Product Description

The Eibach E40-59-004-01-01 ANTI-ROLL-KIT is a 22mm rear sway bar engineered specifically for the 2015-2025 Lexus IS F Sport in RWD configuration on the XE30 platform - covering the IS200t (2015-2017), IS300 F Sport (2018-2025), and IS350 F Sport (2014-2025). The factory rear stabilizer bar on the XE30 IS is calibrated for ride comfort over performance, which leaves meaningful body roll and rear axle loft on the table during spirited cornering. Eibach's 22mm replacement bar directly addresses this by increasing rear roll resistance, flattening the car's cornering stance, and promoting a more neutral, confidence-inspiring handling balance - all without sacrificing ride quality under normal driving conditions.

The bar is forged from high-strength steel with no weld joints, giving it consistent and predictable torsional stiffness throughout its service life. Greasable urethane bushings replace the factory rubber mounts at the chassis attachment points, providing significantly better longevity and a more direct, responsive connection between the bar and chassis. The bushing design resists the cracking and compression set that deteriorates rubber bushings over time, and the included Zerk-style fittings allow for easy re-greasing during routine maintenance. Installation is a direct bolt-on replacement at the factory rear sway bar mounting positions - no special fabrication or chassis modification is required.

This kit fits F Sport and RWD configurations only. The IS300 AWD, IS350 AWD, and non-F Sport base or Luxury trim variants are not listed by Eibach for this part number and should not be assumed as compatible. Owners who want to upgrade both front and rear stabilizers can reference Eibach's 29mm front sway bar (E40-59-004-01-10) or the complete front-and-rear combo kit (E40-59-004-01-11). This rear bar pairs directly with Eibach's PRO-KIT (E10-59-004-01-22) and SPORTLINE (E20-59-004-01-22) spring kits to form a complete, cohesive suspension upgrade for the XE30 IS F Sport.
