Wilwood Steering Arms: Precision Engineering for Custom and Race Builds

When it comes to suspension and steering components built for demanding performance applications, Wilwood Engineering brings the same exacting standards to its steering arms that have made the brand a legend in high-performance braking. Wilwood's steering arms are not generic replacement parts — they are purpose-engineered components developed alongside the brand's own ProSpindle system, creating a cohesive front-end solution for builders who refuse to compromise.

The ProSpindle Steering Arm Advantage

Wilwood's steering arms are part of the renowned ProSpindle product line, which represents a ground-up rethinking of front spindle and steering geometry for custom applications. These steering arms are specifically designed for use in fabricated A-arm suspensions on kit cars, street rods, drag cars, and other custom or race applications configured around Pinto/Mustang II suspension geometry.

A redesigned one-piece forged steel body uses common Pinto and Mustang II tie rod ends, ball joints, wheel bearings, and seals. This compatibility with widely available hardware keeps builds practical and serviceable without sacrificing strength. In fact, the design is lightweight yet nearly 3x stronger than OE or aftermarket 2-piece cast iron and steel replacement spindles.

Versatility Built Into the Design

One of the most practical features of Wilwood's bolt-on steering arms is their inherent flexibility. The bolt-on steering arms are strong and can be reversed to accommodate rear steer configurations, and they also allow the same spindle to be used on either side of a vehicle. For custom builders working on tight packaging constraints or unconventional suspension layouts, this reversibility is a genuine advantage that saves time, cost, and complexity.

The integration between Wilwood's steering arms and their spindle systems goes even further. Bolt-on caliper brackets attach to substantially reinforced mounting bosses on the spindle body for secure, deflection-free mounting of 4- or 6-piston calipers. This means the steering arm is not just a steering component — it's part of a fully integrated front-end package that pairs seamlessly with Wilwood's world-class brake hardware.

Stock Height and Drop Configurations

Wilwood Engineering offers 2-inch drop spindles and stock height spindles and steering arms for both street and racing applications. Whether a builder needs to maintain factory ride height for a street-driven hot rod or achieve a lowered stance for a dedicated race car, Wilwood has a configuration ready. The 2-inch dropped spindle pin provides the desired lowered ride height without disturbing the suspension geometry, a critical detail for builders who want the look of a lowered vehicle without sacrificing handling precision or bump-steer characteristics.

A Trusted Name Across Motorsport and Beyond

In addition to designing and manufacturing brakes for all types of competitive motorsports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles, and military vehicles. That breadth of engineering experience is reflected in every component the brand produces — including its steering arms, which benefit from decades of metallurgical and design expertise. For custom builders, restorers, and racers who demand that every part of the front end meet the same high bar as the brake system, Wilwood's steering arms deliver a cohesive, proven solution.
