• 3-Way adjustable end links allow for tuning of sway bar stiffness to match driving preference and suspension setup.
• A professional wheel alignment is recommended after installation if other suspension components are modified concurrently.

Features

• 25mm tubular rear sway bar - designed to reduce rear body roll and improve handling balance across all listed Ram 1500 and Ram 3500 applications
• 3-Way adjustable design allows the driver to tune rear roll stiffness: soft, medium, or firm, depending on load, driving style, and suspension setup
• Tubular construction reduces unsprung weight compared to solid bars of equivalent diameter while maintaining high torsional rigidity
• Precision-engineered geometry ensures correct end-link alignment and full suspension articulation without binding
• Integrates seamlessly with OEM suspension and with Eibach PRO-KIT and SPORTLINE spring setups as part of a complete handling system
• Reduces rear axle lift and body lean during cornering, acceleration, and braking for a more planted, confidence-inspiring feel
• Includes greasable urethane bushings for long-term durability, resistance to cracking, and easy maintenance
• All necessary mounting hardware included - no additional brackets or modifications required
• Direct bolt-on installation using factory mounting locations - no drilling required
• Made in the U.S.A. - manufactured at Eibach's facility in Corona, California

Product Description

The Eibach E40-27-011-01-01 ANTI-ROLL-KIT is a 25mm tubular rear sway bar engineered for a wide range of Dodge and Ram 1500 trucks from 2009 through 2024, as well as the 2010-2012 Ram 3500 4-Door non-Dually with the 6.7L Cummins Diesel. This rear sway bar directly addresses the Ram's factory rear stabilizer limitations by delivering substantially more rear roll resistance, which translates to reduced body lean in corners, improved stability under towing or loaded conditions, and a more balanced front-to-rear handling feel. The tubular design keeps the bar lightweight while achieving the torsional stiffness needed to meaningfully improve roll control over the factory unit.

A key feature of this bar is its 3-way adjustability. Three mounting positions on the end links allow the sway bar's effective stiffness to be tuned without removing or replacing any hardware - a softer setting suits daily street driving and loaded towing, a medium setting delivers a balanced all-around feel, and the firmest setting provides maximum body roll reduction for more aggressive driving or performance applications. The bar includes greasable urethane bushings at the chassis mounting points, which are significantly more resistant to wear and deterioration than the OEM rubber units and can be easily re-greased through the included Zerk fittings for long-term performance.

This kit is a direct bolt-on rear stabilizer bar replacement using the factory mounting locations - no drilling, cutting, or structural modifications are required. It is fully compatible with stock suspension as well as Eibach PRO-KIT and SPORTLINE performance lowering spring setups, making it a natural complement to a complete Eibach handling upgrade. The rear sway bar only is included; owners seeking a front sway bar upgrade should verify available Eibach ANTI-ROLL-KIT front bar part numbers for their specific Ram model year and drivetrain configuration. The Ram 3500 Dually configuration is not compatible and is explicitly excluded.
