This an oversize item that will require freight shipping.

Does not include Transfer case.

QKE8J is a 5-speed sequential gearkit for the EP3 and FN2 versions of the Honda Civic Type R as well as the DC5 Integra / RSX. Ideally suited to circuit racing, drag racing and rally use it’s designed as a direct replacement for the standard six-speed H-pattern Honda transmission.

QKE8J features a replacement Quaife outer gearbox case incorporating an additional support bearing between 4th and 5th gear. A compact, drum style sequential gearchange mechanism and an open face dog design ensure an ultra rapid, positive gear sequential shift.

QKE8J re-uses the original EP3/FN2/DC5 bellhousing half of the transmission casing, enabling the retention of the Honda clutch, differential, driveshafts and mounting points. Wide straight cut (spur) close-ratio gears minimise transmission losses and offer a choice of rally, race or drag race gearing. There is also the choice of a helical set for road and track day applications.

Key technical features of the QKE8J five-speed Honda EP3/FN2/DC5 sequential gearkit include:-

• • Strengthened outer casing and five wider gears
• • Ultra fast sequential gearshift with straight cut or helical close-ratio gears
• • Retains stock EP3/FN2/DC5 clutch, diff, driveshafts and mounts
• • Optional LED digital gear position indicator available
• • Quaife ATB Differential (QDF21U)

PLEASE NOTE: The Quaife QKE8J package includes the new transmission housing, gear lever and cable. Does not include Transfer case.

*Version 2 Update* We are now supplying the QKE8J Version 2 which has been updated with a revised shift mechanism which incorporates the ability to connect a pneumatic shift system directly to the gearbox from factory.
