Five Speed Conversions - MGB

Five Speed Conversions - MGB

Our 5 speed conversions provide everything you need to achieve modern day motoring comfort and performance.

The ultra-smooth action of the five-speed gearbox is an instant benefit. With synchromesh throughout the gear range and a quieter reverse gear the vibration and hassle are taken out of town driving. With similar ratios from first to fourth, the performance through the gears is unaffected, and the added benefit of a 0.82:1 fifth gear gives a reduction of approximately 1,200rpm at maximum speeds, giving faster and more relaxed cruising.

The conversion is based on the Ford T9 gearbox, it was chosen for its smooth gear change & robust reliability and spare parts availability. The conversion involves minimal cosmetic or structural changes and the specially modified gear change maintains the gear lever in the original position, with no modifications required to the upper area of the tunnel.

Installation kits are supplied separately from the gearbox unit. Please ensure you order the correct installation kit to suit your car and a gearbox unit. The gearbox is fully reconditioned and sold outright with no surcharge.

The installation kits include:

  • Bespoke cast alloy bell housing
  • Spigot bush
  • Modified Quick Shift gear lever Assy
  • Propshaft
  • Speedo cable
  • Mounting brackets
  • All necessary hardware

Notes: Reverse light switch is not included in the kit, but is sold separately. The original switch wiring will need to be modified to use this switch. The conversion uses a standard MGB clutch assembly. Installation kits do not include clutch components - we recommend the clutch is checked and replaced as necessary. If replacement clutch components are required Your speedometer will need to be re-calibrated to be accurate.

Our installation kits are available to convert the transmission configurations as detailed below.
