1 The core piece of our front setup is the ICON coilover and upper billet control-arm kit. This kit eliminates the weak factory upper ball joint and replaces it with a Teflon-lined 1-inch uniball that aids in both strength and articulation. Camber and caster is adjustable to fine tune your truck’s alignment. The 2.5 coilovers are adjustable from 0 to 3 inches of ride height, use race shock pistons with flutter stack compression valving, have external reservoirs for maximum cooling, use Nitro steel shafts that will not chip or rust and are 100-percent made in the USA. The kit also includes sway bar relocation brackets and reservoir mounting brackets. This package can also be purchased for select Tacoma and 4Runner models.
