These are specifically for Titan Swap applications. Sold as a pair. We start with a set of Nissan specific 5100 front shocks (NOT the Tacoma/Tundra units), add our machined lower spring retainer and billet upper strut mount. These are assembled with your choice of Eibach spring and set to the height you'd like (from approx 3-5" lift). These simply bolt on, take them out of the box and install. These are about 18.5" long from  the mounting plate to the lower shock bolt....this is the appropriate length for a Titan Swap using just about any aftermarket upper control arms (dirt king, TC, rough country, SPC, Alldogs, etc). These take about 10 business days to build and ship, if you are in a hurry, please call or email before ordering. Note; the shocks shown in the pic have a Titan upper mount, the TS version is a small diameter but very similar.
