Torsion Bar
By OE Match
- Porsche 356B 1959-63
- Porsche 356C 1963-65
This OE match rubber bushing is a direct replacement for the original Porsche component used in the rear torsion bar suspension system of 356 models. Installed at the outer section of the torsion bar tube, it supports the spring plate while isolating vibrations and maintaining correct suspension alignment.
Sold individually, 2 required per vehicle
Fits:
Porsche 356 BT5-T6
Porsche 356 C
Diagram ref no 36
This bushing cushions the connection between the torsion bar spring plate and the chassis. It absorbs road vibrations and reduces metal-to-metal contact, helping maintain smooth suspension movement and ride comfort while preserving alignment.
Function
• Cushions and supports the rear spring plate at the torsion housing
• Absorbs vibration and road shock
• Maintains correct suspension alignment and geometry
• Prevents metal-to-metal contact within the suspension system
• Allows controlled torsion bar movement
Over time, rubber bushings degrade due to age, heat, and exposure to the elements. Worn bushings can cause excessive play, poor alignment, and increased vibration, negatively affecting ride quality and handling. Replacing them restores proper suspension function, improves comfort, and protects surrounding components.
When to replace
• Visible cracking, splitting, or hardening of rubber
• Excessive rear suspension play or noise
• Uneven ride height or alignment issues
• During suspension rebuild or restoration
• Signs of deterioration due to age or contamination

OEMatch Torsion Bar — Control, Stability, Comfort
Torsion bars are a key element of Porsche suspension, providing spring resistance that supports vehicle weight, controls ride height and helps manage wheel movement. OEMatch supplies torsion bars and related suspension hardware suitable for restoration, routine servicing and measured performance upgrades on Porsche models.
Available Types
- Road specification
- Sport specification
- Track specification
Understanding OEMatch Torsion Bar
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original torsion bars.
OE (Original Equipment) refers to parts matching original specifications for the torsion bars and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM torsion bars engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Torsion bars act as the primary spring in many Porsche suspension layouts. They twist along their axis when the wheels move, absorbing impact and controlling compression and rebound. Correct material selection and section diameter determine stiffness and longevity; careful installation and correct mounting hardware help preserve alignment and ride height. Torsion bars also allow incremental adjustment to fine-tune chassis balance.
Benefits Include
- Restores correct ride height and chassis balance
- Improves handling predictability and cornering stability
- Permits measured adjustment of suspension stiffness for road or track use
- Made from high-tensile spring steel for consistent resistance
Why Torsion Bar Wear and Fail
- Metal fatigue from repeated torsional loading
- Corrosion or pitting that reduces cross-section and strength
- Cracking caused by overload or impact
- Worn bushings or mounts that alter load distribution
The Importance of Replacing with OEMatch Torsion Bar
Replacing worn or damaged torsion bars restores ride height accuracy, alignment and predictable handling, which are important for Porsche models. Correctly sized replacements help maintain chassis geometry and vehicle balance; selecting the right specification supports restoration goals or tuned handling without introducing unintended stress to adjacent suspension components.
Advantages
- Direct-fit alternatives made to original-spec dimensions and tolerances
- Available in standard and performance diameters to suit intended use
- Manufactured from performance-grade spring steel for durability
