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 use of CNC machining guarantees exact tolerances for reliable fitment and performance. The polished nitro steel shaft enhances strength and corrosion resistance, critical for off-road durability.

The multi-seal carrier system effectively prevents fluid leakage, ensuring consistent damping performance over extended use. The internal floating piston design separates the shock oil from nitrogen gas, reducing aeration and improving shock response during demanding off-road conditions. Additionally, Teflon-lined spherical bearings provide smooth articulation, reduce friction, and extend the service life of the shocks.
