Gearbox and Drivetrain Upgrades
For those wishing to modernise the Healey driving experience and make the car both faster and more enjoyable to drive we can fit our 5-speed gearbox. This is fully synchromeshed, makes for a much easier change and has the added benefit of greater power delivery to the wheels and less cockpit heat. We also offer differential changes to adjust gearing for lower rpm cruising and limited slip differentials to increase traction.
