Freeway Flyer Gearbox Rebuild / Upgrade, 65.7MPH @ 3,500RPM (002,091), T2 Bay 1967-79

Pricing based on Exchange! £100/£200 refund on receipt of your gearbox - dependent on your gearbox code, it must be in good, reconditionable condition and will be inspected on receipt.

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 185/80R14, standard gearbox ratios will achieve the following figures:

Standard Specs (4th Gear)
52.7MPH@3,000RPM
61.5MPH@3,500RPM
70.3MPH@4,000RPM
79.1MPH@4,500RPM

Our conversion will convert any 3,5 or 6 Rib 1968-79 Gearbox, lowering cruising speed and stretching all gears by a percentage to mean no huge gap between 3rd and 4th, lower RPM means better MPG, higher top speed. For full details on other advised upgrades when carrying out a conversion see our tech centre.

Freeway Flyer Specs (4th Gear)
56.3MPH@3,000RPM
65.7MPH@3,500RPM
