I haven't yet but very interested too! 2 points ....wondering if ARB sells spare parts to rebuild them yourself and it seems they changed the numbers of the springs. Problem with the bypass is your ride height has to be spot on with the dampers otherwise the benefits are pretty much gone. m

I have just fitted the BP51 as a project with ARB/OME. Happy to help with what I can.

Can you explain why the ride height is so critical? 2007 110 TDCi Station Wagon XS

not sure exactly what you mean. We fitted these and were required for longer OME springs as well. I think they are worried that if you do not have the long travel springs in theory at full shock extention, you could pop the spring out. We also required DC drive shaft.

The bypass gives you a way to drive with 'different' valve settings across the entire shock length. Depending the amount of bypasses you have a more progressive one towards bump stop and a reduced rate towards full extension (nearly airborne/ deep wheeltravel). I had to use small spacers to fine tune the internal piston height to match it with the levels of bypasses. Try to find a drawing which shows the different levels of travel such a shock makes. They all work the same, external or internal. m
