Power is transmitted to the rear axle through an open type Hardy Spicer shaft with both propeller shaft universal couplings being needle roller types.

The DB2 & DB2/4 MkI was fitted with a 3HA Lightweight Salisbury axle and the DB2/4 MkII had a 4HA heavyweight version.

Parts availability for the 3HA is poor due to only being used on the early cars as it proved to be inadequate and was replaced with the stronger 4HA axle.

Availability of parts for the 4HA is good and it is possible to convert an early car which currently has a 3HA axle to accept a 4HA, contact us for further details and prices.

The following is a selection of replacement parts that are available for the 4HA Axle.
