Spring Rear 5in Dia x 15in 125lbs

The Landrum Springs K15-125 is a 5-inch diameter rear coil spring engineered for suspension tuning on vehicles requiring a 125 lb/in spring rate. This gold-series conventional coil spring delivers consistent load support and ride control, with a 15-inch compressed length designed to fit standard rear suspension mounting points. The gold powder-coat finish provides corrosion resistance in demanding environments, making it suitable for both on-road and off-road applications where suspension compliance matters.

With a 125 lb/in spring rate, this rear coil spring offers moderate resistance to compression—ideal for vehicles running modest loads or seeking balanced comfort and handling. The 5-inch outer diameter integrates with existing suspension architecture without requiring frame modification. At 15 inches in length, the spring compresses within typical ride-height parameters while maintaining predictable force delivery across the suspension travel range. Steel construction ensures durability through repeated compression cycles, while the gold powder coating resists rust and UV degradation in harsh conditions including salt spray and extreme temperatures.

This spring suits owners upgrading aging suspension systems, tuning ride quality after lifting or lowering, or replacing worn OEM components. Vehicle enthusiasts working on custom builds, restoration projects, or performance adjustments will find the consistent rate and proven Landrum Springs manufacturing reliability valuable. The rear-specific design works in tandem with front coil springs to achieve balanced weight distribution and predictable handling dynamics across varying road surfaces.

Landrum Springs has established its reputation in the suspension aftermarket through consistent quality control and precise rate specifications. Conventional coil spring designs like this remain the industry standard for passenger vehicles and light trucks, offering proven performance and straightforward installation compared to more complex suspension systems. When replacing or upgrading rear suspension springs, matching the correct spring rate to vehicle weight and intended use is critical—the 125 lb/in specification on this K15-125 addresses a common middle-ground requirement.

Sold individually, this spring must typically be paired with a matching unit for the opposite rear side to maintain symmetrical suspension behavior. Verify compatibility with your vehicle's suspension mounting pattern and load requirements before purchase. The gold powder coat may vary slightly in appearance depending on lighting conditions but maintains consistent protective properties across the coil surface.
