Competition‑Grade Torsen B Mechanical Limited Slip Differential

Engineered specifically for the Losi 5ive‑T 2.0 platform, this next‑generation Torsen B mechanical LSD from Antz Racing delivers faster response, stronger locking performance, and superior stability under extreme driving conditions. Featuring Antz Racing’s proprietary locking structure, it provides a significant performance upgrade over traditional friction‑plate Torsen designs.

Key Features

• Proprietary Antz Racing Locking Structure

Our patented mechanical locking system reacts instantly to traction changes, ensuring precise torque distribution during acceleration, cornering, and drifting.

• Strong, Consistent Locking Performance

Locking force does not rely on friction plates, meaning no performance fade, no heat‑related degradation, and no sensitivity to wear. Long‑term stability is guaranteed.

• Higher Torque Bias Ratio (TBR)

Delivers a wider torque distribution range, allowing more power to be transferred to the wheel with better traction. Improves corner exit speed, acceleration efficiency, and overall vehicle control.

• 3× Enhanced Durability

No friction plates, no thermal decay. The internal structure is designed for long‑term competitive use with significantly reduced maintenance requirements.

• Direct Fit for Losi 5ive‑T 2.0

Fully compatible with the original platform. No modifications required — simply replace the stock differential and enjoy immediate performance gains.

Performance Benefits

Sharper cornering stability with improved outer‑wheel traction
Stronger straight‑line acceleration with reduced wheel slip
More predictable drifting control with stable torque delivery
Better off‑road traction on uneven or low‑grip surfaces
Consistent performance even during long competitive sessions

Ideal For

Racing
Off‑road competition
Drift setups
High‑power engine or brushless conversions
Professional drivers seeking maximum control and stability
