Hydraulic Coilover Lift System by KW Suspensions®. KW Suspensions offers hydraulic coilover kits with lift cylinders that offer the ability to raise lowered vehicles 1.8 inches, and conversion kits that include lift cylinders with just the hardware needed to convert OEM electronic leveling shocks or air springs to KW coilovers (the coilovers are not included in conversion kits).
For those with lowered vehicles that have trouble with ground clearance over banked driveways, tall speed bump, and support arms on standard 4-post lifts most repair shops use, KW Suspensions offers Hydraulic Complete Lift Systems in front-only and 4-wheel sets. You’ll get KW’s Variation 3 coilovers for optimal performance – each with an additional hydraulic lift cylinder unit mounted between the spring perch and spring. These expand to provide 1.8 inches of front lift when lowered vehicles need extra clearance. Lift can be activated at speeds of up to 50 mph from a hardwired control switch. Layout creates no additional suspension movement or reduction of control while driving.
The coilovers themselves are a twin-tube dampening design formed of an inner tube element within an outer tubular element. Coil springss are constructed with a multi-level tempering process that includes an annealing stage which heats the metal, then allows it to cool slowly in order to remove internal stresses and increase strength. Metal is then shot blasted to remove surface imperfections and coated with a durable outer finish to minimize vibrations and resist corrosion. Corrosion-free stainless steel strut casings feature dirt-resistant threads to ensure easy adjustment in all climates and dust levels, and a high-quality elastomer synthetic compression buffer serves as an additional spring. An integrated dust cap ensures grit and the elements do not reach inner valve areas.
