The Landrum Springs K15-125 rear coil spring is engineered for vehicles requiring a durable, load-rated suspension upgrade that delivers consistent handling and ride quality. This 5-inch diameter rear spring is designed for custom builds, restorations, and performance modifications where factory springs fall short of handling increased weight, towing capacity, or lowered chassis geometry.
Whether you're building a hot rod, upgrading a classic truck, or fine-tuning a modern vehicle's suspension package, this spring provides the structural foundation needed for predictable chassis dynamics and longevity. Landrum Springs manufactures this rear coil spring with a 125 lbs/inch spring rate—a moderate rate ideal for street applications and daily-driven vehicles that need compliance over rough surfaces without excessive body roll.
The 5-inch coil diameter provides excellent space efficiency in tight rear suspension bays while maintaining the spring's ability to compress and extend smoothly under load cycles. The 15-inch free length ensures proper installation geometry in aftermarket and OEM suspension systems where ride height and travel limits must remain within specification. This spring is ideal for mechanics and enthusiasts restoring classic muscle cars, building street rods, or upgrading independent suspension systems.
