After some carefull measuring and designing I could come up with a workable solution to enable the mounting of Defender* calipers and discs onto a Series, II, IIA and III axles. I came up with a modified swivel housing and a modified wheel hub.

Both cast from nodulair cast iron, which is much stronger then the grey iron used by Land Rover for the original swivels and hubs. All are CNC machined and in-house quality checked. The complete production, from casting the iron to  machining and finishing, is done here in The Netherlands.

*) Discs and calipers from Discovery SI and Range Rover (classic), ventilated or non ventilated, can also be used.
