Twin I-Beam Front Suspension Kit – Ford F-100 Pro Touring (3" Drop)

The Collino Twin I-Beam Front Suspension Kit is a complete Pro Touring front suspension system engineered to dramatically improve steering precision, suspension geometry, and high-speed stability while maintaining the original Twin I-Beam architecture that made these trucks famous.

Designed for a 3-inch (76 mm) front drop, this system delivers the aggressive stance expected from a modern Pro Touring build while preserving suspension travel, ride quality, and factory mounting locations.

Unlike traditional lowering methods that compromise alignment and steering geometry, the Collino system has been engineered from the ground up using CAD design, CNC manufacturing, and extensive real-world testing.

Spindle Compatibility

This suspension kit is available in two different versions, depending on the spindle installed on your truck.

Both versions maintain proper steering geometry and are specifically engineered for their respective spindle design.

Option 1 — Original Drum Brake Spindles

Designed for original Ford 7/8" kingpin drum brake spindles, which use bolt-on steering arms.

This version includes:

• Bolt-on steering arm components
• Correct steering arm height
• Proper Ackermann geometry
• Direct bolt-on installation
• No cutting or welding

Ideal for:

• Original drum brake trucks
• Restorations
• Trucks using aftermarket disc brake conversions based on original drum brake spindles

Option 2 — Factory Disc Brake Spindles

Designed for original Ford 7/8" kingpin factory disc brake spindles, where the steering arm is cast as part of the spindle.

This version includes:

• Precision-machined steering arm relocation adapters
• Correct steering arm height after lowering
• Maintained steering geometry
• Installation is primarily bolt-on; however, drilling and thread tapping of the steering components are required as part of the installation process. Full instructions are provided.
• No cutting or welding

This solution allows factory disc brake trucks to retain proper steering characteristics after the 3-inch drop.

Construction

Every component is engineered for strength, durability, and precise suspension alignment.

The kit features:

• CNC laser-cut steel components
• Heavy-wall tubular construction
• Precision MIG welds
• High-strength hardware
• Corrosion-resistant finish

The adjustable radius arms allow precise caster adjustment while reducing suspension flex during braking and cornering, providing a significantly tighter and more responsive driving experience.
