Product Overview
KAAZ 1.5-Way LSD DBT1621 – Toyota Performance Limited Slip Differential
The KAAZ 1.5 Way LSD DBT1621 is a performance limited-slip differential engineered to improve traction, acceleration and cornering control in selected Toyota vehicles. Featuring an eight-plate mechanical clutch design, this 1.5-way differential delivers strong locking under acceleration and reduced locking during deceleration.
Designed for selected Toyota Starlet GT Turbo, Corolla Levin, Sprinter Trueno, Toyota Vitz RS and Yaris RS applications, the KAAZ DBT1621 is a performance drivetrain upgrade for drivers seeking improved traction and more predictable power delivery.
Why Choose the KAAZ 1.5-Way LSD DBT1621?
Improved Traction During Acceleration
The KAAZ 1.5-Way LSD helps distribute drive torque between the driven wheels, reducing excessive single-wheel spin when accelerating out of corners. This can improve traction and make power delivery more consistent.
Enhanced Cornering Performance
Unlike a conventional differential, this KAAZ limited-slip differential uses a multi-plate clutch design to generate locking action when required. The result is improved traction during enthusiastic cornering and acceleration.
1.5-Way Differential Operation
The 1.5-way configuration provides strong locking characteristics under acceleration and reduced locking during deceleration. This helps deliver a balance between corner-exit traction and controlled handling when entering corners.
Eight-Plate Clutch Construction
The DBT1621 features an eight-plate clutch arrangement engineered for responsive engagement and mild-to-medium power applications.
Built for Performance and Motorsport
KAAZ differentials are developed for demanding driving conditions, making them a popular choice for modified Japanese performance cars and circuit builds.

Frequently Asked Questions
What does a KAAZ 1.5-way LSD do?
A 1.5-way limited-slip differential provides strong locking action during acceleration and reduced locking action during deceleration. This helps improve traction while maintaining more controlled corner-entry characteristics than an aggressively locking 2-way setup.
Does KAAZ DBT1621 fit the Toyota Starlet EP82 and EP91?
Yes. KAAZ lists DBT1621 for selected Toyota Starlet EP82 and EP91 GT Turbo applications equipped with the 4E-FTE engine.
Does DBT1621 fit the Toyota Corolla Levin AE111?
Yes. Selected AE111 BZ-G and BZ-R applications are listed by KAAZ. Confirm the exact vehicle configuration before ordering.
Is the KAAZ DBT1621 suitable for everyday road use?
It can be used on suitable road vehicles, but the standard clutch-type design may produce more noise and more noticeable locking action than a factory differential. Drivers should consider their intended use and driving preferences.
Can I install the KAAZ differential myself?
Professional installation is recommended. Correct assembly, clearances, lubricant selection and initial setup are important for differential performance and service life.
