This OE Match spring plate is a direct replacement for the original Porsche rear suspension component fitted to Porsche 356 Pre-A, 356A, and 356B models. Manufactured to OE specifications, it replicates the factory closed-type design used in the classic rear torsion bar suspension system.

Installed at the rear suspension assembly, the spring plate acts as the mounting and support point for the torsion bar. It transfers suspension load from the rear axle into the torsion bar system, helping maintain proper ride height and suspension geometry. The closed-type construction provides improved rigidity, durability, and protection of the torsion bar mounting area compared to open-style versions.
The spring plate supports and positions the rear torsion bar within the suspension system. It helps maintain correct ride height, rear wheel alignment, and suspension stability while transferring load between the chassis and rear axle.
Function
• Supports rear torsion bar suspension system
• Maintains proper ride height and suspension geometry
• Transfers load between rear axle and chassis
• Helps stabilise rear suspension movement
• Provides durable mounting point for torsion bar assembly
Over time, original spring plates can suffer from corrosion, fatigue, or deformation due to decades of suspension load and environmental exposure. Worn or damaged spring plates may affect ride height, wheel alignment, and overall handling stability. Replacing the component restores suspension integrity, improves chassis stability, and helps maintain original driving characteristics.
When to replace
• Rear suspension sagging or uneven ride height
• Visible corrosion or fatigue cracks
• Excessive rear suspension movement or noise
• Suspension alignment instability
• During full suspension restoration or torsion bar servicing
