Coil Spring Conv Rear 13in x 5in x 235lb

The Swift Springs Coil Spring Conventional Rear 13-inch x 5-inch x 235lb (model 130-500-235 TH) is a precision suspension component designed for applications that require controlled vertical compliance and consistent load support. This rear coil spring is ideal for vehicle recovery systems, off-road suspension builds, and field equipment platforms where spring rate precision is essential.

Engineered with a 235 lb/in spring rate, this coil spring combines moderate stiffness with responsiveness across various payload scenarios. Its tight helix design maximizes structural integrity while maintaining predictable compression characteristics under repeated cycling. Constructed from high-strength steel with a black powder coat finish, this spring resists corrosion and abrasion during field deployment.

Users upgrading existing suspensions or assembling custom load-bearing frames will benefit from the clearly specified spring constants, allowing for accurate calculations of deflection and ensuring that matching pairs deliver symmetrical performance. The powder coat protects the steel from moisture and salt spray, making it critical for extended storage and variable climate conditions.
