#1 WHAT PSI SHOULD I RUN IN MY SHOCKS?
We advise running 180 psi of nitrogen in all of the shocks we manufacture. This needs to be set with the shock fully extended “can be fully extended on the vehicle”. The nitrogen charge effects the performance of the shock, you can run a higher nitrogen pressure than that but that does not effect the compression of the shock like most people think it will mainly increase the rebound speed of the shock. The nitrogen charge also loads all of the seals an o-rings a shock that has not been charge will sweat.
#2 WHAT MOUNT WIDTH DO I NEED?
We offer all of our shocks with either a 1.5” or 1.25” mount width. This is the dimension of the shock rod end with both mis-alignment spacers installed. The 1.5” option is the most common and will have slightly more articulation than the 1.25”.
#3 HOW TO INSTALL DUAL RATE SPRINGS?
step 1 : Fully extend the shock you can extend the shock by charging it with nitrogen or by manually pulling out on the lower rod end.
step 2 : loosen the allen bolts on the upper preload adjuster as well as the dual rate stop. The upper preload adjuster is the main adjuster that the springs will rest on, it has only 1 allen bolt in it and is closest to the shock top cap. You will then want to rotate the upper pre load collar to the top of the shock.
step 3: Slide your tender spring”this will be your upper spring usually shorter than the primary and lighter in weight” over the shock shaft and let it rest on the upper retainer.
step 4: Install your spring divider “the black piece the will sit between your 2 springs” some of our dividers one end is longer than the other if that is the case face the longer end of the divider up. Pointing to the top cap of the shock.
step 5: Slide on your primary spring” the lower coil” After you slide on your primary spring you will want to slip in your lower spring retainer. You will then want to add preload to the springs to keep the lower retainer in place. You add pre load by turning the upper spring retainer until you remove any slack in the springs.
step 6: After you get the shocks mounted on the vehicle you will need to set your dual rate stop” the small stop with two allen bolts which is now under your tender spring. With the vehicle at ride height you will want to
