Speedfreak Racing has produced a tranny insert for your Hyundai Tiburon. This is a Limited Slip Differential conversion kit, which installs into your non-LSD differential converting it into a proven and competitive limited slip differential that enhances your traction needs. In cornering and braking, it functions as a disc-type limited slip. In hard acceleration, the SFR LSD insert works as a locker causing both wheels to receive equal power instead of just one wheel spin.

This will change your poor traction open-style differential into a posi-traction powerhouse. This allows both wheels to put power to the ground evenly, instead of just putting the power to a single wheel.

The SFR LSD insert serves two distinctive functions in your street or race vehicle. First, it functions as a disc-type limited slip in cornering and braking. Steel plates exert pressure against spider gears using spring pressure to regulate the amount of slippage at the wheels. Helping to accelerate earlier, while exiting corners at a higher speed.

Under heavy acceleration the SFR LSD insert works as a locker. The two steel plates pivot, locking spiders, causing both wheels to exert equal power to the pavement. This significantly reduces torque steer. With over 150,000 miles of testing, there has been no significant wear of these plates. Although seemingly simple, this design adds a surprising amounth of traction to your vehicle.

All of our units are assembled with blueprinted matched sets of progressive-rate springs to achieve equal load distribution to the disc plates, which dramatically enhances reliability and performance.

Made with tool-steel. Comparable competitors products are made only with mild steel. Tool-steel is approximately 3 times stronger than mild steel.

This unit comes with a full Lifetime Warranty against manufacturer defects. This warranty is valid for both street and race use.

For 5 speed models only.
