• Durable powder coat finish available in red or black
• Premium upper ball joints pre-installed for convenience
• CNC laser-cut ½" thick ball joint pad with relocated mounting for 1-2 degrees additional caster
• TIG-welded 4130 chromoly threaded tube adapters ensure thread durability

Each A-arm is precision bent, CNC notched, and jig welded to ensure consistent fitment and alignment. The premium rod ends function as non-binding bushings, ensuring smooth suspension movement throughout the full range of travel. The redesigned ball joint pad features an improved angle specifically engineered for lowered applications, providing the most clearance of any A-arm on the market. Proudly manufactured in Philipsburg, Pennsylvania, USA.
