My main thing is, how is the front of the ram sealed. Whether it be an o-ring or actual U-cup seal? Thats about the biggest obstical I'm having to over come.

Thanks for the information though.

Tyler , on a real 1 : O-rings with backup rings and a wiper seal . For what we do just an o-ring . Real 1's use chrome rods (polished) thats what you want to have . I use 304 L ss from online metals . From the mill it comes very smooth . Another issue could be your piston seals are too tight . Looking at you ram pics , def. too course . I should note , if your cap (gland) is cocked in the slightest way that will make it leak also .
