The JL is a modern, technologically advanced 5 speed sequential box, suitable as a replacement to the incredibly popular LD-200. Retro-fitted with minimal chassis or suspension modifications, the JL offers an effective upgrade with minimal setup alterations, boosting performance to meet modern competition.


In utilising the ratios from the well proven FTR range, the JL delivers excellent reliability at a low cost and weight, together with a wide range of off-the-shelf gearing options. To ensure maximum track-time, gear ratios can be changed trackside without the need to remove the transmission from the vehicle.

Centrally mounted 4th and 5th ratios reduce shaft bending, improving component life, whilst a range of differential options are available including the advanced Powerflow™ limited-slip unit. When combined with the optional Hewland Semi-Auto System, the JL provides maximum performance within an affordable budget.

Utilised by the entire USF2000 grid, the JL has proven itself as the ideal transmission for any lightweight single-seater looking for a modern, 5 speed sequential unit.
