Supra beyond casual cruising, then it’s time to talk about one of the most underrated yet essential upgrades: the limited slip differential.
Specifically, the OS Giken SuperLock LSD.
While the factory Torsen unit or open diff might get the job done for mild driving, they simply don’t hold up under aggressive acceleration, cornering, or high-power builds. Whether you're drag racing, drifting, road racing, or just want tighter control on the street, upgrading to an OS Giken LSD for your Toyota Supra transforms how power is delivered to the ground—and it shows.
What Does an LSD Do for the Supra?
A limited slip differential (LSD) manages how torque is distributed between the rear wheels. On a high-performance, rear-wheel-drive car like the JZA80 Supra, this is everything. When one wheel starts to lose traction, a standard open diff sends power to the path of least resistance—usually spinning out the unloaded tire. That’s a recipe for wasted power and zero grip.
An LSD keeps both wheels engaged, giving you maximum traction, better cornering stability, more predictable handling, and sharper throttle response. With a high-output 2JZ under the hood, anything less than a proper LSD is just leaving performance on the table.
Why Choose the OS Giken SuperLock LSD?
The OS Giken SuperLock LSD isn’t your average clutch-type differential. It's engineered to lock under power more progressively and more aggressively than standard units, delivering superior torque distribution under load while staying streetable and quiet when you're off the gas.
This unit features advanced multi-plate design and OS Giken’s proprietary locking system, offering:
-
Near 100% locking capability under throttle
-
Smooth engagement and disengagement for daily driving
-
Long-term durability even under extreme use
-
Rebuildable and tunable for track-specific performance
The SuperLock design means that even under full throttle launches or mid-corner throttle inputs, your Toyota Supra JZA80 stays planted and predictable. No wheel hop. No sketchy breakaways. Just full control, all the time.
This is the same technology trusted by competitive time attack drivers, pro drift teams, and serious street builds—because it works. And it’s not just about laying down power—it's about keeping your build together when it counts.
