The Formula F4R lift kit for PX I & PX II is a 3-way adjustable remote reservoir coil-over system in the front and a 2-way adjustable remote reservoir shock in the rear, specifically designed to suit your vehicle. The damper uses Fulcrums own high flow digressive piston with carefully chosen shim stacks to create the best damping characteristics for each vehicle.

The front damper is 3-way adjustable, spring pre-load, compression bypass and rebound bypass. The rear damper is 2-way adjustable, compression bypass and rebound bypass.

The adjustment clickers allow the user to carefully control how much oil is allowed to bypass the shim stacks in each direction. Opening the clickers allows more oil to bypass, reducing the damping effort in either compression or rebound. This allows tuning for different load scenarios and road conditions.

This Formula F4R Adjustable Remote Reservoir Kit is preset to:
  • Front: 63mm or 2.5" Lift with Bull Bar & Winch (adjustment up to 75mm or 3" or to be lowered if required)
  • Rear: 63mm or 2.5"


Note: 3 inches of lift is not road legal unless mod plated. If you set your ride height to 3 inches, then it should only be for offroad use.
