Cusco 329 311 A28 28mm Front Sway Bar with Bushings

The Cusco 329 311 A28 is a 28mm front sway bar (anti-roll bar) engineered to significantly reduce body roll and improve cornering stability. Upgrading from the factory 26mm bar to this 28mm unit delivers 128% of the stock spring rate, providing noticeably sharper and flatter handling without sacrificing ride comfort on normal driving surfaces.

Key Features:

• 28mm outer diameter — upgraded from the factory 26mm bar for increased torsional stiffness
• 128% stiffer than stock — reduces weight transfer and body lean during aggressive cornering
• Non-adjustable, 2-point design — simple, direct bolt-on fitment using factory mounting locations
• Steel construction — high-strength steel bar resists torsional flex under hard driving
• Bushings included — complete kit with all necessary mounting hardware
• Iconic Cusco blue finish — powder-coated in Cusco's signature blue for a clean, performance-oriented appearance
• Estimated installation time: ~0.5 hours — minimal tools and no major modifications required

Cusco sway bars replace the factory anti-roll bar using the stock mounting locations, making installation straightforward for any enthusiast. The increased diameter and steel construction provide greater resistance against torsion, keeping the chassis stable during cornering and reducing unwanted weight transfer. Unlike stiffer spring setups, a properly rated sway bar upgrade allows you to improve cornering flatness while preserving day-to-day ride quality.
