6th Coil Assm. Alum

The WEHRS Machine 6th Coil Assembly Aluminum (WM291) is a bolt-on coil assembly designed for suspension systems requiring reliable spring articulation and load management. Built from aluminum construction with black anodized finish, this 4-inch spring coil assembly provides a lightweight alternative to steel options while maintaining structural integrity under field conditions. The kit format allows for straightforward installation on compatible platforms.

Weighing 1.31 lbs and measuring 4.95 x 2.8 x 9.4 inches, the aluminum construction delivers a favorable strength-to-weight ratio for applications where unsprung mass reduction improves ride quality and responsiveness. The black anodized finish provides corrosion resistance and a professional appearance, critical for systems operating in harsh environments or extended field deployments. The 4-inch spring rate is engineered to work within the WEHRS Machine ecosystem of suspension components, ensuring compatibility with matched systems.

This assembly suits operators and technicians building or upgrading suspension systems where aluminum coil reliability is essential. Off-road platforms, tactical vehicles, and equipment carriers benefit from the lightweight profile and bolt-on convenience of this design. WEHRS Machine components are recognized in the suspension aftermarket for precision engineering and durability in demanding conditions.

The 6th Coil Assembly is sold as a complete kit, simplifying procurement for builders and fleet maintenance operations. Verify compatibility with your specific suspension platform before purchase, as coil assemblies must match the intended vehicle or equipment system to ensure proper spring rate and articulation characteristics.
