10.5in x 5in x 225# Rear Spring

The 10.5in x 5in x 225# Rear Spring from Landrum Springs is engineered for drivers and fabricators who demand precision load control in custom suspension builds. Whether you're tuning a street machine, drag racer, or handling lifted truck geometry, this rear spring delivers the consistent ride height and weight distribution that separates a well-balanced chassis from one that fights you on the road. Landrum Springs has built its reputation on manufacturing coil springs that perform reliably under demanding conditions, making this 225-pound spring a trusted choice for serious automotive modification work.

At 225 pounds of spring rate, this coil spring provides moderate support ideal for rear-end applications where you need to balance payload capacity with ride comfort. The 10.5-inch free length and 5-inch outer diameter dimensions make it compatible with most factory and aftermarket rear suspension mounting points, while the compact footprint allows integration into tightly packaged custom frames. Landrum's high-tensile steel construction resists fatigue and maintains consistent spring rate across thousands of compression cycles—critical when suspension geometry or weight transfer changes demand predictable performance lap after lap or mile after mile.

This spring suits builders working on independent rear suspension conversions, lowered street cars, and applications where factory springs prove too soft or too stiff. Installers should verify mounting pad clearance and confirm that 225# rate matches their vehicle's total rear load (fuel, passengers, cargo) to ensure ride height stability and prevent binding. Proper spring selection requires accounting for antiroll bar stiffness, shock valving, and weight distribution—pairing this spring with matched dampers and geometry optimization yields the handling response that separates amateur builds from dialed-in machines. Always reference your suspension designer's spring rate recommendations before installation.
