Mini Spares 5 Speed Gearbox for classic Minis

Get the best of both worlds – acceleration and easy motorway cruising – with a Mini Spares five speed gearbox. All gearboxes come fully assembled and ready to install.

Both helical and straight cut gears are available and the gearboxes can be specified with either the original open differential, Mini Spares cross pin or limited slip differential.

The gearbox is suitable for 1275-1380cc engines (except those with extra boosted turbos). The gear case has undergone extensive modification and upgrading by Mini Spares with 58 improvements to the linkage and gear components.

The gearbox features a closer ratio gear set than the standard 4 speed gearbox by virtue of a redesigned laygear and first motion shaft which produce the following ratios-
1st gear 3.282
2nd gear 1.966
3rd gear 1.283
4th gear 1-1
5th gear is technically an overdrive gear and produces a reduction of .882 on the helical teeth gearbox, effectively giving a final drive ratio of 3.037 in 5th.

The Mini Spares 5 speed gearbox can be ordered as part number MSG05 (with helical gears and cross pin diff) at £2,295.00 inc vat. Please call for prices of other options. The gearbox is sold on an exchange basis with a surcharge of £250 pending the return of the old A Plus gearbox in a recyclable condition.
