Mini and Moke damper Koni front standard height suspension shocks
Koni shocks are possibly the best name in shock absorbers, and they are available for Classic Mini and Moke cars. These are 20% uprated over Rover Mini standard specification  shocks and also rebuildable. The adjustment is for fluid degradation rather than performance increase, adjusting damper up does not increase damper performance , as it only makes it much stiffer (which is not the same thing)
Closed length from pin centres is 225mm. Sold singly but recommend fitting in pairs.
