aFe Control Sway-A-Way bypass shocks offer superior, externally adjustable, position-sensitive damping for extreme off-road performance while maintaining on-road comfort. They feature robust CNC-machined components, large diameters for heat dissipation, and durable materials. These position-sensitive bypass shocks typically have two compression tubes and one rebound tube, which allows you to tune both compression and rebound to better suit various terrains without sacrificing ride quality. Key features and benefits: * They feature red anodized CNC machined aluminum components and nickel flashed, zinc plated, and clear coated steel cylinder bodies for exceptional corrosion resistance * Externally adjustable bypass technology * Multi-Seal carrier to ensure zero leakage * Nitrobrite polished steel shafts provide longer seal life and are harder than standard chrome shafts * Specifically formulated (7wt), full synthetic shock oil * Available with piggyback reservoirs for easy mounting, or remote reservoirs when space is limited
