Chevrolet 225 Single-Lea

The LANDRUM SPRINGS Chevrolet 225 Single-Leaf spring (model 21-146SP) is a mono-leaf replacement suspension component engineered for vehicles requiring a 6.500-inch arch and 225 lb/in spring rate. Built from steel with black paint finish, this leaf spring is designed for vehicles in the 3,350–3,600 lb weight range and delivers the consistent load support and ride characteristics that suspension engineers specify for independent rear end geometry typical of Chevy Camaro applications.

The 225 lb/in spring rate is the critical specification here—it determines how much resistance the leaf spring exerts per inch of compression. For vehicles in this weight class, this rate balances compliance for street driving with adequate support under load or cornering stress. The single-leaf mono-leaf design simplifies the suspension stack compared to multi-leaf assemblies, reducing unsprung weight and improving responsiveness. At 23.1 lbs and 58 inches in overall length, the spring integrates with existing attachment points on compatible Chevy platforms without requiring frame or mounting modifications.

This spring is suited for restoration work, performance rebuilds, or replacement on classic and muscle car platforms where OEM or OEM-equivalent suspension geometry is required. Users performing rear suspension work on Camaro-series vehicles—whether returning a car to factory spec or upgrading an existing assembly—rely on accurately rated leaf springs to maintain proper ride height, load distribution, and handling balance. The black paint protects against corrosion during storage and installation. Each unit ships as a single spring, allowing buyers to purchase matched pairs or individual replacements as needed for their specific application.
