HEWLAND ENGINEERING ENHANCES STANDARD PRODUCT RANGE WITH NEW ADDITIONS

Hewland Engineering is enhancing its standard product range with two new additions.  These new product families include the LLS-200 and LWS-200 gearbox and the ED-200 Differential unit, meeting industry demand for high quality ‘off-the-shelf’ solutions.
The LLS-200 gearbox is a six-speed and reverse ‘off-the-shelf’ unit designed for mid or front-engined rear wheel drive sports cars in GT racing. The bigger brother of the LLS-200 is the LWS-200 gearbox, which has been designed for low-revving high torque engines.
The LLS-200 and LWS-200 will replace the NLT gearbox; a unit that has been part of Hewland’s standard product range since the 1990s. As Hewland has continued to innovate and adopt new technologies in its later transmissions, the NLT required an update with the latest design features. The new design can also integrate any features related to a pneumatic paddle-shift system.
The ED-200 differential unit has been designed to mate with in-line gearboxes such as the Hewland IGTC gearbox and for the first time is available to purchase directly from Hewland. This high end diff unit is the answer for most serious rear-drive axle cars.
“We’ve developed these product ranges to meet our clients’ needs for high end technology delivered with speed and precision. It’s a natural complement to our bespoke production capability, which continues to grow from strength to strength,” says William Hewland, president, Hewland Engineering.
