Torsion Bar Set - Porsche 911 - 26 MM

A precision-engineered rear suspension upgrade for the classic Porsche 911. These solid 26mm torsion bars are a popular "step-up" from factory settings, designed to significantly reduce rear-end squat during acceleration and body roll during cornering. This diameter is ideal for owners of "G-Body" 911s or early long-hood models who have added more horsepower or are running modern performance tires and want a more planted, communicative rear end.

Performance & Fitment

Application: Rear Torsion Bar Set

Diameter: 26mm (Performance Street / Light Track)

Type: Solid

Spring Rate: Substantial upgrade over stock (Standard Carrera 3.2 factory bars were typically 24mm or 25mm).

• Porsche 911: 1965 through 1989

• Porsche 912: 1965 through 1969

• Porsche 930 (Turbo): 1975 through 1989

• Fitment Note: These are direct-fit replacements for the factory rear bars. They slide into the rear torsion tube and interface with the rear spring plates.

Premium Construction

• Material: Forged from aircraft-grade 4340 alloy steel, providing exceptional fatigue resistance and "torsional memory" (the ability to return to the original position without sagging).

• Manufacturing: Centerless ground to a precise 26mm diameter. This process ensures the spring rate is perfectly linear and removes any surface pits or imperfections that could lead to stress fractures over time.

• Heat Treatment: Through-hardened to optimize strength and longevity, ensuring the car maintains its corner-balanced ride height.

• Finish: Industrial powder coating for maximum protection against moisture, road salt, and debris.

⚠️ Installation & Performance Notes

• System Balance: Suspension tuning is about ratios. If you increase the rear bar size to 26mm, you should ensure your front torsion bars are matched accordingly (typically paired with 21mm or 22mm front bars) to prevent excessive oversteer.

• Indexing and Ride Height: Setting the ride height on a 911 is done by "clocking" the splines on the torsion bar. Because the 26mm bar is stiffer than stock, the car will sit higher than it did with the factory bars if indexed at the same angle.

• Bushings: This is the perfect time to inspect or replace your rear spring plate bushings. High-performance bars work best when paired with fresh polyurethane or Neatrix bushings to eliminate "stiction."

• Lubrication: Clean the splines thoroughly and apply a generous amount of waterproof, anti-seize grease to both ends of the bar. This prevents the bars from "creaking" and ensures they won't seize in the tube for future adjustments.
