One end of the ride height adjuster is reverse threaded, it is the end with the "cut marks" in. Simply loosen the lock nuts at either end and then adjust. make sure that you take a measurement from the axle nut to a point above so that you can gauge how much you have altered the height by. I have a ride height tool and as andyB said there are some for sale on here. Get a ride height tool before you start and then you have a fixed point of reference for any changes. Sadly I cannot remember the spanners sizes but 17mm & 19mm rings a bell. Mike |
