These are bolt-in replacement coilovers from Fox Shox.  Sold in pairs. These are 2" dia bodies with 5/8" shafts (similar to most 2" shocks/coilovers). These use Eibach springs too. These come ready to install and will offer 1.5-2.5" lift on 4wd Titans depending on year and current stance. These ride really well and ride height can be adjusted but the spanner wrench is NOT included. These typically drop ship for a Fox warehouse.
