These are tall. The top mount to centerline on the lower bolt is about 22.6". this is correct for the Fabtech, RC 6", and CST 7" kits. Depending on application, you may need to run a high-clearance upper arm (any brand really). We can shorten the shocks but it does void Bilsteins waranty. The point of these shocks is to offer the bracket lift guys with the tall spacers a chance  to ditch those or for the guys tired of rebuidling their race-style shocks and chance for a budget-concious option that rides really well.
Spring options are 600 or 650lb (use the 650 is adding a heavy front bumper or winch). These typically take about 1-2 weeks to assemble, if you are in a rush, EMAIL us.  We will typically call if you order from the website to make sure these are the right shocks for you. if weve corrosponded previously, we probably wont call.
