What's included

• Driver-side knuckle box — cast knuckle assembly engineered for durability and precise suspension geometry.
• Passenger-side knuckle box — matches driver side for balanced front-end lift and handling.
• Diesel front kit box — heavy-duty fabricated components sized for diesel-engine weight distribution.
• Crossmember box — high-clearance design maintains optimal suspension articulation and off-road capability.
• Universal kit box — additional structural reinforcement and fastener hardware.
• Front kit box — laser-cut precision components for perfect fitment and maximum strength.

Important notes
