FRONT SUSPENSION COMPONENTS
2005–2022 Ford F-250 / F-350 4WD
The Pro One Design 2° Caster Correction Shim Is Designed To Restore Or Increase Positive Caster On 2005–2022 Ford F-250 And F-350 4WD Trucks. Precision Machined From High-Strength Steel, This Shim Installs Between The Radius Arm And Axle Mount To Improve Straight-Line Stability, Steering Feel, And Return-To-Center.
Our Pro One Design 4.5" And 5.5" Lift Systems Lower The Radius Arm Pivot Point By 4.5" To Maintain Proper Suspension Geometry And Preserve Factory Caster. Each Lift System Includes A 1° Caster Correction Shim That Increases Positive Caster Approximately 1° Beyond The Factory Specification For Improved Straight-Line Stability And Steering Feel.
If Your Truck Is Equipped With Pro One Design Fabricated Radius Arms, No Additional Caster Correction Shims Are Required. The Radius Arms Are Engineered With The Proper Caster Geometry Built In, Eliminating The Need For Additional Caster Correction.

Before You Install
Suspension modification notice. Installing this product modifies the suspension of your vehicle. A modified vehicle may handle differently than it did from the factory. Reduced speeds and different driving technique may be required, particularly in sharp turns and abrupt maneuvers. Always wear seat belts.
Alignment. Your vehicle will likely require an alignment after installation, at additional cost.
Headlamp aim. Check and adjust headlamp aim after installation.
Driver assistance systems. If your truck has camera- or radar-based safety systems, they may need to be re-aimed or recalibrated by a dealer after a ride-height change.
Read the instructions all the way through before starting. Installation by a qualified technician is recommended. Some modifications may not be legal in every state — check your local laws.
