Key benefits at a glance

• Never Rust: One-piece forged T6 aluminum construction keeps weight down while resisting corrosion, even in snowy environments. Each arm is magnetically inspected for quality and consistency.
• Serviceable: A greasable socket helps flush contaminants and extend life. The ball joint is protected by tower dust boots and a dedicated protective cover to fend off debris. Zinc-nickel coated pins offer enhanced corrosion resistance over standard joints.
• Lift-ready and versatile: Designed for 2-4 inch lifts, it broadens the joint’s range of motion, aiding chassis correction while maintaining confident street and trail handling.

Durability and ride quality
