1999-2004 Ford Super Duty
6" / 8" 4 Link Coilover Conversion
A. Tubular Coilover bucket w/ 1/4" thick steel frame plate
B. Dirt Logic 4.0 Coilover
C. Adjustable 2" OD Trac Bar w/ 1-1/4" Heims
D. Large 2" OD 4 Link Arms w/ 1" Spherical Bearings
E. Optional Dirt Logic 2.25 hydraulic Bump Stop


4 Link Frame Bracket
With the popularity of our 8” Coilover Conversion system for the 2000-2004 Super Duty we now offer a similar 6” Coilover system for the Super Duty and Excursion. This 100% bolt on 6” 4 Link Coilover conversion system utilizes large 2” OD Links with race style 1” spherical bearings for superior strength. The 4 link arms attach to the frame with bolt on 1/4” thick steel brackets. The link arms are attached to the factory front axle housing with massive 1/4” thick steel brackets that surround the housing and secure the 4 Link Arms for heavy offroad use. Due to the increased side load of a 4 Link suspension we include a replacement 2” OD Trac Bar with 1-1/4” Heims to properly locate the front axle throughout the travel range. The Dirt Logic 4.0 Coilover shocks attach to the frame via a large hoop style shock bucket and to the axle, integrating into the 4 Link axle brackets. The factory sway bar is relocated with billet sway bar links while triple layer limiting straps control the extended wheel travel of the front suspension. This system will provide a substantial ride quality increase both on and offroad. To complete this high end system, opt for our front Dirt Logic Hydraulic Bump Stops. Rear systems include block and add a leafs, replacement leaf springs or a Long Travel Leaf system.

5.5" / 8" 4WD PERFORMANCE SYSTEM
Our Performance systems offer more than just increased ride height. The progressive thin 10-leaf front spring pack rides on nylon glide pads for a superior ride. Front springs include military wrapped front eyes with 4 leaf clamps for exceptional strength. Rear lift is accomplished with a block and add a leaf or complete rear spring.
kit 1999-04 SUPER DUTY REAR SPRING & HANGER SYSTEM
This rear system was originally developed to compliment our front Coilover Conversion system to provide increased rear suspension travel with a smooth ride for both on and offroad use. The system will provide similar ride quality enhancements when used with our 6” or 8” Radius Arm and 4 Link systems with single or multiple front shocks. For vehicles with a 6” ride height there is two rear configurations available. Option one would include our 3” heavy duty Spring Hanger bracket kit that directly replace the factory units while retaining the stock lift block and stock leaf springs, keeping the factory ride and load carrying capacity. Option two would be our replacement 3” Long Travel Leaf Springs that utilize the stock spring hangers and stock lift block. This second system will provide a smooth ride due to the Long Travel Leaf Springs with greater travel but stock weight carrying capacity will be reduced. Vehicles with a 8” ride height would receive the replacement 3” Spring Hanger brackets and 3” soft ride Leaf Springs using the stock lift block. This set up will provide a smooth ride with increased travel and articulation but stock weight carrying capacity will be reduced.
kit 3.5” FRONT SPRING AND SHACKLE HANGER SYSTEM
This system features our heavy-duty front spring hanger brackets with replacement extended length shackles. The extended length shackles provide for an easy install with increased leaf spring flexibility. This system will provide a front end ride height increase of 3.5” without changing the leaf springs. 2001-04 Super Duty’s and all Excursions systems include a replacement front frame crossmember and bumper brackets.
kit 3.5" FRONT SPRING HANGER SYSTEM
Obtain 3.5" of front end lift without changing the front leaf springs. The super stout spring hangers replace the factory units without welding or cutting. Excursion models will require a 2" rear block kit to level off the ride height. 2001-04 Super Duty & all Excursions systems include replacement front frame crossmember and bumper brackets.
kit 2000-04 SUPER DUTY TORSION SWAY
BAR SYSTEM

Stock sway bars are fine for non lifted applications
as the factory designed them for, but for additional
stability with a lifted vehicle our new Torsion Bar
Sway Bar systems are the ticket. As found in
many racing applications our new Torsion Sway
Bar system utilizes a splined torsion bar with
adjustable side plates and billet links with heim
ends. This system is only compatible with our
Coilover Conversion systems.
SUPER DUTY
FLOATING TRACTION BARS

These bolt on Traction Bars reduce rear leaf spring axle wrap caused by lift blocks and oversized tires. Typically the travel cycle of the Super Duty rear axle is in an arch, rather than a linear motion found in most other trucks. Fabtech’s exclusive traction bar shackle system allows the bars to float with the arched travel of the rear axle. This provides a non-binding, smooth highway ride but still provides positive resistance to torque loads, reducing leaf spring wrap and increasing tire traction.

DESERT GUARD
Constructed of 1 3/4" diameter tubing this guard mounts to the frame without having to drill holes.
ADJUSTABLE TRAC BAR

DUAL STEERING STABILIZER
OPPOSING STYLE

Stabilizer cylinders are mounted across the axle housing in a horizontal opposed position reducing tire shimmy.
MULTIPLE FRONT SHOCKS
Allows the addition of four more shocks to the front suspension for increased dampening capacity. Available for Fabtech shocks or Take - Apart Dirt Logic shocks.
kit kit
MULTIPLE REAR SHOCKS
System allows installation of four Performance or Dirt Logic shocks on the rear suspension. A tubular upper crossmember spans from frame rail to frame rail with triangulated gussets while lower mounts bolt to the axle housing. Allows use of the stock exhaust system.
DUAL STEERING STABILIZER
STOCK LOCATION STYLE

Utilizing the stock location, two steering stabilizers are positioned back to back from each other to reduce tire shimmy.
