The seals are not bad on the shockshafts but can be rebuilt if u want to.Here is a picture of my shock set-up,instead of 10,i have 6 shocks on my truck with Rexx X buggy springs and 40 series Moab on standard Genesis rims,it can be done just a nice thight fit and grips very well! Have a look at this picture ,there are 3 more on this site,just search for them.I use 35weight shock oil.http://totalrc.co.uk/pics/displayima...&cat=0&pos=206
