Cusco 684 316 S Rear Strengthened Sway Bar Bracket Set Link Side & Body Side

The Cusco 684 316 S is a Strengthened Rear Sway Bar Bracket Set that includes both the link-side and body-side brackets, designed to replace the factory mounting hardware with a significantly more rigid alternative. The stock rear stabilizer bar mounting points on these Subaru platforms are known to flex and, under sustained performance driving loads, can crack or tear away from the chassis entirely — especially when paired with an upgraded aftermarket sway bar.

Cusco engineered this reinforcement kit to eliminate that weak point. By upgrading both bracket positions simultaneously, the set ensures that sway bar forces are transferred directly and efficiently into the chassis without loss through bracket flex, improving the overall responsiveness and consistency of the rear suspension.

Key Features:

• Complete set — includes both link-side and body-side reinforcement brackets
• Heavy-duty construction — engineered to withstand the elevated stress loads of performance and upgraded sway bars
• Direct-fit replacement — bolt-on installation using factory mounting locations
• Eliminates bracket flex that can compromise sway bar effectiveness and chassis integrity
• Compatible with BP5 (turbo), BPE (NA, excl. 3.0 Outback), BL5 (turbo), and BLE (NA) chassis — Applied Models A–C
• Manufactured by Cusco (Carrosser Co., Ltd.), an ISO 9001-certified Japanese performance parts manufacturer
