TORSION BAR SET – PORSCHE 911, 19mm, STOCK RATE
SKU 1819
Category: Porsche Torsion Bars
The precision-engineered front suspension replacement for the classic Porsche 911. These 19mm torsion bars are designed to restore the legendary handling and "road feel" of the air-cooled 911. Unlike heavy-duty truck upgrades, this SKU is valved to a stock spring rate, making it the perfect choice for purists and restorers looking to replace fatigued factory bars with modern, high-grade alloy components.
Performance & Fitment
Application: Front Torsion Bar Set Diameter: 19mm (OEM Standard Diameter) Spring Rate: Factory Equivalent
Porsche 911: 1965 through 1989 (Standard Chassis)
Porsche 912: 1965 through 1969
Porsche 930 (Turbo): 1975 through 1989 (Verify diameter requirement; some Turbos utilized larger bars for track use)
Note: Engineered as a direct-fit replacement for the front independent suspension.
Premium Construction
Material: Solid 4340 aircraft-grade alloy steel, chosen for its exceptional "torsional memory" and fatigue resistance.
Manufacturing: Centerless ground to a precise 19mm to ensure a perfectly linear spring rate and remove surface micro-imperfections that can lead to stress cracks over decades of use.
Heat Treatment: Through-hardened and shot-peened to ensure the vehicle maintains its specific ride height without the "settling" common in older, worn-out factory steel.
Finish: Industrial-grade powder coating for superior protection against moisture and debris.
⚠️ Installation & Setup Notes
Indexing & Ride Height: These bars utilize the factory splined ends. Correct indexing (clocking) during installation is critical to achieving the proper stance. Small adjustments at the splines result in significant changes at the wheel.
Grease: Always apply a high-quality Moly-based or waterproof grease to the splines before sliding the bars into the A-arms and adjustment caps to prevent future seizing and "creaking" during cornering.
Upgrade Path: If you are preparing your 911 for competitive autocross or track days, consider stepping up to a 21mm or 22mm bar. This 19mm bar is specifically optimized for street comfort and original factory handling dynamics.
