The LWS-200 reflects the demand for transaxle solutions to suit very high torque GT and drag-event vehicles. Emerging from the same highly-developed design of the LLS (and Ferrari 458 specification MLS variant), the project involved the design of wider, stronger gears combined with a new pinion shaft design, selector barrel and spacer plate.
The result is the highest torque specification of any gearbox in the standard Hewland range, capable of transferring an engine input torque of up to 935Nm.
Like the LLS, the LWS-200 casing is offered in highest commercial-grade aluminium or magnesium specification, and is fully compatible with Hewland’s Semi-Auto system.
In conjunction with highly developed Powerflow™ differential options, and a sophisticated dog and fast selection mechanism, the LWS offers a large selection of ramp angles, ratios and crownwheel & pinions to ensure that our clients do not have to compromise when it comes to their high performance GT transmission system.
