UL-Trac Helical Gear-Bias LSD

Ultimate traction, ultimate performance, ultimate versatility - the UL-Trac Helical Gear-Bias LSD unit benefits from long term development on important areas like the gear design and tooth profiles, enable maximum surface contact and in turn fully harness the power that requires delivering. This means the UL-Trac can generate the ultimate traction from any torque biasing gear pack: aided by heavy duty springs to reduce wear and maintain pre-load.
The torque-biasing principle uses internal worm gears to progressively transfer drive from one side of the car to the other if there is a loss in traction at one wheel. It does this almost without feeling through the steering wheel - especially beneficial on front wheel drive cars, or all wheel drive cars at the front. Anyone who has driven a front wheel drive car with a clutch plate, or viscous diff, will understand just what a difference the torque biasing design makes. Not only to the feel and comfort but also to the track times, or just pure handling improvement that it delivers over a stock 'open' differential.
