HFR Titanium Series Control Arm Builder Kits

Step into the next evolution of front-end suspension with the HFR Titanium Series Control Arm Builder Kit for Long Travel Struts—a premium, ultra-lightweight, competition-ready package designed for fabricators and racers who demand absolute precision, durability, and performance.

Engineered around our revolutionary HFR Billet Strut Knuckle, this kit delivers unmatched strength with drastically reduced heat transfer at the bearing surface. By increasing the distance between the bearing cup and weld zones, we eliminate unnecessary heat soaking—giving you more reliability, longer component life, and smoother articulation under extreme load.

Whether you’re fabricating a new setup or upgrading your existing race program, this kit gives you the materials and adjustability needed to build control arms that stand above everything else in the industry.

Material Advantage: Titanium Everywhere That Matters

All machined components are crafted from billet 6AL4V titanium—renowned for its superior tensile strength, corrosion resistance, and extremely lightweight characteristics.
All tubing is Grade 9 titanium, offering the ideal balance of rigidity and weldability for high-stress suspension applications.

Why Choose the HFR Billet Strut Knuckle?

This isn’t just another knuckle—it’s a complete rethinking of the interface between bearing, weld, and suspension load.
Our design increases the separation between the bearing cup and weld areas, which:

• Reduces heat saturation during fabrication
• Protects bearing surfaces from distortion
• Maintains precise geometry under extreme load
• Extends service life and reliability

It’s the foundation of the entire system—and the reason these kits outperform everything in their class.

Built for Racers. Built for Fabricators. Built to Win.

If your program demands the best in lightweight strength, adjustability, and titanium-driven performance, the HFR Titanium Series Control Arm Builder Kit is your new benchmark.
