Total Chaos Stock Length 4130 Expedition Series Lower, 2024+ Toyota Land Cruiser 250, 2025+ 4Runner

Stock ball joints and rubber bushings eventually wear out and must be replaced. Sloppy steering and uneven tire wear are common when these parts become worn out or damaged. You cannot individually order bushings or ball joints from Toyota for the factory lower control arms.

LCA's are 100% bolt-on and upgrade ball joints to a 1" stainless steel uniball to maximize strength. Rubber bushings are replaced with urethane bushings to provide better off road trail handling and steering response. Less bushing deflection allows the vehicle steering to be more responsive at higher speed on and off road.

These fully rebuildable lower control arms are hand crafted from 4130 chromoly construction making them much stronger than the stock units.

• Light weight. Maximum ground clearance compared to stock units. Fully rebuildable. 100% Bolt-on.
• Increased caster added. Lower uniball moved forward 1/4 inch for better overall handling.
• Billet CNC machined uniball cup houses a 1 inch 100% stainless steel uniball that upgrades the factory ball joints for greater articulation and strength.
• Integrated steering stop tabs retain factory turning angles.
• Urethane pivot bushings reduce deflection compared to a rubber bushing offering a tighter steering feel. Zerk fittings allow for easy maintenance.
• 4130 chromoly laser cut plates are fully boxed and include internal gussets.
• Recessed jack point integrated into arm bottom plate.
• Single shock capability while retaining factory sway bar mounting location.
• Three stage powder coat includes a durable clear coat.
