HARDY SPICER COUPLING ASSEMBLY

Hardy Spicer was the original company behind the driveshaft couplings and CV joints on the Mini, an essential component for the front-wheel-drive layout, which was rather unusual for the late 1950s. The company later developed pot joints, which would go on to replace these crucifix-style universal joints in the 1970s. Hardy Spicer has not produced these joints for many years, and no longer exists in its original form, but the name has stuck.

Pot joints were an improved design, but over the decades, competition Mini owners in particular have come to prefer the Hardy Spicer-style couplings. Our version is especially robust, rebuildable and also gives good exhaust manifold clearance. We also find it easier to remove a competition Mini engine in a hurry with these compared to pot joints.

Yes, MED joints feature CNC-machined billet EN24T steel outer sections for superior strength, where the originals can break under heavy load, especially on old joints or budget aftermarket replacements.

These sections, known as a slip joint, are adapted from another heavy duty driveshaft application, so when we use them for the Mini, this external threaded section is not used.

No, as they are more substantial than standard, we do not have a suitable rubber boot/gaiter for the joints. We have not found this to be an issue in any competition Mini. If used regularly on the road or for autograss or rallying, keep the joints clean and with a spray of white lithium grease or similar.
