I just bought a Cat with big bores on it and although I didn't build the original ones I stripped it down to clean and setup and found 2 of the 4 shocks had loose caps on the bottoms where the seals are...
might just be a 1 off build issue from previously, but I thought it was a bit weird.
Found rebuilding them with fresh oil a doddle to do and made 2 perfect shocks quickly and stress free
