Rear Dual-Rate Coil Springs in Black with 160–285 lbf/in Spring Rate and 18.5 in Free Height for Land Cruiser 250 Series (2024–Present) - Pair

The Old Man Emu Rear Dual-Rate Coil Springs are engineered for Land Cruiser 250 Series owners who need a specific rear spring configuration based on vehicle load and intended use. Their dual-rate construction combines a 160–285 pound-force-per-inch spring rate with an 18.5-inch free height, while microalloyed steel and controlled manufacturing processes support long-term spring performance.

Old Man Emu develops its coil springs around different load needs and vehicle applications, allowing the suspension to be tuned to how the Land Cruiser 250 Series is configured and used, providing a more targeted spring specification.

A 160–285 pound-force-per-inch spring rate provides two distinct rates. Combined with the 18.5-inch free height, this configuration is designed to provide control while responding to the changing demands placed on the suspension.

Old Man Emu double-scrags each spring before and after shot peening to reduce internal spring stress and enhance spring life. Computer-controlled precision mandrels are used to form the coils consistently to their specified dimensions.

The springs are manufactured from state-of-the-art microalloyed steel selected for resistance to sagging and corrosion, providing the foundation for a durable spring designed for continued use under varying suspension loads.
