2017-2018 Ford Raptor 4" Suspension System. This new lift system for the Raptor is based on the popular BDS 4" system for the standard F150s. Many of the components from the standard F150 kit carryover like the ductile cast iron steering knuckles, laser cut/CNC formed, fully welded crossmembers and differential brackets, etc.
We determined in testing that the 4" lift height allows for the best use of the full range of suspension travel allotted by the factory suspension components. These factory components include the high-end Fox Racing Shox at all 4 corners of the vehicle. These internal bypass coilovers (front) and shocks (rear) are what really make a Raptor the truck it is.
By properly relocating these coilovers and shocks, we are able to maintain that amazing performance that makes the Raptor a true offroad machine. The front coilovers are relocated with a heavy-duty spacer at the frame mount while the rear shocks are relocated at the axle with bolt-on brackets.
Other Raptor specific items included in the kit are front brake line relocation brackets that maintain adequate brake line slack for the massive amount of wheel travel available. Raptor specific front skid plate relocation is also included to maintain the signature Raptor front aluminum skid plate and have it blend cleanly into the BDS front crossmember.
Out back, in addition to the rear shock relocation brackets, is a 5" block and u-bolt kit. The 5" block replaces the factory block to net a level stance and includes a bump stop wing for proper bump stop engagement offroad.
