The next step of the shock build up is installing the shock piston.
This is where I believe that Axial steps it up and provides you with one of the most adjustable shocks on the market. In the shock kit Axial provides you with 3 different standard pistons offering different dampening levels from Soft to Firm. Axial also provides Variable Rate Pistons in the kit. The variable rate pistons allows you to have a faster rebound/slower compression or a slower rebound/faster compression choice.
I decided to install the Soft Dampening pistons.
I have laid out the parts in the picture below, in the order the parts are assembled.
I installed one flat washer onto the shock shaft, then slide the piston on next, followed by the second flat washer. I then used needle nose pliers to hold the lower portion of the shock shaft on the flats. I then threaded the M2.5 Nylock nut onto the threaded portion at the top of the shock shaft and tightened the nut down. (DO NOT OVER TIGHTEN THE NUT) Tighten the nut until it just stops.
This is where the build up differs from Benders Axial build up. Because I am using JeepinDougs C-cups, the installation of the springs, spring retainer, and the rod end will be installed at a later time in the build.
I moved forward to the threaded aluminum shock body build up.
Once again I have laid out the parts to show you the order the parts for this portion of the build are put together.
The first thing I did was to install the o-ring into the threaded pre-load collar.
Next I installed the threaded pre-load collar with the o-ring installed onto the threaded aluminum shock body. Make you install the threaded pre-load collar onto the threaded aluminum shock body with the flange facing the unthread portion of the aluminum shock body.
You will want to thread the threaded pre-load collar about half way down the shock body.
Next is to install the shock bladder into the shock caps. You will need to find something soft to work the bladder into the shock cap. You do not want to damage the bladder. I followed Benders lead and used a plastic pen cap.
Now it's time to thread the cap on to the shock body. Tighten down the cap as tight as you can with your fingers. Do not use pliers or a wrench. If you do you will increase the chances of unseating the bladder which will cause the shocks to leak. I perfer bleeding the shocks when I install the shock cartridge assemby into the shock body. That is the way I learned to do it in the past, but you can bleed them through the cap if you perfer that method.
