JT5 5 Speed Kit for the XK-120 Jaguar

The JT5 XK-120 5 speed kit fits both 3.8L and 4.2L platforms in XK 120 cars. It uses our XK type gearbox. Currently we have no plans to make a bellhousing for this conversion and an adapter plate would push the transmission to far back into the frame therefore we require your bellhousing to be modified for this conversion. By mid spring of 2002 a new designed gearbox will be offered. This transmission in stock form can handle 385 FT Lbs of torque. It is a proven gearbox and is suited for street use and racing where synchros are required. This conversion offers a much improved driveability and shift feel to your car.

Kit includes a new speedometer cable that hooks up to your stock speedometer. The 5 speed gearbox, shifter, knob, driveshaft , clutch disc, and mounting hardware are also included. Customer is required to send us a bellhousing for modification.
