This weld-on kit completely transforms your front suspension geometry, providing a longer arc of travel for smoother suspension movement, better traction, and improved off-road performance.

Designed for serious off-roaders, this kit features extended-length control arms, precision-engineered bracketry, and industry-leading materials, ensuring unparalleled handling, strength, and reliability. Whether you're conquering technical rock crawls, high-speed desert runs, or rugged trails, this front long arm kit delivers next-level suspension performance.

What's Included?

• Front Lower Long Arms (7075 Aluminum, 2” OD) – Maximum strength and flexibility with impact-resistant memory.
• Front Upper Long Arms (7075 Aluminum, 1.5” OD) – High-strength aluminum for optimal suspension control.
• Left and Right Front Frame Brackets (3/16” Steel, Weld-On) – Engineered for maximum durability and precise suspension geometry.
• Complete Installation Hardware – High-strength bolts, nuts, and washers for a secure and reliable installation.

Key Features and Benefits

• Optimized Suspension Travel Geometry – The long arm design extends the control arm mounting points, creating a longer suspension arc for smoother articulation, better traction, and improved ride quality. Reduces axle steer and bump steer, providing superior handling across all terrains.
• Ultra-Strong 7075 Aluminum Control Arms with ‘Memory’ – Constructed from massive 2-inch and 1.5-inch 7075 aluminum, these control arms flex upon impact and return to their original shape, maintaining proper suspension geometry and long-term reliability.
• Precision-Welded 3/16” Steel Brackets for Maximum Durability – All frame brackets are laser-cut and precision-bent from 3/16” steel, ensuring an unbreakable mounting system that eliminates flex and maximizes front-end stability.
• Full-Width Axle Compatibility Steel Arm Option – For optimal tire clearance and suspension geometry, full-width axles are recommended with 7075 aluminum control arms. If retaining factory-sized axles, we offer a steel control arm option with optimized bends for proper clearance and fitment.

Weld-On Installation for a Permanent Performance Upgrade

This kit requires cutting and welding, ensuring a permanent and incredibly strong suspension system. Professional installation is recommended for best results.

Recommended Pairing

Two-Stage Powder Coating for Maximum Durability

To ensure superior corrosion resistance and longevity, all control arms undergo a two-stage powder coating process. The first stage includes a zinc primer base coat for rust prevention. The second stage applies a durable topcoat, available in 10 colors, allowing you to customize your suspension components while ensuring long-lasting protection. Brackets are shipped in raw steel to allow for proper welding and post-installation finishing.
