Long established for their Jaguar based heritage, JD Classics are pleased to unveil their newly developed JD Sport five speed gearbox. Designed in house, the gearbox has been refined and perfected through rigorous testing by our skilled technicians.

Engineered with synchromesh and helical cut gears as well as a reinforced aluminium cast casing, the gearbox is equally prepared for performance track driving and rallies as well as everyday road use. Its versatility is further emphasised as the gearbox has been specially designed to be fitted with minimal modification to the extensive Jaguar classic car range; whether it be a performance based racing C-Type or a road ready MKII.

Dimensionally the same size as a 4.2 all synchro Jaguar box, JD’s new innovation is also lighter and the dual mounting options allow the gearbox to be removed without having to remove the bell housing. The close ratio gears enable seamless transition between each gear ensuring engines continually operate within their optimum range of power at all times.

Having already been installed in customer owned XK120s and E-Types, feedback has been positive commenting that the gearbox offers ‘a new quality of driving’ and its capability of handling up to 400 horsepower further highlights it’s on road performance without compromising the car’s historical compliancy.

JD Classics Race Shop Team Principal, Steve Riedling, said: “JD Classics made its reputation in classic Jaguars, and we very successfully campaign and support a number of Jaguar models in historic rallies and classic motorsport. With all the lessons we’ve learned, and the customer feedback we’ve received, we’ve developed the new JD Sport gearbox to be reliable, easy to use and with the performance benefits of a modern gearbox. Most importantly, though, it feels like a period gearbox."

Available in kit form or JD fitted. Please contact for details.
