GEARBOX UPGRADES

QUAIFE GEARBOX UPGRADES- WHAT IS THE REQUIREMENT?

Improving any car's performance isn't purely a quest for outright reliability, as it will also give significant performance benefits.  Ask any race or rally team and it will view a transmission upgrade on the same level of importance as engine performance or the latest trick damper design.

GEARING AND PERFORMANCE

Standard factory gearing is a compromise betwen fuel economy, top speed, noise and comfort. But in the world of motorsport, performance rules, and factors like noise and fuel economy become less important. It is this performance that QUAIFE exploits with its transmission upgrades.

Generally, rally, race and rally disciplines require lower gearing than any manufacturer provides, to maximise acceleration and perforance whether on the circuit or rally stage. This is why QUAIFE offers a number of options for race, rally and rallycross applications. The options include:

QUAIFE helical, close-ratio, synchromesh gear kit
• Helical cut gears to minimise noise
• Closer gear ratios to maximise engine performance- ideal for highly tuned engines with narrower power bands
• Wider gears to improve durability
• Frequently uses standard final drive to reduce costs
• Standard factory synchromesh engagement for smooth selection.

QUAIFE semi-helical close-ratio synchromesh gear kit with lower final drive ratio
• Helix designed to reduce transmission power losses
• Helical cut gears to minimise noise
• Closer  gear ratios to maximise engine performance- ideal for highly tuned engines with narrower power bands
• Often features taller first gear for race and rally applications
• Wider gears to improve durability
• Several lower final drive options to optimise overall gearing for race, rally or rallycross use
• Standarard factory synchromesh engagement for smooth selection.

QUAIFE straight cut close-ratio synchromesh gear kit, revised final drive ratio
• Straight cut or ‘spur' gears to greatly reduce transmission power losses
• Closer gear ratios to maximise engine performance - ideal for highly tuned engines with narrower power bands
• Often features taller first gear for race and rally applications
• Some kits upgrade from 5 to 6-speeds
• Wider gears to improve durability
• Several lower final drive options to optimise overall gearing for race, rally or rallycross use
• Standard factory synchromesh engagement for smooth selection.

QUAIFE Straight cut, close-ratio, dog engagement gear kit with revised final drive ratio
• Dog tooth engagement for rapid shifts, durability and strength
• Straight cut or ‘spur' gears to greatly reduce transmission power losses
• Closer gear ratios to maximise engine performance - ideal for highly tuned engines with narrower power bands
• Often features taller first gear for race and rally applications
• Some kits upgrade from 5 to 6-speeds
• Wider gears to improve durability
• Several lower final drive options to optimise overall gearing for race, rally or rallycross use
• Gear kits often include bespoke selector forks for added durability

QUAIFE Straight cut, close-ratio, sequential transmission, revised final drive ratio
• Sequential action - ultra-rapid gear changes at the push and pull of a lever
• Dog tooth engagement for durability
• Straight cut or ‘spur' gears to greatly reduce transmission power losses
• Closer gear ratios to maximise engine performance - ideal for highly tuned engines with narrower power bands
• Often features taller first gear for race and rally applications
• Wider gears to improve durability
• Several lower final drive options to optimise overall gearing for race, rally or rallycross use
