JL-200
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.

JL-200

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.
