13in. x 5in. x 275# Rear Spring

The Landrum Springs 13in. x 5in. x 275# Rear Spring is a precision coil spring engineered for rear suspension applications demanding consistent load support and controlled ride characteristics. This Gold Series conventional coil spring delivers a 275 lb/in spring rate, making it suitable for vehicles requiring firm spring support without excessive harshness. The 5-inch outer diameter and 13-inch length accommodate standard rear suspension geometry, while the gold powder coat finish resists corrosion and provides long-term durability in demanding environments.

Spring rate is the critical specification that determines how much force is required to compress the spring one inch. At 275 lb/in, this rear spring provides moderate resistance suitable for vehicles carrying moderate loads or those prioritizing ride quality over maximum stiffness. The conventional design ensures predictable performance across a wide temperature range and loading cycle. Steel construction with gold powder coat finish offers excellent corrosion resistance, particularly important for vehicles exposed to salt air, road chemicals, or high-humidity environments. The precision manufacturing standards typical of Landrum Springs products ensure minimal variation between units and reliable performance over extended service life.

This rear spring is designed for restoration, repair, and custom suspension builds where OEM replacement or upgraded spring rates are required. It serves pickup truck, SUV, and heavy-duty vehicle applications where load-carrying capability and consistent handling are essential. Buyers typically select springs in this rate range when factory suspension has softened, when vehicle modifications require stiffer geometry, or when matching original equipment specifications is necessary. Verification of vehicle compatibility and suspension configuration is essential before installation to ensure proper fit and performance.

Coil springs in the 275 lb/in range occupy the mid-range of automotive suspension stiffness. Lighter-duty applications use 150–200 lb/in springs for maximum comfort; heavier-duty and performance builds use 300+ lb/in springs for load capacity and reduced body roll. The 13-inch length and 5-inch OD are industry-standard dimensions for full-size truck and SUV rear suspensions, though application-specific verification is critical before purchase.
