QBE10J – Honda Civic FK2 / FK8 K20C1 6-Speed Sequential Gearbox — high-quality Quaife product for motorsport and road use.
Honda Civic FK2/FK8 Type R K20C1 6-Speed Sequential Gearbox
The QBE10J is a 6-speed sequential gearkit for the FK2 and FK8 versions of the Honda Civic Type R. 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. It features a replacement Quaife outer gearbox case, compact, drum style sequential gearchange mechanism and an open face dog design ensure a positive gear sequential shift. It also re-uses the original FK2/ FK8 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 gearing.
