Torsion Bar Set - '65-'86 Porsche 911/912 and 1955-1959 VW Bug (30mm/Solid)
Torsion Bar Set - '65-'86 Porsche 911/912 and 1955-1959 VW Bug (30mm/Tubular)
SKU 1130
Category: Porsche & Volkswagen Torsion Bars The absolute pinnacle of the tubular lineup. These 30mm tubular rear torsion bars provide the massive spring rate required for high-horsepower competition while shedding approximately 5 lbs of unsprung weight. This is the stiffest bar available for this fitment, designed to eliminate rear-end squat and provide surgical handling response in professional-grade Porsche 911/930 or vintage VW race builds.
Performance & Fitment
Application: Rear Torsion Bar Set (Tubular/Hollow) Length: 24 11/16” Diameter: 30mm (Ultimate Competition / Weight Reduction)
Porsche 911 / 912 / 930: 1965 through 1986
Volkswagen Beetle (Swing Axle): 1955 through 1959
Premium Construction
Material: Tubular aircraft-grade alloy steel for an elite strength-to-weight ratio.
Manufacturing: Centerless ground to ensure perfectly uniform wall thickness and a precise, linear spring rate across the entire bar.
Heat Treatment: Through-hardened and shot-peened to maximize fatigue life and prevent "settling" under extreme racing loads.
Finish: Industrial-grade powder coating for long-term protection against the elements and track debris.
⚠️ Critical Fitment Exceptions
Even if your car falls into the year ranges above, you must ensure it does not fall under these exceptions:
❌ G50 Transmission Porsche 911: This SKU is incompatible with 1987–1989 Porsche 911 models. The G50-equipped cars require longer torsion bars and have a different spline configuration.
❌ Post-1959 VW Beetle: These are "short" 24 11/16" bars. They are incompatible with 1960–1968 Swing Axle models (26 11/16" bars) and 1969+ IRS models (21 3/4" bars).
❌ Maximum Stiffness Warning: A 30mm spring rate is roughly 250% stiffer than a factory 22mm bar. Even with the weight savings of a tubular design, the ride will be extremely rigid. This setup is strictly recommended for dedicated track vehicles, heavy V8-conversion sand rails, or professional-grade drag racing only.
