Ford F100 Twin I-Beam Adjustable Radius Arms

For Original Ford I-Beams and Collino 3" Drop I-Beams (Set of 2)

The Collino Adjustable Radius Arms were engineered to improve the geometry, alignment capability, and overall performance of Ford F100 Twin I-Beam front suspensions while maintaining a true bolt-on installation.

Unlike the original fixed radius arms, the Collino design incorporates an integrated caster adjustment system, allowing precise front-end alignment without modifying the suspension or using aftermarket correction components. Proper caster adjustment significantly improves straight-line stability, steering feel, high-speed control, and steering wheel return after cornering.

These radius arms are fully compatible with both original Ford Twin I-Beam axles and Collino 3" Drop Twin I-Beam Axles, making them the ideal solution for restorations, Pro Touring builds, performance street trucks, and custom projects.

The rear mounting system retains the original Ford-style rubber bushings and uses the factory chassis mounting location and original mounting bolt, ensuring excellent durability while maintaining vibration isolation for comfortable street driving.

Manufactured from high-strength steel and precision welded, each arm provides exceptional rigidity under heavy loads while remaining suitable for everyday driving, towing, and high-performance applications.

Designed as a complete bolt-on upgrade, no chassis modifications are required.
