T1 -1979 Super Flyer Gearbox Rebuild / Upgrade, 81.8MPH @ 3,500RPM

Classic Aircooled VW Complete T1 Gearboxes parts by Limebug

Pricing based on Exchange! Pickup and Drop Off Service. Need more from your gearbox to keep up with modern traffic speeds, you are not alone.

This upgrade is not the typical swap out for a taller 4th gear, we instead convert the gearbox ring and pinion to move all the gears by a percentage therefore gear spacing remains even and will not over strain the drivetrain.

Based on original tyre dimension of 195/65R15, standard gearbox ratios will achieve the following figures:

Standard Specs 4.375 (4th Gear)
54.8MPH@3,000RPM
64.0MPH@3,500RPM
73.1MPH@4,000RPM
82.2MPH@4,500RPM

Standard Specs 4.175 (4th Gear)
58.1MPH@3,000RPM
67.8MPH@3,500RPM
77.5MPH@4,000RPM
87.2MPH@4,500RPM

Our conversion will convert any Swing Axle or IRS gearbox to a super flyer, this will increase your motorway cruising speed, as with our T2 Bay Window gearboxes we offer three configurations of gearboxes, Freeway Flyer, Super Flyer and Ultra Flyer.

If in any doubt of whether your vehicle will be compatible with a certain spec gearbox, please get in touch, we accept no responsibility or liability for unsafe or incompatible unions.

Super Flyer Specs (4th Gear)
70.1MPH@3,000RPM
81.8MPH@3,500RPM
93.5MPH@4,000RPM
105.2MPH@4,500RPM
