Eye to eye so you can bolt through them. I beleive they where 700 long extended but you would take your own measurements to optimise the amount of lift. I have mine set to 500N but I need to get them pumped up a bit. 600-700N would be better with the tinny. You can get them made to your spec I:E if you want different ends and pressures they just screw new ends on and change the pressure ( can only INCREASE the pressure though, you go to hard they are fucked). Cant remember what I payed. I remember the anchor thought it was extausion and I thought it was fair ( She's tight as hell.... With money...).
