Harrop 2300 supercharger to Optimiser 6500

Feedback from ARB regards the shockers contacting the bump stop plate has been totally fair and supportive. Seems there is a note, admittedly in an obscure sequence of the instructions, to trim the bump stop plate if it looks like it will foul. So, on that basis, the error is mine, which I accept. Its been a really positive exchange with ARB Warranty at Kilsyth and the outcome is they will take the shockers back, rebuild them from their stock of spares - shockers are actually built in the USA, then return them to new. They will warrant the shockers as they stand for the full 3 yrs in recognition the instructions are not that intuitive. I am very impressed. At this time I have elected to drive it a bit further with the 'cosmetic damage' and then in the new year pull them off and get them rebuilt - its the bottom adjustment knob that has contacted the bump stop and become 'highly modified'. The mounting location of the remote reservoir is a bastard and another installation error I made with installing with the body 'off', then removal is difficult.
I was under the car today and shocker looking at the actual assy, think the issue is the shockers are too long for my suspension travel. I purchased the full F/R set during Covid and 4" lift was all they had left, so I made the decision to buy these - in hindsight 3" would have been better as the body is shorter - hence they probably would not have contacted the bump stops anyway.
I think I will have a pragmatic conversation with the warranty department, get the 4" rears rebuilt and buy a new set of 3" for the rear. I will then sell then 4" units. The ride is bloody good in all honesty, however the shorter body of the 3" will keep it away from the trimmed bump stops and the rear brake lines, so win win. ARB remain a trusted supplier in my mind.
