Quaife For Ford Rocket In-Line 4-Speed Sequential & Drop Gears

Designed as a replacement for the Ford Rocket gearbox used for oval / short circuit racing, QBM1M provides groundbreaking levels of user configurability in a compact, state-of-the-art package which is rated to transmit up to 250bhp
An open face four dog design, four straight-cut gears and a barrel style shift mechanism offer ultra-fast gearshifts with a choice of gear lever locations, while the lightweight, short design of QBM1M allows rearward positioning of the engine within vehicles that previously used a short tailcase Rocket gearbox
QBM1M’s drop gear mechanism is secured by circlips and is situated beneath a ‘quick change’ cover, enabling users to easily alter the overall gearing

Six drop ratio choices, plus a huge range of 1st to 4th gear ratios means QBM1M users can fine tune gearing to suit circuits or even weather conditions in a matter of minutes.
Key technical features of the QBM1M four-speed sequential Rocket-style gearbox with drop gears:

• Ultra-fast sequential shift with barrel style change mechanism,
• Wide range of base gear ratio sets and six drop gear options,
• Quick change drop gears for easy overall gearing changes,
• Compact design with choice of gear lever locations,Gear Ratios With Base Drop Gear Set, 1st 2nd 3rd 4th
