I just put it in my wife's 2000. I paid $150 plus tax from a local FRPP distributor. You will need to install cam bolts to get the truck back to stock alignment. These replace the bolts attaching the upper control arms to the chassis. NAPA part # is 264-2953 and you will need two sets. About $33 total.

And when installing the cam bolts be sure you remove the rectangular plates under the stock bolts since they restrict movement of the cam bolts. Go ahead, ask how I know…
