2015-2019 F-150 Coil-overs & Rear Shocks

*To be used with our coil-over and rear shock relocation brackets.*

Warrior Series: digressive valved shocks and struts for vehicles driven mostly on the street with occasional track use.
Crusader Series: digressive/progressive valved shocks and struts for application specific vehicles. (Drag Racing)

To select the correct shocks for your truck, please measure the desired ride height (ideally it is best to order our brackets first to get the exact eye to eye measurement).

Please allow 3-4 weeks ETA as these custom shocks are built to order.
Now includes thrust bearings and spanner wrench!

To determine the correct spring rate, please follow the steps using the diagram in the product pictures:

  • D1: The distance from the pivot point of the control arm to the mounting point of the shock/spring.
  • D2: The distance from the pivot point of the control arm to the center of the ball joint.
  • Step 1: Divide D1 by D2 to determine your force ratio (Fr)
  • D1/D2 = Fr
  • Step 2: Determine the sprung corner weight (SCW) (weight on one wheel)
  • Divide the SCW by Fr to determine the force requires at the spring (Sf)
  • SCW/Fr = Sf
  • Calculate the Adjusted Spring Force (Asf) by dividing the Spring force (Sf) by the Angle Correction Factor (Acf)
  • Asf = Sf / Acf
  • The actual spring rate can now be calculated using the following equation:
  • Actual Spring Rate = Asf / spring length x 0.25 for a firmer spring rate
  • Actual Spring Rate = Asf / spring length x 0.3 for a softer spring rate
