Genuine Mini Spares product as originally produced for the MPI with 13" wheels.
It has the larger width cone spring base size of 3.7" with a fitted length of
12.4"(315mm) which is 7mm longer than some other factory parts all stamped 21A1684.
Also ideal for Mokes and believe it or not this length was used on Cooper S Mk1 with 10"wheels using BMC's own strut stamped MOWOG 21A1302 which had a 12.48" fitted lenth, but with early manufactured cone springs. With modern day suspension cones such as
FAM3968EVO which do not sag but we cannot advise how high the suspension would be using this strut. Many cars were fitted with these during the 1980-90's which is why many cars sat high on the rear. Ratio is 5 to 1 on rear.
Fitted length is from cone spring seat base to knuckle joint end
