Formula F4R Shocks

The F4R range of shocks are boasted as one the top of the line remote reservoir shocks on the market. With 45+ years of suspension engineering knowledge backing the design of these new remote reservoir shocks. The Fulcrum & Formula engineering team have built the most comfortable remote res shock on the market. Combined with Fulcrum's 4WDing passion and experience, you now have the best remote res lift kit at your finger tips. Built for comfort and performance, Formula F4R shocks are tough yet comfortable.

Formula F4R Remote Res Shock

Designed specifically for the 4WD market and benchmarked against the industries best. The Formula F4R Remote Reservoir shocks offer the best performance and the most comfortable ride onroad and offroad, bar none. 


 

  • An ultra-adjustable (26 click) remote reservoir shock, valved to maximise comfort & performance in all types of terrain.
  • Improved Cavitation resistance, giving greater driving consistency on the roughest roads and toughest tracks.
  • Built tough with a steel body, massive bore, custom piston & light 6061-T6 aluminium supports.
  • Designed to provide sharp handling on and off road, whilst giving an extremely comfortable ride.
  • Precisely calibrated, with vehicle specific damping and a large custom piston to control performance + comfort.
  • Increased oil volume and thermal capacity, providing consistent and dependable performance.
  • The F4R damper adjustment range is designed to accommodate a variety of springs, loads & heights.
  • Fully Customisable & Rebuildable

The Formula F4R lift kit for the Y61 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.


Formula F4R shocks


This Formula F4R Adjustable Remote Reservoir Kit is preset to:

  • Front: 50mm or 2" 
  • Rear: 50mm or 2"

*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. Fulcrum Suspensions does not take responsibility for the incorrect usage of this lift kit. 

 Formula 4x4 Lift Kit Warranty

Formula 4x4 lift kits come with a 5 year / Unlimited Kilometre warranty.


Description of Shock
The F4R Formula 4x4 kit is a 3-way adjustable remote reservoirs shock for IFS vehicles, 2-way adjustable remote reservoir for solid front axles and 2-way adjustable remote reservoirs shock in the rear, specifically designed to suit your vehicle. The damper uses Fulcrums carefully chosen shim stacks to create the best damping characteristics for this vehicle.

The front damper is 3-way adjustable, Spring seat height, compression Low-speed bypass, compression high-speed valve and rebound bypass. The rear damper is 2-way adjustable, compression Low-speed bypass, compression high-speed valve and rebound bypass. The adjustment clickers allow the user to carefully control how much oil is allowed to flow and
bypass the shim stacks in each direction. Opening the clickers allows more oil to bypass and flow, reducing the damping effort in either compression or rebound. This allows tuning for different load scenarios and road conditions.

Shock terminology
When discussing the damping performance of a shock, it is in the terms of force require to move the shock at a certain speed – meaning the speed of the shaft moving in or out of the shock body. Rebound is referred to the extension of the shaft moving out of the body and compression the shaft moving into the body.

How to tune the damping settings
It is important to remember whenever tuning a passive damper, every adjustment is a compromise. An improvement in one area of ride and handling will detract somewhere else. The aim is to create the best compromise for your driving style and scenario. As a basis, compression is generally lower in forces require to move than rebound. On compression of a shock (wheel moving into the guard) you have both spring and shock working together to absorb the bump and control the car. When the wheel is drooping or moving away from the guard, the shock will need to control the unsprung mass – which is all components that are not held by the spring (wheels, tyres, hubs, axle etc.) as well as the force of the spring wanting to extend. It can be sometimes difficult to interpret how the suspension is performing and what adjustment may be required depending on the terrain being driven on, vehicle loads and set up as well as the drivers’ requirements or wants from the vehicles handling performance.

Please see the following guide to help on what may be required in adjustments to aid in vehicle shock tuning.

Problem Damper Adjustment
Car easily bottoms out. - More high-speed compression.
Car feels lazy or unresponsive. - More low-speed compression.
Car feels too harsh over bumps. - Less low-speed compression on small bumps/Less high-speed compression on large bumps
Car Kicks off bumps. - More rebound.
Car feels floaty. - More rebound.
Car is harsh over cracks or potholes. - Less rebound.
Front is too high. - Reduce front spring pre-load.
Front is too low. - Increase front spring pre-load.

Use of adjustments
Please note that before making any adjustments you should always make a note of what settings you have and what you change them too. This will ensure you keep track of the positions and don’t get lost. If you are ever unsure wind the clickers all the way clockwise and count back out to the desired position. Each clicker has direction of positive (more damping) and negative (less damping) listed on their surface.

Fulcrum recommends the following damping settings as a starting point. (Note that this number of clicks anti-clockwise from the fully closed position.)
Front and rear Compression Low: 4 clicks (1 to 8 total) – Small adjuster on reservoir
Front and rear Compression high: position 3 (1 to 6 total) – large adjuster on reservoir
Front and rear Rebound: 2 clicks (1 to 12 total) – on shaft end mount, blue adjuster or silver pin clicker depending on vehicle
