All BDS Suspension lift kits come with the security of knowing you purchased the finest lift kit in the aftermarket suspension industry. We back our commitment to engineering reliable, quality 4x4 off-road Jeep and truck suspension products with our unique "No BS Hardcore Lifetime Warranty".
If you are the original purchaser of any BDS lift kit and it breaks, we will give you a new part. Period.
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.

Shotpeening increases tensile strength and reduces fatigue while lessening the material thickness required. The thinner material allows for increased wheel travel and provides a softer ride.
Bolt-style leaf alignment clamps prevent leaves from fanning out and allow the leaves to twist and flex, yielding higher articulation.
Each spring is preset using hydraulic stress to reduce fatigue in the steel and prevent sagging.
Some applications include leaf springs with steel encased rubber bushings. Other applications include blue urethane bushings.
Anti-friction pads are placed between the leaves to reduce friction within the spring and noise from metal-to-metal contact.
Tapered and roll-pointed leaves add flexibility and provides an even deflection rate. Tapering allows a smoother transition between leaves as compression takes place, resulting in a softer ride with increased wheel travel.
Springs are either cold wound with chrome silicon 9254 or hot wound with 5160 to guarantee long life.
BDS coil springs are designed to withstand full coil bind. In other words, you can smash our coils to totally flat and they will return to their original height.
A polyester based powder coat is applied to ensure flexibility and durability.
Each spring is preset with a hydraulic stress to reduce fatigue in the steel and prevent sagging.
Shotpeening increases tensile strength and allows for maximum wheel travel without sacrificing the life of the spring.
