[QUOTE="mikepipe597, post: 1344750, member: 12889"] Besides our initial settings there is no other guideline on how to adjust the shocks since everybody has a different need/want out of their suspension. The initial settings are what we found to be a good balance between street handling and off road performance. If you choose to adjust the shocks here are descriptions of how the adjusters work. The orange knobs that face down are the compression adjusters. The black knobs are the rebound adjusters. All adjustments are done starting at fully closed which is all the way clockwise. On the compression tubes, the short compression mainly effects ride zone( this can change if you have changed the ride height with different leaf springs, load, etc.), the longer compression tube effects the bottom out resistance as well as ride zone (notice the tubes overlap each other a bit). The easiest way to adjust compression is to work with the long tube until desired bottom out resistance is achieved. Then adjust short tube to achieve desired ride comfort at ride height. Rebound is adjusted the same way as compression. The long rebound in this application is substituted with the cooler ports which act as a long rebound tube. It is important not to make the rebound too stiff because it will cause packing which will cause the wheel to not drop out fast enough which will make the truck feel harsh and may make you reduce compression stiffness to combat the ride harshness. This will drastically reduce off road performance. Rule of thumb on rebound is to have just enough rebound stiffness that the wheel is able to drop freely but the truck does not feel too loose.

High speed is large grey knob and low speed is smaller orange knob. High speed is adjusted from full open (full open is all the way counter clockwise) and low speed is adjusted from full closed (full closed is all the way clockwise). High speed adjuster affects fast suspension movements, ie hitting a curb at 30 mph. Low speed adjuster affects slow speed suspension movements, ie undulations on the freeway.
