79 Series – Radius Arms – Superior Engineering – Billet

Over 20 Years of design, development, racing and testing have gone into bringing the absolute best Radius Arm’s available for Toyota Land Cruisers and Nissan Patrols.
Each Superior Engineering Billet Series Radius Arm is individually machined from a single billet of premium 7075-T6 Billet Aerospace alloy for incredible precision to create the ultimate package of maximum strength, lightweight performance and unmatched good looks.

Performance Benefits:

• High strength billet 7075 – T6 profile (significantly stronger than OE arms) is CNC machined for millimetre precision and the lowest possible weight.
• Lightweight 7075-T6 aluminium allows increased arm thickness while still being stronger and lighter than aftermarket BIS80 or 4150 “H” beam style arms.
• Retains OE bushings for strength, reliability and driving comfort.
• Oversized billet main beam section is CNC machined to maximise Articulation while increasing strength.
• Vehicle specific Lift height arms for correcting caster, tyre clearance and reducing driveline vibration.

Durability Benefits:

• Our unique beam section Solid Billet design eliminates bending or deformation.
• Impact resistance 7075-T6 aluminium has the reputation amongst the strongest grade aluminium alloy delivering a similar level of strength as many high strength steels while remaining a corrosion resistant and lightweight metal.
• Lightweight, high strength arms reduce diff and suspension weight allowing for improved ride and handling, taking stress off the shocks and springs for a smoother drive.
• 7075-T6 alloy will never rust or fatigue, so you can be confident in years of hassle-free driving.

Aesthetics Benefits:

• They look Amazing! The alloy arm has that precision CNC machined look in a stunning silver anodised finish.
• 7075-T6 alloy will never rust or fade, so you can rest assured those stunning arms will look great for a long time, without the typical fading or discoloration normally associated with painted or powdercoated arms.

High strength billet 7075 Alloy

High Strength Billet 7075 Alloy is a premium aluminum alloy known for its exceptional strength and durability. Its high zinc content, combined with trace elements like magnesium and copper, gives it properties comparable to many steels, making it ideal for demanding applications in aerospace, automotive, and military industries. This alloy’s impressive strength-to-weight ratio, excellent fatigue resistance, and ability to withstand extreme environments make it a top choice for critical structural components where performance is paramount.

Retains OE bushings

Supplied with OE/factory bushes ensures that the integrity and original performance characteristics of the vehicle are maintained. By using the factory-specified bushings, the Radius Arm fits seamlessly into the existing system, preserving ride quality, handling, and noise reduction as originally designed. This approach also simplifies installation and avoids the need for additional modifications, making it a practical choice for those seeking reliable and consistent performance.

Beam Section Solid Billet Design

The Beam Section Solid Billet Design offers unmatched strength and rigidity by utilizing a single, solid piece of billet material. This design eliminates the need for welds or joints, reducing potential weak points and ensuring uniform structural integrity throughout the component. Ideal for high-stress applications, this approach provides superior durability and performance, making it perfect for environments where reliability is critical.

Silver Anodised Finish

A silver anodized finish provides both aesthetic appeal and enhanced durability. The anodizing process forms a protective oxide layer on the surface of the aluminum, increasing its resistance to corrosion and wear. The sleek silver finish not only adds a modern, polished look but also ensures long-lasting protection against the elements, making it an excellent choice for both functional and aesthetic applications.

Vehicle-specific lift height

The arms are designed with vehicle-specific lift heights to ensure optimal performance for your 4×4. This customisation corrects caster angles, improves tire clearance, and reduces driveline vibrations, providing a smoother and more controlled driving experience, especially in off-road conditions.
