Key Features

Designed for precision and long-lasting performance, the aFe Sway-A-Way Rear Shock Kit includes:

• 2.5-inch diameter shock bodies with piggyback reservoirs for improved heat dissipation and consistent damping
• Adjustable ride height to support a 6-inch lift setup
• Bright zinc-plated steel cylinders for enhanced corrosion resistance and durability
• CNC-machined aluminum components manufactured to tight tolerances for superior fit and finish
• Polished nitro steel shafts engineered for increased strength and resistance to bending
• Multi-seal carrier system that prevents fluid leakage and extends service life
• Teflon-lined steel spherical bearings to ensure smooth articulation and reduce wear
• Internal floating piston design for consistent damping performance under varied conditions
• Fully rebuildable construction allowing for long-term maintenance and customization
• Filled with full synthetic shock oil optimized for extreme temperature and usage conditions

Construction & Design

Each shock absorber in the Sway-A-Way kit is 100% designed and manufactured in the USA, reflecting a commitment to quality and precision engineering. The combination of zinc-plated steel cylinders and CNC-machined aluminum parts creates a lightweight yet robust structure capable of withstanding the demands of off-road driving.

The polished nitro steel shafts provide exceptional durability against bending and corrosion, while the multi-seal carrier system ensures zero fluid leakage, maintaining consistent shock performance over time. The internal floating piston works in tandem with full synthetic oil to deliver smooth, fade-resistant damping during extended off-road excursions. Additionally, Teflon-lined spherical bearings reduce friction and wear, promoting quiet and reliable suspension articulation.

Installation & Fitment

This rear shock kit is a direct bolt-on replacement for Jeep Wrangler models from 2007 through 2018 and Jeep Grand Cherokee models from 2005 through 2010, covering various trims including Rubicon, Sahara, Sport, and Anniversary editions. Installation requires no special modifications or tools, making it accessible for experienced DIY installers or professional shops.

The kit includes rear coil springs that provide an additional 1 to 2 inches of lift, complementing the 6-inch shock length to improve ground clearance and suspension articulation. This ensures your Jeep maintains proper suspension geometry and handling characteristics after lift installation.
